About M91.32

M91.32 is the ICD-10-CM diagnosis code for Pseudocoxalgia, left hip. 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 billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within M91.3 (Pseudocoxalgia), M91.32 is specifically for Pseudocoxalgia, left hip. Related codes cover unspecified hip (M91.30) and right hip (M91.31).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 553 (Bone Diseases and Arthropathies with MCC, relative weight 1.2494) and DRG 554 (Bone Diseases and Arthropathies without MCC, relative weight 0.8331), in MDC 08 (Diseases and Disorders of the Musculoskeletal System and Connective Tissue), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

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

Before ICD-10, this condition was coded in ICD-9-CM as 732.1 (juvenile osteochondrosis of hip and pelvis).
