Trek Health ingests and normalizes Transparency in Coverage data and payer policy updates to give provider organizations a clear view of how commercial reimbursement behaves across markets, payers, and services. Our platform transforms raw payer disclosures into structured intelligence that supports contract evaluation, payer negotiations, and service line strategy. By combining market benchmarks with ongoing policy visibility, Trek helps teams identify variability, risk, and opportunity in commercial reimbursement. The result is faster insight, stronger negotiating positions, and more informed financial decisions.

Prior Authorization

Prior authorization required with clinical documentation

Providers must submit documentation of patient age, baseline serum uric acid >= 7 mg/dL, G6PD screening result showing no deficiency, prior trial/intolerance or failure of xanthine oxidase inhibitors when applicable, evidence of gout severity (e.g., two or more gout flares per year, nonresolving subcutaneous tophus, or radiographic damage), and either a plan for concomitant methotrexate or documentation that methotrexate is contraindicated or not clinically appropriate.

J2507

Documentation Required

Baseline and ongoing lab documentation

Submit baseline serum uric acid documentation >= 7 mg/dL. For renewals, submit serum uric acid < 6 mg/dL prior to the scheduled infusion and document absence of unacceptable toxicity.

Clinical Evidence & References

Clinical trials demonstrated significant reductions in serum uric acid, improvements in tophi (tophus resolution), and reductions in gout flares; common adverse events reported include infusion reactions and gout flares (also nausea and bruising). Examples of serious toxicities referenced for renewal include anaphylaxis, infusion reactions, exacerbation of congestive heart failure, and hemolytic reactions (including methemoglobinemia and hemolysis).

Background

Pegloticase (Krystexxa) is a PEGylated uric acid–specific enzyme indicated for the treatment of chronic gout in adult patients who are refractory to conventional therapy. The mechanism is enzymatic uric acid degradation via a PEGylated uricase. Clinical trials demonstrated marked reductions in serum uric acid, tophus improvement/resolution, and reduced frequency/severity of gout flares. Main adverse events include gout flares and infusion reactions; other reported reactions include nausea and contusion/ecchymosis. Serious toxicities cited in renewal criteria include anaphylaxis, infusion reactions, exacerbation of congestive heart failure, and hemolytic reactions (including methemoglobinemia and hemolysis).
