The accompanying unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial information. Accordingly, the unaudited condensed consolidated financial statements do not include all of the information and notes required by U.S. Generally Accepted Accounting Principles (“GAAP”) for complete financial statements. The accompanying unaudited condensed consolidated financial statements include all adjustments, composed of normal recurring adjustments, considered necessary by management to fairly state the Company’s results of operations, financial position and cash flows. The operating results for the interim periods are not necessarily indicative of results that may be expected for any other interim period or for the full year. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015 as filed with the SEC. The unaudited condensed consolidated financial statements are prepared in conformity with GAAP, which requires the use of estimates, judgments and assumptions that affect the amounts of assets and liabilities at the reporting date and the amounts of revenue and expenses in the periods presented. The Company believes that the accounting estimates employed are appropriate and the resulting balances are reasonable; however, due to the inherent uncertainties in making estimates, actual results could differ from the original estimates, requiring adjustments to these balances in future periods.

Business Combinations [Abstract]
Business Combination	2. Business Combination On April 20, 2015 (the “Closing Date”), the Company acquired substantially all of the assets of Ciscura Holding Company, Inc. and its subsidiaries (“Ciscura”) for $6.2 million in cash, based on the final number of pumps acquired and the associated treatments, which were generated during the 90-day period post-closing from the approximately 100 medical facility relationships Ciscura had prior to the acquisition. The Company acquired approximately 1,800 infusion pumps, its four-person field sales team, as well as its facilities management personnel, which have become the foundation of the Company’s new Southeast facility. Ciscura, based in Alpharetta, GA, was a privately-held Southeastern regional provider of ambulatory infusion pumps and services to medical facilities and provides the Company with a new regional warehouse and service facility that are in close proximity to a number of our largest existing customers, in addition to new customers previously serviced by Ciscura, enabling same day service for equipment and supplies to much of the Southeast region.

Debt	5. Debt On March 23, 2015, the Company and its direct and indirect subsidiaries (the “Borrowers”) entered into a credit agreement (the “Credit Agreement”) with JPMorgan Chase Bank, N.A., as lender (the “Lender”). The Credit Agreement consists of a $27.0 million Term Loan A, up to an $8.0 million Term Loan B and a $10.0 million revolving credit facility (the “Revolver”), all of which mature on March 23, 2020 (collectively, the “Credit Facility”). On March 23, 2015, the Borrowers drew $27.0 million under the Term A Loan to repay and terminate the previously existing credit facility under the credit agreement dated November 30, 2012, as amended, by and among the Company, its direct and indirect subsidiaries, Wells Fargo Bank, National Association, as administrative agent, and certain lenders party thereto (the “WF Facility”). As of June 30, 2016, Term Loan B had a balance of $5.9 million. As of June 30, 2016, interest on the Credit Facility is payable at the Borrower’s choice as a (i) Eurodollar Loan, which bears interest at a per annum rate equal to LIBOR plus a margin ranging from 2.00% to 2.50% or (ii) CBFR Loan, which bears interest at a per annum rate equal to (a) the Lender’s prime rate or (b) LIBOR for a 30-day interest period plus 2.50%, in each case, plus a margin ranging from -0.75% to -0.25%. The actual rate at June 30, 2016 was 2.95% (LIBOR of 0.45% plus 2.50%) on both Term Loan A and B and 3.25% (JPM Chase Prime Rate of 3.5% less 0.25%) on the Revolver. The availability under the Revolver is based upon the Borrowers’ eligible accounts receivable and eligible inventory and is comprised as follows (in thousands): June 30, December 31, Revolver: Gross Availability $ 10,000 $ 10,000 Outstanding Draws (6,618 ) — Letter of Credit — (81 ) Landlord Reserves (45 ) (37 ) Availability on Revolver $ 3,337 $ 9,882 To secure repayment of the obligations of the Borrowers, each Borrower has granted to the Lender, for the benefit of various secured parties, a first priority security interest in substantially all of the personal property assets of each of the Borrowers. In addition, the Company has pledged the shares of InfuSystem Holdings USA, Inc. (“Holdings USA”) and Holdings USA has pledged the shares of each of InfuSystem, Inc. and First Biomedical, Inc. and the equity interests of IFC, LLC to the Lender, for the benefit of the secured parties, to further secure the obligations under the Credit Agreement. In addition, the Credit Agreement requires the Borrowers to maintain the following financial covenant obligations: (i) a minimum fixed charge coverage ratio of 1.25:1.00; (ii) a maximum total leverage ratio ranging from 3.00:1.00 to 2.25:1.00 during specified periods; and (iii) a minimum net worth of $37.5 million As of June 30, 2016, the Borrowers were in compliance with all such covenants.

Earnings Per Share [Abstract]
Earnings Per Share	8. Earnings Per Share Basic income per share is computed by dividing net income by the weighted average number of common shares outstanding during the period. Diluted income per share assumes the issuance of potentially dilutive shares of common stock during the period. The following table reconciles the numerators and denominators of the basic and diluted income per share computations: Three Months Ended Six Months Ended June 30 June 30 2016 2015 2016 2015 Numerator: Net income (in thousands) $ 724 $ 783 $ 1,219 $ 368 Denominator: Weighted average common shares outstanding: Basic 22,620,386 22,381,487 22,584,462 22,345,309 Dilutive effect of non-vested awards 489,484 443,478 485,438 398,639 Diluted 23,109,870 22,824,965 23,069,900 22,743,948 Net income per share: Basic $ 0.03 $ 0.03 $ 0.05 $ 0.02 Diluted $ 0.03 $ 0.03 $ 0.05 $ 0.02 For the three and six months ended June 30, 2016, less than 0.1 million of stock options were not included in the calculation because they would have an anti-dilutive effect, compared to 0.1 million for the same prior year periods.

Accounting Changes and Error Corrections [Abstract]
Recent Accounting Pronouncements and Developments	10. Recent Accounting Pronouncements and Developments In April 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2015-03, Interest – Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs (“ASU 2015-03”), and, in August 2015, the FASB issued ASU No. 2015-15, Interest – Imputation of Interest (Subtopic 835-30): Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements - Amendments to SEC Paragraphs Pursuant to Staff Announcement at June 18, 2015 EITF Meeting (“ASU 2015-15”). ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. ASU 2015-15 then clarified that debt issuance costs related to a line-of-credit arrangement can be presented as an asset on the balance sheet, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. These ASUs are effective for fiscal years beginning after December 15, 2015, and for interim periods within those fiscal years. The Company adopted this guidance as of January 1, 2016, and as a result, has recast the December 31, 2015 consolidated balance sheet to conform to the current period presentation. The adoption of this standard reduced previously presented other assets and long-term debt by $0.1 million, based upon the balance of unamortized debt issuance costs relating to its Credit Facility as of December 31, 2015. In July 2015, the FASB issued ASU No. 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory (“ASU 2015-11”), requiring that inventory be measured at the lower of cost and net realizable value. Net realizable value is defined as estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. ASU 2015-11 is effective within annual periods beginning on or after December 15, 2016, including interim periods within that reporting period. The Company is currently evaluating the impact, if any, that the adoption of this guidance will have on its financial position, results of operations, cash flows and/or disclosures. On May 28, 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”), which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. ASU 2014-09 will supersede the existing revenue recognition guidance in U.S. GAAP when it becomes effective and permits the use of either a retrospective or cumulative effect transition method. In August 2015, the FASB issued ASU No. 2015-14, deferring the effective date of ASU 2014-09 by one year, from January 1, 2017 to January 1, 2018. The Company plans to adopt ASU 2014-09 on January 1, 2018. The Company is evaluating the effect that ASU 2014-09 will have on its financial position, results of operations, cash flows and/or disclosures and has not yet selected a transition method. In November 2015, the FASB issued ASU No. 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes (“ASU 2015-17”), simplifying the balance sheet classification of deferred taxes by requiring all deferred taxes, along with any related valuation allowance, to be presented as noncurrent. ASU 2015-17 is effective for the Company beginning in the first quarter of 2017 and allows for early adoption and may be applied either prospectively or retrospectively. ASU 2015-17 is not expected to have a material impact on the Company’s financial position, results of operations, cash flows and/or disclosures. In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments – Overall: Recognition and Measurement of Financial Assets and Financial Liabilities (“ASU 2016-01”). ASU 2016-01 affects the accounting for equity investments, financial liabilities under the fair value option and the presentation and disclosure requirements of financial instruments. ASU 2016-01 is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company is currently evaluating the impact, if any, that the adoption of this guidance will have on its financial position, results of operations, cash flows and/or disclosures. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) (“ASU 2016-02”). Under ASU 2016-02, an entity will be required to recognize right-of-use assets and lease liabilities on its balance sheet and disclose key information about leasing arrangements. ASU 2016-02 offers specific accounting guidance for a lessee, a lessor and sale and leaseback transactions. Lessees and lessors are required to disclose qualitative and quantitative information about leasing arrangements to enable a user of the financial statements to assess the amount, timing and uncertainty of cash flows arising from leases. For public companies, ASU 2016-02 is effective for annual reporting periods beginning after December 15, 2018, including interim periods within that reporting period, and requires a modified retrospective adoption, with early adoption permitted. The Company is currently evaluating the impact, if any, that the adoption of this guidance will have on its financial position, results of operations, cash flows and/or disclosures.

Recent Accounting Pronouncements and Developments	In April 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2015-03, Interest – Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs (“ASU 2015-03”), and, in August 2015, the FASB issued ASU No. 2015-15, Interest – Imputation of Interest (Subtopic 835-30): Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements - Amendments to SEC Paragraphs Pursuant to Staff Announcement at June 18, 2015 EITF Meeting (“ASU 2015-15”). ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. ASU 2015-15 then clarified that debt issuance costs related to a line-of-credit arrangement can be presented as an asset on the balance sheet, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. These ASUs are effective for fiscal years beginning after December 15, 2015, and for interim periods within those fiscal years. The Company adopted this guidance as of January 1, 2016, and as a result, has recast the December 31, 2015 consolidated balance sheet to conform to the current period presentation. The adoption of this standard reduced previously presented other assets and long-term debt by $0.1 million, based upon the balance of unamortized debt issuance costs relating to its Credit Facility as of December 31, 2015. In July 2015, the FASB issued ASU No. 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory (“ASU 2015-11”), requiring that inventory be measured at the lower of cost and net realizable value. Net realizable value is defined as estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. ASU 2015-11 is effective within annual periods beginning on or after December 15, 2016, including interim periods within that reporting period. The Company is currently evaluating the impact, if any, that the adoption of this guidance will have on its financial position, results of operations, cash flows and/or disclosures. On May 28, 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”), which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. ASU 2014-09 will supersede the existing revenue recognition guidance in U.S. GAAP when it becomes effective and permits the use of either a retrospective or cumulative effect transition method. In August 2015, the FASB issued ASU No. 2015-14, deferring the effective date of ASU 2014-09 by one year, from January 1, 2017 to January 1, 2018. The Company plans to adopt ASU 2014-09 on January 1, 2018. The Company is evaluating the effect that ASU 2014-09 will have on its financial position, results of operations, cash flows and/or disclosures and has not yet selected a transition method. In November 2015, the FASB issued ASU No. 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes (“ASU 2015-17”), simplifying the balance sheet classification of deferred taxes by requiring all deferred taxes, along with any related valuation allowance, to be presented as noncurrent. ASU 2015-17 is effective for the Company beginning in the first quarter of 2017 and allows for early adoption and may be applied either prospectively or retrospectively. ASU 2015-17 is not expected to have a material impact on the Company’s financial position, results of operations, cash flows and/or disclosures. In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments – Overall: Recognition and Measurement of Financial Assets and Financial Liabilities (“ASU 2016-01”). ASU 2016-01 affects the accounting for equity investments, financial liabilities under the fair value option and the presentation and disclosure requirements of financial instruments. ASU 2016-01 is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company is currently evaluating the impact, if any, that the adoption of this guidance will have on its financial position, results of operations, cash flows and/or disclosures. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) (“ASU 2016-02”). Under ASU 2016-02, an entity will be required to recognize right-of-use assets and lease liabilities on its balance sheet and disclose key information about leasing arrangements. ASU 2016-02 offers specific accounting guidance for a lessee, a lessor and sale and leaseback transactions. Lessees and lessors are required to disclose qualitative and quantitative information about leasing arrangements to enable a user of the financial statements to assess the amount, timing and uncertainty of cash flows arising from leases. For public companies, ASU 2016-02 is effective for annual reporting periods beginning after December 15, 2018, including interim periods within that reporting period, and requires a modified retrospective adoption, with early adoption permitted. The Company is currently evaluating the impact, if any, that the adoption of this guidance will have on its financial position, results of operations, cash flows and/or disclosures.
