ICD-10 code for tophi gout

The ICD-10-CM code for tophi gout is M1A.9 (Chronic gout, unspecified).

Within M1A, choose M1A.9 (unspecified) only when documentation doesn't support a more specific option: idiopathic chronic gout (M1A.0), Lead-induced chronic gout (M1A.1), drug-induced chronic gout (M1A.2), due to renal impairment (M1A.3) and other secondary chronic gout (M1A.4).

Codes in this range require a 7th character: 0 for without tophus (tophi) and 1 for with tophus (tophi). Use placeholder "X" characters to fill any empty positions before the 7th character.

Use an additional 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) and 1 more.
