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, Documentation & Prescriber Requirements

Prior Authorization

Prior authorization required

Prior authorization is recommended/required for prescription benefit coverage of Rivfloza; initial approvals are for 6 months and continuation approvals are for 1 year.

Documentation Required

Documentation requirements

Documentation (chart notes, laboratory tests, claims, etc.) is required to confirm AGXT genetic mutation, current eGFR, urinary and/or plasma oxalate measures, and evidence of continued benefit for reauthorization; reauthorization does not require resubmission of prior documentation except for documentation of continued benefit (most recent within the past 6 months).

Documentation Required

Prescriber specialty requirement

Rivfloza must be prescribed by or in consultation with a nephrologist or urologist.

Background and Indication

Rivfloza (nedosiran) is an LDHA-directed small interfering RNA indicated to lower urinary and plasma oxalate levels in PH1 patients aged ≥ 9 years with relatively preserved kidney function.

Primary Hyperoxaluria Type 1 is a rare autosomal recessive disorder caused by mutations in the AGXT gene leading to oxalate overproduction; accumulation of calcium oxalate causes nephrocalcinosis, renal stones, and renal impairment. Liver transplantation is the only curative intervention as it corrects the underlying enzymatic defect.
