G13.0 — Paraneoplastic neuromyopathy and neuropathy
G13.0 is a billable, specific ICD-10-CM code for paraneoplastic neuromyopathy and neuropathy. It is valid for submission on a claim.
Risk adjustment
G13.0 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
Medicare coverage
G13.0 is named in 23 Medicare coverage policies — 20 listing it as supporting medical necessity, and 3 listing it as NOT covered. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
