M36.2Hemophilic arthropathy

M36.2 is the ICD-10-CM diagnosis code for Hemophilic arthropathy. It belongs to category M36 (systemic disorders of connective tissue in diseases classified elsewhere), block M30-M36 (systemic connective tissue disorders) 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 M36 (systemic disorders of connective tissue in diseases classified elsewhere), M36.2 is specifically for Hemophilic arthropathy. Related codes cover Dermato(poly)myositis in neoplastic disease (M36.0), arthropathy in neoplastic disease (M36.1), arthropathy in other blood disorders (M36.3), arthropathy in hypersensitivity reactions classified elsewhere (M36.4) and systemic disorders of connective tissue in other diseases classified elsewhere (M36.8).

Code first underlying disease, such as: factor VIII deficiency (D66), with vascular defect (D68.0-), factor IX deficiency (D67), hemophilia (classical) (D66) and 2 more.

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 713.2 (arthropathy associated with hematological disorders).
