M10 — Gout
M10 is a non-billable header ICD-10-CM code for gout. 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.
- chronic gout (M1A.-)
Use additional code
Add a secondary code to capture the detail described below.
- code to identify:
- Autonomic neuropathy in diseases classified elsewhere (G99.0)
- Calculus of urinary tract in diseases classified elsewhere (N22)
- Cardiomyopathy in diseases classified elsewhere (I43)
- Disorders of external ear in diseases classified elsewhere (H61.1-, H62.8-)
- Disorders of iris and ciliary body in diseases classified elsewhere (H22)

Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Acute gout
- Gout attack
- Gout flare
- Podagra
Other codes that can never be billed with M10
These codes carry an Excludes1 note pointing at M10. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading M10 alone.
Risk adjustment
M10 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 M10
6 child codes. Green means billable.
