G71

G71 — Primary disorders of muscles

Non-billable headerICD-10-CM

G71 is a non-billable header ICD-10-CM code for primary disorders of muscles. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes2 — not included here, but may coexist

The excluded condition is not part of this code, but a patient can have both. You may code both.

arthrogryposis multiplex congenita (Q74.3)
metabolic disorders (E70-E88)
myositis (M60.-)

Other codes that can never be billed with G71

These codes carry an Excludes1 note pointing at G71. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading G71 alone.

E31Polyglandular dysfunction
E88.4Mitochondrial metabolism disorders
G72.3Periodic paralysis

Risk adjustment

G71 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.

Code to one of these instead G71

6 child codes. Green means billable.
