G54.5 — Neuralgic amyotrophy
G54.5 is a billable, specific ICD-10-CM code for neuralgic amyotrophy. It is valid for submission on a claim.
Excludes1 — never code together
These conditions cannot occur together. Billing both on the same encounter is a denial.
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Parsonage-Aldren-Turner syndrome
- Shoulder-girdle neuritis
Other codes that can never be billed with G54.5
These codes carry an Excludes1 note pointing at G54.5. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading G54.5 alone.
- M62.5Muscle wasting and atrophy, not elsewhere classified
Risk adjustment
G54.5 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
G54.5 is named in 17 Medicare coverage policies — 17 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
