reimbursement exists among third-party payors; coverage and reimbursement can differ significantly from payor to payor. In addition, payors continually review new products for possible coverage and can, without notice, deny coverage. As a result, the coverage determination process is often time-consuming and costly; requiring us to provide scientific and clinical support for the use of our products to each payor separately, with no assurance that coverage and adequate reimbursement will be obtained, or maintained if obtained. Coverage decisions may depend upon clinical and economic standards that disfavor new products when more established or lower cost therapeutic alternatives are already available or subsequently become available. Any decline in the amount payors are willing to reimburse our customers for procedures using our products, including the amount payors are willing to pay the physicians performing the procedures, which is separately evaluated, could make it difficult for existing customers to continue using, or new customers to adopt, any of our products and could create additional pricing pressure for us. If we were forced to lower the price we charge for our products, our gross margins would decrease, which would adversely affect our ability to invest and grow our business. Further, we believe that future coverage and reimbursement will likely be subject to increased restrictions both in the U.S. and in international markets.
One key aspect of reimbursement in the U.S. is the use of coding. Coding refers to distinct numeric and alphanumeric billing codes that are used by healthcare providers to report the provision of medical procedures and the use of supplies for specific patients to payors. There are different categories of Current Procedural Terminology (CPT) codes (Category I, II and III) based on the procedure or supply. Although we have received a permanent healthcare common procedure coding system J code for our Photrexa pharmaceutical therapies, we have only obtained temporary Category III CPT codes for the professional fees associated with CXL and iStent-related procedures. There is no guarantee that these billing codes or the payment amounts associated with such codes will not change in the future. Prior to expiration, there are two options: submit an application to convert a temporary code to a permanent code or submit an application for a five-year extension of the temporary code. Further, even when a permanent billing code has been assigned to a product, there is no guarantee that coverage will be provided. MACs have in the past, and may in the future, change coverage terms, which could result in inadequate reimbursement and impact the use of our products. If we are unable to maintain our existing codes or obtain new permanent codes for procedures using our products, or obtain new reimbursement codes for our other products in development, we may be subject to significant pricing pressure, which could harm our business, results of operations, financial condition and prospects. Additionally, if we do obtain a permanent Category I CPT code for procedures using our products, certain national reimbursement levels for such procedures may be adjusted at that time. These fee reimbursement levels may be decreased and could have a material adverse effect on our business, financial condition and operating results.
If our competitors are able to develop and market products that are safer, more effective, less costly or otherwise more attractive than our products, our commercial opportunity may be reduced or eliminated.
Our industry is highly competitive and subject to rapid and profound technological, market and product-related changes. Our success depends, in part, upon our ability to maintain a competitive position in the development of new products for the treatment of chronic eye diseases. Our competitors, medical companies, academic and research institutions or others could develop new drugs, therapies, medical devices or surgical procedures that could render our products obsolete. If such other products demonstrate better safety or effectiveness, clinical results, ease of use or lower costs than our products, it may reduce demand for our products, and our business may be harmed.
Many of our current and potential competitors are large publicly traded companies or divisions of publicly traded companies and have more resources, greater name recognition, longer operating histories, more established relationships with healthcare professionals, customers and third-party payors, broader products lines that provide rebate and bundling opportunities, more established sales and marketing programs and distribution networks, and greater experience in obtaining regulatory clearance or approval. If we are unable to effectively compete, it could adversely affect our business.
Ophthalmic surgeons may not use our products if they do not believe they are safe, efficient, effective and preferable alternatives to other treatment solutions in the market or may use our products without being adequately trained, which could result in inferior clinical outcomes.
We believe that ophthalmic surgeons will not use our products unless they conclude that our products provide a safe, efficient, effective and preferable alternative to currently available treatment options. If ophthalmic surgeons determine that any of our products are not sufficiently effective, efficient or safe, whether based on longer-term patient studies or clinical experience or unsatisfactory patient outcomes or patient injury, our sales would be harmed. It is also possible that as our products become more widely used, latent defects could be identified, creating negative publicity and
