Prior Authorization Letter Drafter
Draft a comprehensive prior authorization request letter for medical procedures, medications, or services. This prompt helps healthcare administrators write clear, medically justified authorization requests that address common payer denial criteria and increase the likelihood of first-pass approval.
This prompt helps healthcare administrators draft a structured prior authorization request letter using de-identified administrative and clinical context — no actual patient PHI is entered. It produces a multi-section letter covering case identification, medical necessity, clinical history summary, payer criteria alignment, and an attachments list. It is designed for medical billing specialists, authorization coordinators, and revenue cycle staff at physician practices, ambulatory surgery centers, and health systems.

Constraints
This does not constitute medical advice. Follow HIPAA guidelines. Recommend consulting qualified healthcare professionals.
Never include actual patient Protected Health Information (PHI) in prompts or outputs — use descriptive placeholders only.
Prior authorization requirements vary significantly by payer and plan — verify specific criteria with the payer before finalizing the letter.
Medical necessity determinations are clinical decisions — review with the treating provider before submission.

Uncertainty
If clinical details are insufficient to draft a complete medical necessity argument, identify the specific clinical information that must be gathered from the treating provider before the letter can be completed.
Scope
PHI-free admin only — use a BAA-compliant AI (e.g. BastionGPT or Azure OpenAI) for PHI.

The prompt
You are a senior healthcare administrator with expertise in prior authorization processes, payer requirements, and medical necessity documentation for complex insurance cases. Draft a prior authorization request letter for the following: Patient and clinical information (no actual PHI — use descriptive placeholders): - Patient type: [PATIENT_TYPE — e.g., adult, pediatric, Medicare beneficiary] - Insurance/payer: [PAYER_NAME] - Requested service/procedure: [PROCEDURE_CODE] — [PROCEDURE_DESCRIPTION] - Diagnosis codes: [DIAGNOSIS_CODES] - Treating provider: [PROVIDER_TYPE — e.g., specialist, primary care] - Facility type: [FACILITY_TYPE — e.g., outpatient surgery center, acute care hospital] Clinical context (describe without PHI): - Clinical indication: [CLINICAL_INDICATION] - Prior treatment history: [PRIOR_TREATMENTS_TRIED] - Treatment failure or contraindications: [TREATMENT_FAILURES] - Urgency level: [ROUTINE / URGENT / EMERGENCY] Draft a prior authorization letter with: ## Patient and Case Identification Header Case reference format, provider NPI, payer member ID format, date of service requested. ## Medical Necessity Statement Clear statement of medical necessity using clinical language that addresses typical payer criteria for this procedure type. ## Clinical History Summary Chronological clinical context: diagnosis, prior treatments tried, why those were insufficient, and why this procedure/service is now medically necessary. ## Supporting Criteria Documentation How this case meets the payer's typical coverage criteria or clinical guidelines (e.g., step therapy completion, failed conservative management, specialist recommendation). ## Requested Service and Setting Justification Why the requested procedure and care setting are appropriate for this case. ## Attachments List Documents to include with the submission: clinical notes, test results, prior authorization history, specialist letters. Note: Replace all placeholder clinical details with the actual patient's de-identified clinical information before submission. Never include actual PHI in AI prompts.

How to use this prompt
1
1. Gather the clinical documentation from the treating provider before drafting — the medical necessity argument requires specific clinical context, not generic procedure descriptions.
2
2. Review the payer's specific prior authorization criteria for this procedure type before drafting — addressing the payer's stated criteria directly improves first-pass approval rates.
3
3. Have the treating provider review the medical necessity section for clinical accuracy before submission.
Customization tips
Add 'This payer uses [specific criteria set — e.g., MCG Guidelines, InterQual] — draft the medical necessity argument to align with those criteria' for payers with published criteria.
For urgent authorization requests, add 'This request is urgent due to [clinical urgency] — include an urgency statement at the top of the letter and request expedited review.'
Append 'The patient has previously received this service from another provider — include the prior service history and continuity of care justification.'
Sample output
Prior Authorization Request — Lumbar Spinal Fusion (ACDF L4-L5)
Patient: 54-year-old female
Primary Diagnosis: Lumbar degenerative disc disease with radiculopathy, [ICD-10 CODE]
Requested Procedure: Posterior lumbar interbody fusion, L4-L5, [CPT CODE]
Clinical Summary:
This patient has undergone an extensive conservative treatment protocol spanning 14 months without meaningful relief. Treatment attempted includes physical therapy (24 sessions documented), chiropractic manipulation (18 visits), epidural steroid injections (3 series, bilateral), and a structured home exercise program. All modalities have been documented in the clinical record with objective functional assessments showing no sustained improvement in mobility or pain reduction.
Imaging Review:
MRI of the lumbar spine, obtained within the past 6 months, demonstrates moderate-to-severe disc space narrowing at L4-L5 with posterior disc protrusion causing significant right-sided foraminal stenosis. Nerve conduction studies confirm right L5 radiculopathy with denervation changes in the extensor hallucis longus and tibialis anterior.
Medical Necessity Justification:
Conservative management has been exhausted per the payer's clinical guidelines. The patient's functional status has deteriorated, with documented inability to perform activities of daily living, sit for more than 20 minutes, or ambulate greater than one block without significant neurological symptoms. Surgical intervention is medically necessary to prevent further neurological compromise.
Requested Review Level: Expedited (neurological urgency)
Treating Surgeon: Board-certified spine orthopedic surgeon
Anticipated Facility: Contracted in-network hospital

Frequently asked questions
Most payers require: the patient's diagnosis (ICD-10 codes), the requested procedure or service (CPT codes), medical necessity justification, evidence that less intensive treatments were tried first (step therapy), the treating provider's credentials and NPI, and supporting clinical documentation. For specialty medications, payers often require evidence of failure on preferred formulary agents and confirmation of the diagnosed condition. Review the payer's specific prior authorization criteria for the service before submitting.
Document every prior authorization request, approval, denial, and appeal in the patient's administrative record. Record the payer's authorization number, effective dates, and any service limitations. This documentation is critical for billing compliance, for supporting appeals if authorization is later denied during retrospective review, and for demonstrating medical necessity if the payer audits the claim. Create a standard workflow that ensures authorization documentation reaches both the clinical and billing teams.
