M1A.2 — Drug-induced chronic gout
Is M1A.2 billable?
No — M1A.2 is a non-billable header code. M1A.2 groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 48 billable codes beneath M1A.2.

Use additional code
Report an additional code alongside M1A.2 to fully describe the condition. M1A.2 is sequenced first.
- code for adverse effect, if applicable, to identify drug (T36-T50 with fifth or sixth character 5)
Excludes1 — never code together — inherited from M1A
The conditions below can never be reported together with M1A.2 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- gout NOS (M10.-)
Use additional code — inherited from M1A
Report an additional code alongside M1A.2 to fully describe the condition. M1A.2 is sequenced first.
- 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)
- Glomerular disorders in diseases classified elsewhere (N08)
Excludes2 — not included here — inherited from Chapter 13
The conditions below are not part of M1A.2, but a patient may have both at the same time. When documentation supports it, M1A.2 and the excluded code may both be reported.
- arthropathic psoriasis (L40.5-)
- certain conditions originating in the perinatal period (P04-P96)
- certain infectious and parasitic diseases (A00-B99)
- compartment syndrome (traumatic) (T79.A-)
- complications of pregnancy, childbirth and the puerperium (O00-O9A)
- congenital malformations, deformations, and chromosomal abnormalities (Q00-Q99)
- endocrine, nutritional and metabolic diseases (E00-E88)
- injury, poisoning and certain other consequences of external causes (S00-T88)
- neoplasms (C00-D49)
- symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (R00-R94)
Excludes2 — not included here — inherited from M1A
The conditions below are not part of M1A.2, but a patient may have both at the same time. When documentation supports it, M1A.2 and the excluded code may both be reported.
- acute gout (M10.-)

How long has M1A.2 existed?
M1A.2 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
