ICD-10 Code for Arthropathy

The ICD-10-CM code for arthropathy is M12.9 — Arthropathy, unspecified. This is the code the Alphabetic Index gives for arthropathy with no further qualifier, valid for FY2027 (October 1, 2026 – September 30, 2027).

BillableUnspecified

M12.9 is billable but unspecified. If the documentation names a type, site or cause, one of the more specific codes below is likely expected.

Which arthropathy code should you use?

The Alphabetic Index lists 139 codes under Arthropathy. Which one applies depends on the qualifier documented in the record — the type, site, cause, or associated condition. Find the qualifier below, then verify the code in the Tabular List before using it.
