Inclusion terms

Alternative wordings a physician may use in the chart for this same code.

  • Inflammatory myopathy NOS

Excludes1 inherited from the categories above G72.49

These are not written on G72.49, but they bind it: a note on a category applies to every code beneath it. Billing G72.49 with anything listed here is a denial.

Written on G72 Other and unspecified myopathies

  • arthrogryposis multiplex congenita (Q74.3)
  • dermatopolymyositis (M33.-)
  • ischemic infarction of muscle (M62.2-)
  • myositis (M60.-)
  • polymyositis (M33.2.-)

Risk adjustment

G72.49 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

G72.49 is named in 24 Medicare coverage policies 24 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
