Prior Authorization Requirements

Aetna CVS Health's standard prior authorization criteria for Procysbi typically include:

Required Documentation

  • Confirmed diagnosis of nephropathic cystinosis (ICD-10: E72.04)
  • Prescriber qualification: Board-certified nephrologist, geneticist, or physician experienced in rare metabolic disorders
  • Step therapy documentation: Evidence of immediate-release cysteamine (Cystagon) failure, intolerance, or contraindication
  • WBC cystine monitoring plan: Target levels <1 nmol half-cystine/mg protein every 3-4 months
  • Specialty pharmacy attestation: Confirmation of dispensing through approved specialty pharmacy
Tip: Gather all documentation before starting the PA process. Missing information is the most common cause of delays.

Step Therapy Requirements

Most Aetna plans require documented trial of immediate-release cysteamine (Cystagon) before approving Procysbi, unless contraindicated. Acceptable reasons for step therapy exception:

  • Intolerance: Severe nausea, vomiting, or other documented adverse effects
  • Inadequate response: Persistently elevated WBC cystine levels despite adherence
  • Contraindications: Medical reasons preventing Cystagon use
  • Adherence issues: Documented problems with frequent dosing schedule

Common Denial Reasons & How to Fix Them

Denial Reason How to Overturn
"Not medically necessary" Submit WBC cystine levels, genetic testing, specialist notes confirming nephropathic cystinosis
"Step therapy not met" Document Cystagon trial with dates, doses, adverse effects, or clinical rationale for contraindication
"Non-formulary drug" Request formulary exception with medical necessity letter and peer-reviewed evidence
"Quantity limits exceeded" Provide dosing rationale based on patient weight/BSA and FDA prescribing information

Dear Medical Director,

I am requesting coverage for PROCYSBI (cysteamine bitartrate delayed-release)

elevated WBC cystine levels of [X] nmol half-cystine/mg protein (normal <0.2).

The patient previously trialed immediate-release cysteamine (Cystagon) for

PROCYSBI's delayed-release formulation offers improved tolerability and

How much does Procysbi cost without insurance? Cash prices vary widely but typically range in the high four- to five-figure monthly range. Always explore manufacturer assistance programs and specialty pharmacy discount options.
