ICD-10 Code for Chondritis
The ICD-10-CM code for chondritis is M94.8X9 — Other specified disorders of cartilage, unspecified sites. This is the code the Alphabetic Index gives for chondritis with no further qualifier, valid for FY2027 (October 1, 2026 – September 30, 2027).
M94.8X9 is billable but unspecified. If the documentation names a type, site or cause, one of the more specific codes below is likely expected.
