About M91.3

M91.3 is the ICD-10-CM diagnosis code for Pseudocoxalgia. It belongs to category M91 (juvenile osteochondrosis of hip and pelvis), block M91-M94 (Chondropathies) 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 M91 (juvenile osteochondrosis of hip and pelvis), M91.3 is specifically for Pseudocoxalgia. Related codes cover juvenile osteochondrosis of pelvis (M91.0), juvenile osteochondrosis of head of femur [Legg-Calve-Perthes] (M91.1), coxa plana (M91.2), coxa magna (M91.4), other juvenile osteochondrosis of hip and pelvis (M91.8) and unspecified (M91.9).

To report this condition, pick the subcode that matches the documentation: M91.30 (unspecified hip), M91.31 (right hip) and M91.32 (left hip).

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