How to Get Prolastin-C (Alpha1-Proteinase Inhibitor) Covered by Aetna CVS Health in Michigan: Complete Coding, Prior Authorization & Appeals Guide
Answer Box: Getting Prolastin-C Covered by Aetna CVS Health in Michigan
Prolastin-C requires prior authorization from Aetna CVS Health with specific coding and documentation. Use ICD-10 code E88.01 (alpha-1 antitrypsin deficiency) with J43.9 (emphysema), HCPCS code J0256 (10mg units), and NDC 13533-0700-xx series. Submit PA forms to 888-267-3277 with AAT levels <57 mg/dL, Pi*ZZ genotype, and FEV1 30-65% predicted. If denied, you have 180 days for internal appeals and 127 days for Michigan DIFS external review. Start today: Call Aetna member services to verify coverage and request PA forms.

Coding Basics: Medical vs. Pharmacy Benefit
Prolastin-C (alpha1-proteinase inhibitor) is typically covered under the medical benefit rather than pharmacy benefit due to its infusion administration. This affects both coding and prior authorization pathways.
Medical Benefit Path (Most Common)
- HCPCS Code: J0256 (injection, alpha 1 proteinase inhibitor, 10 mg units)
- Administration: CPT codes for infusion services (96365-96368)
- Site of Care: Hospital outpatient, infusion center, or home health
- Prior Auth: Required through Aetna's medical management team
Pharmacy Benefit Considerations
Some Aetna plans may cover Prolastin-C through specialty pharmacy with different coding requirements. Verify your specific plan's pathway with CVS Caremark.
Tip: Always confirm which benefit applies to your patient's plan before submitting claims or prior authorization requests.
ICD-10 Mapping for Alpha-1 Antitrypsin Deficiency
Proper diagnosis coding is critical for Prolastin-C approval. Use these specific ICD-10 codes with supporting documentation.
| Primary Diagnosis | ICD-10 Code | Documentation Required |
|---|---|---|
| Alpha-1 Antitrypsin Deficiency | E88.01 | Genetic testing showing Pi*ZZ or equivalent severe phenotype |
| Emphysema due to AATD | J43.9 | CT scan showing panacinar emphysema, typically lower lobe |
| COPD with AATD | J44.1 | Spirometry showing obstruction (FEV1 30-65% predicted) |
Key Documentation Words
Include these specific terms in clinical notes to support coding:
- "Severe alpha-1 antitrypsin deficiency with Pi*ZZ genotype"
- "Emphysema secondary to genetic AAT deficiency"
- "Serum AAT level below protective threshold (<57 mg/dL)"
- "Progressive dyspnea and airflow limitation"
Reference: WHO ICD-10 Classification and Aetna's clinical policy bulletin.
Product Coding: HCPCS, J-Codes, and NDCs
HCPCS Code J0256 Details
J0256: Injection, alpha 1 proteinase inhibitor (human), not otherwise specified, 10 mg billable unit
NDC Codes for Prolastin-C (Grifols)
- Powder formulations:
- 1g/20mL: 13533-0700-xx
- 2g/40mL: 13533-0701-xx
- 4g/80mL: 13533-0703-xx
- 5g/100mL: 13533-0706-xx
- Liquid formulations:
- 500mg/10mL: 13533-0705-xx
- 1g/20mL: 13533-0700-xx
Units Calculation
Standard weekly dosing: 60 mg/kg body weight
- Example: 70kg patient = 4,200 mg weekly = 420 units (4,200 ÷ 10 mg per unit)
- Typical vial usage: 4-7 vials per week depending on patient weight and vial strength
Important: Always include the specific NDC code on claims with J0256 to distinguish Prolastin-C from other alpha-1 proteinase inhibitors.

Common Coding Pitfalls to Avoid
Unit Conversion Errors
Mistake: Billing 1 unit per 1g vial Correct: 1g = 1,000mg ÷ 10mg per unit = 100 units per 1g vial
Mismatched Codes
Mistake: Using J0257 (Glassia-specific code) for Prolastin-C Correct: J0256 with Prolastin-C NDC specification
Missing Documentation
Mistake: Submitting PA without genotype results Correct: Include Pi typing results showing ZZ, SZ, or null variants
Incorrect Sequencing
Mistake: Using only J43.9 without E88.01 Correct: Link emphysema (J43.9) to genetic cause (E88.01)

Appeals Process in Michigan
If Aetna CVS Health denies your Prolastin-C request, Michigan residents have specific appeal rights and timelines.
Internal Appeals with Aetna
- Timeline: 180 days from denial date
- Standard review: 30-45 days for decision
- Expedited review: 72 hours for urgent cases
- Required: Complete internal process before external review
Michigan DIFS External Review
After exhausting Aetna's internal appeals, you can request an independent external review through the Michigan Department of Insurance and Financial Services (DIFS).
Key Details:
- Timeline: 127 days from final internal denial
- Process: File online at DIFS website or call 877-999-6442
- Decision timeframe: Up to 60 days (standard), 72 hours (expedited)
- Binding decision: If approved, Aetna must comply
When to Request Expedited Review
Request expedited appeals when delays could:
- Seriously jeopardize health or ability to regain function
- Cause irreversible progression of alpha-1 antitrypsin deficiency
- Result in hospitalization for COPD exacerbations
Note: Michigan's 127-day external review window is longer than the federal 120-day standard, giving patients additional time to file.
The Counterforce Health platform can help generate evidence-based appeal letters that address specific Aetna denial reasons and align with Michigan's external review requirements.
FAQ
How long does Aetna CVS Health prior authorization take for Prolastin-C in Michigan? Standard PA decisions take 14 calendar days. Urgent requests (when health is at risk) are decided within 72 hours. Submit 60-90 days before treatment start to avoid delays.
What if Prolastin-C is non-formulary on my Aetna plan? Request a formulary exception with medical necessity documentation. Include failed trials of preferred alternatives (Zemaira, Aralast NP) and contraindications to formulary options.
Can I get an expedited appeal if Aetna denies Prolastin-C? Yes, if your physician certifies that delays would seriously jeopardize your health. Both Aetna's internal expedited review (72 hours) and Michigan DIFS expedited external review (72 hours) are available.
Do I need step therapy for Prolastin-C with Aetna CVS Health? Some Aetna plans require trials of other alpha-1 proteinase inhibitors first. Document any failures, intolerances, or contraindications to preferred alternatives in your PA request.
What's the difference between J0256 and J0257 codes? J0256 covers Prolastin-C, Aralast NP, and Zemaira (specify with NDC). J0257 is specific to Glassia. Using the wrong code can cause claim denials.
How much does Prolastin-C cost without insurance coverage? Annual costs commonly exceed $80,000-$127,000 per patient. Check with Grifols for patient assistance programs and copay support if facing coverage challenges.
