Prior authorization documentation that holds up to payer scrutiny.

Prior authorization denials are rarely about the test itself. They are about how clinical necessity is documented.

Cellarian generates the documentation payers expect to see — before prior authorization is submitted.

How Cellarian supports prior authorization

Cellarian:

  • Identifies when prior authorization is required

  • Applies payer-specific documentation rules

  • Generates patient-specific medical necessity justification

  • Prepares documentation for physician review and signature

This reduces delays, resubmissions, and preventable denials.

Prior authorization for toxicology testing

Toxicology prior authorization often fails due to:

  • Generic clinical language

  • Lack of clinical risk assessment 

  • Lack of medication list or screen results

  • Inappropriate ICD-10 coding

  • No Date of Service specific clinical context

  • Not meeting payer-specific testing guidelines 

  • Misalignment with payer frequency limits

Cellarian generates documentation that:

  • Reflects the patient’s clinical history & ICD-10 coding

  • Aligns with payer medical necessity criteria

  • Supports appropriate test selection

Prior authorization for molecular testing

Molecular testing faces increasing payer scrutiny, particularly for panel-based testing.

Cellarian supports prior authorization for:

  • Respiratory pathogen testing

  • UTI panels

  • STI testing

  • Women’s health testing

  • Wound testing

Documentation is generated based on patient symptoms, risk factors, and clinical context — not templates.
