ICD-10 Coding and Documentation Requirements

Primary Diagnosis Code

E85.1 - Neuropathic heredofamilial amyloidosis is the primary code for hATTR polyneuropathy. This code must be clearly supported by:

  • Genetic testing showing pathogenic TTR mutation
  • Clinical documentation of polyneuropathy symptoms
  • Neurologist confirmation of hereditary ATTR amyloidosis

Supporting Documentation Words

Your medical records should include these specific terms to support E85.1 coding:

  • "Hereditary transthyretin-mediated amyloidosis"
  • "Pathogenic TTR mutation"
  • "Progressive sensorimotor polyneuropathy"
  • "Autonomic neuropathy" (if present)
  • "Familial amyloid polyneuropathy"
Tip: Ensure your neurologist's notes explicitly link the neuropathy to hereditary ATTR amyloidosis rather than using generic neuropathy terms.

Disease Staging Requirements

UnitedHealthcare requires one of these documented staging measures:

  • PND (Polyneuropathy Disability) score ≤ IIIb
  • FAP Stage 1 or 2
  • NIS (Neuropathy Impairment Score) ≥ 10 and ≤ 130

HCPCS/J-Code and NDC Information

Billing Codes for Tegsedi

  • HCPCS Codes: J3490 (unclassified drugs) or C9399 (unclassified drugs/biologicals)
  • NDC Code: 72126-0007-02 (Tegsedi 284mg/1.5mL prefilled syringe)
  • Units: Typically billed per injection (weekly dosing)

Pharmacy vs. Medical Benefit

Tegsedi is usually covered under the pharmacy benefit as a self-administered subcutaneous injection. Verify with UnitedHealthcare which benefit applies to your specific plan, as this affects the approval pathway.

Note: Claims using J3490 or C9399 will pend for manual review due to the unclassified nature of these codes.
