M95.1Cauliflower ear

M95.1 is the ICD-10-CM diagnosis code for Cauliflower ear. It belongs to category M95 (other acquired deformities of musculoskeletal system and connective tissue), block M95 (other disorders of the musculoskeletal system and connective tissue) and chapter 13 (diseases of the musculoskeletal system and connective tissue). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

Within M95 (other acquired deformities of musculoskeletal system and connective tissue), M95.1 is specifically for Cauliflower ear. Related codes cover acquired deformity of nose (M95.0), other acquired deformity of head (M95.2), acquired deformity of neck (M95.3), acquired deformity of chest and rib (M95.4), acquired deformity of pelvis (M95.5), other specified acquired deformities of musculoskeletal system (M95.8) and acquired deformity of musculoskeletal system, unspecified (M95.9).

To report this condition, pick the subcode that matches the documentation: M95.10 (unspecified ear), M95.11 (right ear) and M95.12 (left ear).

The conditions in its Excludes2 note aren't part of M95.1, but may be coded alongside it if the patient has both: other acquired deformities of ear (H61.1).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
