About M92.521

M92.521 is the ICD-10-CM diagnosis code for juvenile osteochondrosis of tibia tubercle, right leg. It belongs to category M92 (other juvenile osteochondrosis), 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 M92.52 (juvenile osteochondrosis of tibia tubercle), M92.521 is specifically for juvenile osteochondrosis of tibia tubercle, right leg. Related codes cover left leg (M92.522), bilateral (M92.523) and unspecified leg (M92.529).

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 was added in FY2021, effective October 1, 2020.
