    OpenPayer is powered by Trek Health's payer performance platform. Trek continuously ingests, validates, and normalizes Transparency in Coverage data alongside payer policies and other commercial payer data to create a structured payer intelligence foundation. OpenPayer uses this foundation to deliver personalized search results, dynamically generated policy pages, and tailored policy monitoring based on each user's payers, specialties, billing codes, and areas of interest. The same intelligence powers broader payer performance workflows, including reimbursement benchmarking, contract evaluation, payer negotiations, and financial decision-making.

    Background and Context

    Use of other biologic agents in combination is specifically excluded for certain products in this policy. For Bimzelx and Velsipity the initial approval language requires the medication to be NOT used in combination with any other biologic agent, and the Commissioner’s selections reiterate that combination biologic therapy is not permitted. Prior authorization decisions may be denied if combination biologic use is documented or not explicitly ruled out in the submitted documentation.

    Quantity/Duration: Initial approval duration 6 months; renewal 1 year; quantity limit 2 mL per 28 days

    Renewal requires documentation of response compared to baseline

    Prior Authorization

    Class‑level prior authorization for non‑preferred agents

    Agents in a drug class that are not selected as preferred will be considered non‑preferred and require prior authorization.

    • DMS selects preferred agents; non‑preferred agents require PA.
    • At least two or three unique chemical entities should be preferred per class depending on class guidance.
    Prior Authorization

    PA required for non‑preferred and new chemical entities

    Any agent not selected as preferred, and any new chemical entity in a class, requires prior authorization until reviewed by the P&T Committee.

    • New chemical entities in listed classes (e.g., Hepatitis C, Macrolides, Oxazolidinones, Tetracyclines) require PA until P&T review.
    Step Therapy

    Required prior therapy (step requirements before approval)

    Documented trial and failure of specified prior therapies is required before approval: Vowst requires completion of at least 3 full antibiotic courses (including two or more guideline agents); Bimzelx and Velsipity require trial/failure of conventional systemic therapies and trial/failure of preferred cytokine/CAM antagonists.

    • Vowst: ≥3 full courses of antibiotic treatment with two or more guideline agents (e.g., oral vancomycin, fidaxomicin, oral metronidazole).
    • Bimzelx (psoriasis): trial/failure ≥3 months of ≥1 conventional therapy (e.g., methotrexate, cyclosporine, acitretin) and 3‑month trial/failure/intolerance/contraindication to ≥1 preferred cytokine or CAM antagonist.
    • Velsipity (UC): trial/failure of ≥1 conventional therapy OR high‑risk designation, and 3‑month trial/failure/intolerance/contraindication to ≥1 preferred cytokine or CAM antagonist.
    Step Therapy

    Ulcerative colitis: conventional therapy and preferred biologic trial required

    For Mirkizumab‑mrkz (UC) initial approval, the patient must have trial and failure of ≥1 conventional therapy (5‑ASA, steroids, or immunosuppressant) or be high‑risk for complications, and must have trial/failure/intolerance/contraindication to ≥1 preferred cytokine or CAM antagonist.

    • Conventional therapies: oral/rectal 5‑ASA agents, oral/rectal steroids, or immunosuppressants (e.g., azathioprine, mercaptopurine).
    • Preferred cytokine/CAM antagonist trial: 3‑month trial and failure or documented contraindication/intolerance.
    Step Therapy

    Phosphate binders: trial of ≥2 preferred binders required before Tenapanor

    Tenapanor (Xphozah) requires a documented trial and failure, contraindication, intolerance, or inadequate response to at least two preferred phosphate binders prior to approval.

    • Patient must be on dialysis with elevated serum phosphorus and have tried ≥2 preferred phosphate binders without adequate response or with intolerance/contraindication.
    Note

    No other explicit step therapy requirements stated

    No additional explicit step therapy requirements beyond those specified for individual products are detailed in these sections.

    • Refer to individual product criteria for product‑specific step requirements.
    Documentation Required

    Required documentation for PA and renewals

    Providers must submit documentation that supports diagnosis, prescriber specialty or consultation, prior treatment trials/failures, and timing of prior antibiotic therapy (for Vowst); renewals must include documentation of clinical response compared to baseline.

    • For Vowst initial requests: documentation of ≥3 prior antibiotic courses, timing that initiation is 48–96 hours after last antibiotic, and evidence of bowel cleansing ≥8 hours prior to first dose.
    • For renewals: progress notes demonstrating response compared to baseline (e.g., symptom improvement, PASI, stool testing as specified).
    Documentation Required

    Renewal: documentation of clinical response required

    Renewal requests must include progress notes documenting response to therapy compared with baseline to support continued coverage.

    • Examples: symptom improvement measures, PASI change for psoriasis, or stool testing/clinical response for CDI and UC.
    Documentation Required

    Specialist prescribing or documented consultation required

    Initial approvals for certain agents require that the prescriber be a specialist (e.g., gastroenterologist for Vowst/Mirkizumab/Velsipity) or that treatment be documented as in consultation with the relevant specialist.

    • Vowst: prescribed by or in consultation with a gastroenterologist or infectious disease specialist.
    • UC agents (Velsipity, Mirkizumab): prescribed by or in consultation with a gastroenterologist or other UC specialist.
    Denial Risk

    Denial triggers: missing diagnosis, specialist, prior trials, or Vowst timing/prep

    Prior authorization requests may be denied for missing or insufficient documentation of diagnosis, lack of required specialist prescribing/consultation, failure to document required prior antibiotic or conventional/biologic therapy trials, missing timing requirements for Vowst (initiation 48–96 hours after antibiotics), or missing bowel cleansing prior to Vowst.

    • Specific Vowst denial triggers: absent documentation of ≥3 prior antibiotic courses, incorrect timing of initiation, or no bowel prep documented.
    • For biologic/UC agents: absent documentation of required conventional or preferred biologic trials, or lack of specialist involvement.
    Denial Risk

    Prohibited combination therapy — do not combine biologics

    Requests for use of these agents in combination with another biologic agent are explicitly not permitted and may result in denial.

    • Bimzelx and Velsipity criteria explicitly state 'NOT used in combination with any other biologic agent.'
    • Mirkizumab/UC criteria also state not to be used in combination with another biologic.
    Denial Risk

    Denial risk: missing phosphate binder trials for Tenapanor

    If documentation of trial/failure, contraindication, intolerance, or inadequate response to at least two preferred phosphate binders is not provided for dialysis patients with hyperphosphatemia, the Tenapanor request may be denied.

    • Ensure records show trials of ≥2 preferred phosphate binders and reasons for failure/intolerance if applicable.
    Prior Authorization

    Non‑preferred agent requests require PA and supporting justification

    Requests for agents not selected as preferred will be processed as non‑preferred and require PA; absence of justification or required step therapy documentation for non‑preferred agents increases the risk of denial.

    • Provide documented failure/intolerance/contraindication to preferred agents where required.
    Prior Authorization

    New chemical entities: PA required until P&T Committee review

    New chemical entities in listed classes require prior authorization until reviewed by the P&T Committee; submit PA documentation accordingly until P&T status changes.

    • Examples: new entries in Hepatitis C, Macrolides/Ketolides, Oxazolidinones, and Tetracyclines classes require PA until committee review.
