Recent Accounting Standards [Abstract]
Recent Accounting Standards	(2) Recent Accounting Standards On January 5, 2016, the Financial Accounting Standards Board (FASB) issued guidance to enhance the reporting model for financial instruments to provide users of financial statements with more decision-useful information. Among the many targeted improvements to U.S. GAAP are (1) requiring equity investments, except those accounted for under the equity method of accounting or those that result in consolidation of the investee, to be measured at fair value with changes in fair value recognized in net income; (2) simplifying the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment; (3) eliminating the requirement to disclose the fair value of financial instruments measured at amortized cost for entities that are not public business entities; and (4) clarifying that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the entity’s other deferred tax assets. This guidance applies to all entities that hold financial assets or owe financial liabilities. For public companies, these amendments are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. We are currently evaluating the impact that the adoption of this guidance may have on the Company's consolidated financial statements. On February 25, 2016, the FASB issued guidance to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and by disclosing key information about leasing arrangements. This guidance sets out the principles for the recognition, measurement, presentation and disclosure of leases for both lessors and lessees. It requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase by the lessee. This classification will determine whether lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease, respectively. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term greater than 12 months regardless of their classification. Leases with a term of 12 months or less will be accounted for similar to existing guidance for operating leases today. The guidance requires lessors to account for leases using an approach that is substantially equivalent to existing guidance for sales-type leases, direct financing leases and operating leases. This guidance is effective for public companies for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. We are currently evaluating the impact that the adoption of this guidance may have on the Company's consolidated financial statements. On March 30, 2016, the FASB issued guidance to For public companies, these amendments are effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. We are currently evaluating the impact the adoption of this guidance may have on the Company's consolidated financial statements. On May 9, 2016, For public companies, these amendments are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. We are currently evaluating the impact the adoption of this guidance may have on the Company's consolidated financial statements. On June 16, For public companies, these amendments are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. We are currently evaluating the impact the adoption of this guidance may have on the Company's consolidated financial statements. Other than the accounting pronouncement disclosed above, there were no other new accounting pronouncements issued during the three months and six months ended June 30, 2016 that could have a material impact on the Corporation’s financial position, operating results or financials statement disclosures.

Given market conditions and the significant judgments involved, there is a continuing risk that declines in fair value may occur and material other-than-temporary impairments may be recorded in future periods. The Corporation from time to time may sell investments as part of its asset/liability management process or to reposition its investment portfolio based on current and expected market conditions. Municipal Securities: contractual cash flows, these investments are not considered other-than-temporarily impaired. Collateralized mortgage obligations Mutual Funds: Obligations of the Commonwealth of Puerto Rico and its Instrumentalities : Besides holdings in escrowed bonds, which are backed by US Government securities and therefore have an implicit AA+/Aaa rating, our exposure is in senior lien bonds issued by Cofina.

Fair Value Measurements [Abstract]
Fair Value Measurements	(5) Fair Value Measurements Assets recorded at fair value in the condensed consolidated balance sheets are categorized based upon the level of judgment associated with the inputs used to measure their fair value. Level inputs, as defined by current accounting guidance for fair value measurements and disclosures, are as follows: Level Input: Input Definition: Level 1 Inputs are unadjusted, quoted prices for identical assets or liabilities in active markets at the measurement date. Level 2 Inputs other than quoted prices included in Level 1 that are observable for the asset or liability through corroboration with market data at the measurement date. Level 3 Unobservable inputs that reflect management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date. The Corporation uses observable inputs when available. Fair value is based upon quoted market prices when available. The Corporation limits valuation adjustments to those deemed necessary to ensure that the security’s fair value adequately represents the price that would be received or paid in the marketplace. Valuation adjustments may include consideration of counterparty credit quality and liquidity as well as other criteria. The estimated fair value amounts are subjective in nature and may involve uncertainties and matters of significant judgment for certain financial instruments. Changes in the underlying assumptions used in estimating fair value could affect the results. The fair value measurement levels are not indicative of risk of investment. The fair value of investment securities is estimated based on quoted market prices for those or similar investments. Additional information pertinent to the estimated fair value of investment in securities is included in note 3. The following tables summarize fair value measurements by level at June 30, 2016 and December 31, 2015 for assets measured at fair value on a recurring basis: June 30, 2016 Level 1 Level 2 Level 3 Total Securities available for sale: Fixed maturity securities Obligations of government-sponsored enterprises $ - $ 71,314 $ - $ 71,314 U.S. Treasury securities and obligations of U.S government instrumentalities 96,622 - - 96,622 Obligations of the Commonwealth of Puerto Rico and its instrumentalities - 28,647 - 28,647 Municipal securities - 709,673 - 709,673 Corporate bonds - 218,269 - 218,269 Residential agency mortgage-backed securities - 822 - 822 Collateralized mortgage obligations - 19,241 - 19,241 Total fixed maturities 96,622 1,047,966 - 1,144,588 Equity securities - Mutual funds 230,610 64,624 14,869 310,103 Total $ 327,232 $ 1,112,590 $ 14,869 $ 1,454,691 December 31, 2015 Level 1 Level 2 Level 3 Total Securities available for sale: Fixed maturity securities Obligations of government-sponsored enterprises - 116,240 - 116,240 U.S. Treasury securities and obligations of U.S government instrumentalities 163,270 - - 163,270 Obligations of the Commonwealth of Puerto Rico and its instrumentalities - 25,619 - 25,619 Municipal securities - 647,446 - 647,446 Corporate bonds - 157,408 - 157,408 Residential agency mortgage-backed securities - 937 - 937 Collateralized mortgage obligations - 22,725 - 22,725 Total fixed maturities 163,270 970,375 - 1,133,645 Equity securities - Mutual funds 167,082 22,031 7,958 197,071 Total $ 330,352 $ 992,406 $ 7,958 $ 1,330,716 The fair value of fixed maturity and equity securities included in the Level 2 category were based on market values obtained from independent pricing services, which utilize evaluated pricing models that vary by asset class and incorporate available trade, bid and other market information and for structured securities, cash flow and when available loan performance data. Because many fixed income securities do not trade on a daily basis, the models used by independent pricing service providers to prepare evaluations apply available information, such as benchmark curves, benchmarking of like securities, sector groupings, and matrix pricing. For certain equity securities, quoted market prices for the identical security are not always available and the fair value is estimated by reference to similar securities for which quoted prices are available. The independent pricing service providers monitor market indicators, industry and economic events, and for broker-quoted only securities, obtain quotes from market makers or broker-dealers that they recognize to be market participants. The fair value of the investments in partnerships included in the Level 3 category was based on the net asset value (NAV) which is affected by the changes in the fair market value of the investments held in these partnerships. Transfers into or out of the Level 3 category occur when unobservable inputs, such as the Company’s best estimate of what a market participant would use to determine a current transaction price, become more or less significant to the fair value measurement. Transfers between levels, if any, are recorded as of the actual date of the event or change in circumstance that caused the transfer. There were no transfers in and/or out of Level 3 and between Levels 1 and 2 during the three months and six months ended June 30, 2016 and 2015. A reconciliation of the beginning and ending balances of assets measured at fair value on a recurring basis using significant unobservable inputs (Level 3) for the three months and six months ended June 30 is as follows: Fair Value Measurements Using Significant Unobservable Inputs (Level 3) Three months ended June 30, Six months ended June 30, 2016 2015 2016 2015 Beginning balance $ 6,997 $ 10,191 $ 7,958 $ 13,349 Realized gains 63 (700 ) 214 1,412 Unrealized in other accumulated comprehensive income (321 ) (519 ) (969 ) (3,302 ) Purchases 8,525 111 8,633 189 Capital distributions (395 ) - (967 ) (2,565 ) Ending balance $ 14,869 $ 9,083 $ 14,869 $ 9,083 In addition to the preceding disclosures on assets recorded at fair value in the condensed consolidated balance sheets, accounting guidance also requires the disclosure of fair values for certain other financial instruments for which it is practicable to estimate fair value, whether or not such values are recognized in the condensed consolidated balance sheets. Non-financial instruments such as property and equipment, other assets, deferred income taxes and intangible assets, and certain financial instruments such as claim liabilities are excluded from the fair value disclosures. Therefore, the fair value amounts cannot be aggregated to determine our underlying economic value. The carrying amounts reported in the condensed consolidated balance sheets for cash and cash equivalents, receivables, accounts payable and accrued liabilities, and short-term borrowings approximate fair value because of the short term nature of these items. These assets and liabilities are not listed in the table below. The following methods, assumptions and inputs were used to estimate the fair value of each class of financial instrument: (i) Policy Loans Policy loans have no stated maturity dates and are part of the related insurance contract. The carrying amount of policy loans approximates fair value because their interest rate is reset periodically in accordance with current market rates. (ii) Policyholder Deposits The fair value of policyholder deposits is the amount payable on demand at the reporting date, and accordingly, the carrying value amount approximates fair value. (iii) Long-term Borrowings The carrying amount of the loans payable to bank – variable approximates fair value due to its floating interest-rate structure. The fair value of the senior unsecured notes payable was determined using broker quotations. A summary of the carrying value and fair value by level of financial instruments not recorded at fair value on our consolidated balance sheets at June 30, 2016 and December 31, 2015 are as follows: June 30, 2016 Carrying Value Fair Value Level 1 Level 2 Level 3 Total Assets: Policy loans $ 8,301 $ - $ 8,301 $ - $ 8,301 Liabilities: Policyholder deposits $ 182,730 $ - $ 182,730 $ - $ 182,730 Long-term borrowings: Loans payable to bank - variable 12,007 - 12,007 - 12,007 6.6% senior unsecured notes payable 24,000 - 19,200 - 19,200 Total long-term borrowings 36,007 - 31,207 - 31,207 Total liabilities $ 218,737 $ - $ 213,937 $ - $ 213,937 December 31, 2015 Carrying Value Fair Value Level 1 Level 2 Level 3 Total Assets: Policy loans $ 7,901 $ - $ 7,901 $ - $ 7,901 Liabilities: Policyholder deposits $ 179,287 $ - $ 179,287 $ - $ 179,287 Long-term borrowings: Loans payable to bank - variable 12,827 - 12,827 - 12,827 6.6% senior unsecured notes payable 24,000 - 19,920 - 19,920 Total long-term borrowings 36,827 - 32,747 - 32,747 Total liabilities $ 216,114 $ - $ 212,034 $ - $ 212,034

The favorable developments in the claims incurred and loss-adjustment expenses for prior period insured events for the three months and six months ended June 30, 2016 and for the six months ended June 30, 2015 are due primarily to better than expected utilization trends. The amount in the incurred claims and loss-adjustment expenses for the prior period insured events for the three months ended June 30, 2015 is due primarily to higher than anticipated utilization trends. Reinsurance recoverable on unpaid claims is reported as premium and other receivables, net in the accompanying consolidated financial statements. The claims incurred disclosed in this table exclude the portion of the change in the liability for future policy benefits expense, which amounted to $6,642 and $13,404 during the three months and six months ended June 30, 2016, respectively. The change in the liability for future policy benefits during the three months and six months ended June 30, 2015 amounted to $5,215 and $12,092, respectively.

Income Taxes	(8) Income Taxes In connection with the Puerto Rico tax code, as amended, on April 15, 2015, the group of corporations that comprise TSM entered into a Closing Agreement with the Puerto Rico Department of Treasury. The Closing Agreement, among other matters, was related with the payment of the preferential tax rate on the increase in value of some of its long-term capital assets, as permitted by Act No. 238 of 2014 and Act No. 44 of 2015. The agreement also covered certain tax attributes of the Corporation. During the three months ended June 30, 2015, as a result of the aforementioned tax laws and the Closing Agreement, the Company: (1) obtained a benefit from the lower tax rate provided under these statutes, (2) reassessed the realizability of some of its deferred taxes and (3) recorded a tax benefit of $3,129. During the three months ended June 30, 2016, our Property and Casualty subsidiary, Triple-S Propiedad, Inc. (TSP), reassessed the tax rate used to measure several temporary differences, from 20% to 39%, which resulted in an increase in the deferred tax expense of approximately $2,633.

Contingencies [Abstract]
Contingencies	(14) Contingencies The following information supplements and amends, as applicable, the disclosures in Note 24 to the Consolidated Financial Statements of the Company’s 2015 Annual Report on Form 10-K. Our business is subject to numerous laws and regulations promulgated by Federal, Puerto Rico, USVI, Costa Rica, BVI, and Anguilla governmental authorities. Compliance with these laws and regulations can be subject to government review and interpretation, as well as regulatory actions unknown and unasserted at this time. The Commissioner of Insurance of Puerto Rico, as well as other Federal, Puerto Rico, USVI, Costa Rica, BVI, and Anguilla government authorities, regularly make inquiries and conduct audits concerning the Company's compliance with such laws and regulations. Penalties associated with violations of these laws and regulations may include significant fines and exclusion from participating in certain publicly funded programs and may require the Company to comply with corrective action plans or changes in our practices. We are involved in various legal actions arising in the ordinary course of business. We are also defendants in various other litigations and proceedings, some of which are described below. Where the Company believes that a loss is both probable and estimable, such amounts have been recorded. Although we believe our estimates of such losses are reasonable, these estimates could change as a result of further developments in these matters. In other cases, it is at least reasonably possible that the Company may incur a loss related to one or more of the mentioned pending lawsuits or investigations, but the Company is unable to estimate the range of possible loss which may be ultimately realized, either individually or in the aggregate, upon their resolution. The outcome of legal proceedings is inherently uncertain and pending matters for which accruals have not been established have not progressed sufficiently to enable us to estimate a range of possible loss, if any. Given the inherent unpredictability of these matters, it is possible that an adverse outcome in one or more of these matters could have a material adverse effect on the consolidated financial condition, operating results and/or cash flows of the Company. Additionally, we may face various potential litigation claims that have not been asserted to date, including claims from persons purporting to have rights to acquire shares of the Company on favorable terms pursuant to agreements previously entered by our predecessor managed care subsidiary, Seguros de Servicios de Salud de Puerto Rico, Inc. (SSS), with physicians or dentists who joined our provider network to sell such new provider shares of SSS at a future date (Share Acquisition Agreements) or to have inherited such shares notwithstanding applicable transfer and ownership restrictions. Claims by Heirs of Former Shareholders In the case entitled Cebollero Santamaría v. Triple-S Salud, Inc., et al, was filed on March 26, 2013, and the Company filed its response on May 16, 2013. On October 29, 2013, the Company filed a motion for summary judgment on the grounds that the claim is time-barred under the fifteen-year statute of limitations of the Puerto Rico Civil Code for collection of monies and, in the alternative, that plaintiff failed to state a claim for which relief can be granted, which was denied by the court. On November 2, 2015, the Company filed a petition of Writ of Certiorari with the Puerto Rico Court of Appeals, which was denied on March 8, 2016. On March 23, 2016, the Company filed a request for reconsideration to its petition of Writ of Certiorari with the Puerto Rico Court of Appeals, which the plaintiff opposed. The Court of Appeals denied reconsideration on April 28, 2016. The Company filed a Writ of Certiorari before the Supreme Court on May 31, 2016. The same has been opposed by the plaintiff. In the case entitled Gallardo Mendez, et al, v. Triple-S Management Corporation, which was filed on December 30, 2014, the Company filed a motion to dismiss on March 13, 2015. After an extension of time granted by the court, plaintiff did not file an opposition. Therefore, on June 16, 2015, the court deemed our motion to dismiss unopposed. On March 18, 2016, the court dismissed the complaint with prejudice. Since plaintiff did not file within 30 days an appeal brief opposing the trial court’s determination, the dismissal of the case is final. Claims Relating to the Provision of Health Care Services On June 5, 2014, ASES initiated an administrative hearing against TSS moved by a primary medical group for alleged outstanding claims related to services provided to Medicaid beneficiaries from 2005 to 2010, totaling approximately $3,000. On June 19, 2014, TSS filed its response. On June 25, 2014, the hearing officer ordered the parties to file a joint working plan and schedule. In the process of executing said plan and after discovery was completed, this matter was settled for $316 on June 6, 2016.

Segment Information [Abstract]
Segment Information	(15) Segment Information The operations of the Corporation are conducted principally through three business segments: Managed Care, Life Insurance, and Property and Casualty Insurance. The Corporation evaluates performance based primarily on the operating revenues and operating income of each segment. Operating revenues include premiums earned, net, administrative service fees, net investment income, and revenues derived from other segments. Operating costs include claims incurred and operating expenses. The Corporation calculates operating income or loss as operating revenues less operating costs. The Managed Care segment participates in the Commonwealth of Puerto Rico Health Insurance Plan (similar to Medicaid) (Medicaid) program to provide health coverage to medically indigent citizens in Puerto Rico, as defined by the laws of the government of Puerto Rico, by administering the provision of the physical health component in designated service regions in Puerto Rico. We served all eight service regions on an administrative service only basis (ASO) until March 31, 2015. Administrative service fees during the six months ended June 30, 2015 amounted to $24,238. Effective April 1, 2015, we started to provide healthcare services to only two regions of the Medicaid program on a risk based model.

Recent Accounting Standards [Abstract]
Recent Accounting Standards	On January 5, 2016, the Financial Accounting Standards Board (FASB) issued guidance to enhance the reporting model for financial instruments to provide users of financial statements with more decision-useful information. Among the many targeted improvements to U.S. GAAP are (1) requiring equity investments, except those accounted for under the equity method of accounting or those that result in consolidation of the investee, to be measured at fair value with changes in fair value recognized in net income; (2) simplifying the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment; (3) eliminating the requirement to disclose the fair value of financial instruments measured at amortized cost for entities that are not public business entities; and (4) clarifying that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the entity’s other deferred tax assets. This guidance applies to all entities that hold financial assets or owe financial liabilities. For public companies, these amendments are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. We are currently evaluating the impact that the adoption of this guidance may have on the Company's consolidated financial statements. On February 25, 2016, the FASB issued guidance to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and by disclosing key information about leasing arrangements. This guidance sets out the principles for the recognition, measurement, presentation and disclosure of leases for both lessors and lessees. It requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase by the lessee. This classification will determine whether lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease, respectively. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term greater than 12 months regardless of their classification. Leases with a term of 12 months or less will be accounted for similar to existing guidance for operating leases today. The guidance requires lessors to account for leases using an approach that is substantially equivalent to existing guidance for sales-type leases, direct financing leases and operating leases. This guidance is effective for public companies for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. We are currently evaluating the impact that the adoption of this guidance may have on the Company's consolidated financial statements. On March 30, 2016, the FASB issued guidance to For public companies, these amendments are effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. We are currently evaluating the impact the adoption of this guidance may have on the Company's consolidated financial statements. On May 9, 2016, For public companies, these amendments are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. We are currently evaluating the impact the adoption of this guidance may have on the Company's consolidated financial statements. On June 16, For public companies, these amendments are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. We are currently evaluating the impact the adoption of this guidance may have on the Company's consolidated financial statements. Other than the accounting pronouncement disclosed above, there were no other new accounting pronouncements issued during the three months and six months ended June 30, 2016 that could have a material impact on the Corporation’s financial position, operating results or financials statement disclosures.
