G73.7Myopathy in diseases classified elsewhere

Billable / specific codeICD-10-CM

G73.7 is a billable, specific ICD-10-CM code for myopathy in diseases classified elsewhere. 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.

Code first

The underlying condition must be sequenced before this code.

  • underlying disease, such as:
  • glycogen storage disease (E74.0-)
  • hyperparathyroidism (E21.0, E21.3)
  • hypoparathyroidism (E20.-)
  • lipid storage disorders (E75.-)

Other codes that can never be billed with G73.7

These codes carry an Excludes1 note pointing at G73.7. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading G73.7 alone.

  • M63Disorders of muscle in diseases classified elsewhere

Risk adjustment

G73.7 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

G73.7 is named in 15 Medicare coverage policies 15 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
