About M90.862
M90.862 is the ICD-10-CM diagnosis code for osteopathy in diseases classified elsewhere, left lower leg. It belongs to category M90 (Osteopathies in diseases classified elsewhere), block M86-M90 (other osteopathies) 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 M90.86 (osteopathy in diseases classified elsewhere, lower leg), M90.862 is specifically for osteopathy in diseases classified elsewhere, left lower leg. Related codes cover right lower leg (M90.861) and unspecified lower leg (M90.869).
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 is a manifestation code, so it describes the effect of an underlying disease and can't be the principal diagnosis. Code the underlying condition first.
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 730.86 (other infections involving bone in diseases classified elsewhere, lower leg) and 731.8 (other bone involvement in diseases classified elsewhere).
