Questions About M36.2Overview
What is the ICD-10 code for hemophilic arthropathy?
The ICD-10-CM code for hemophilic arthropathy is M36.2 (sometimes written as M362). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is M36.2 a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report hemophilic arthropathy on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does M36.2 group to?
On inpatient claims, hemophilic arthropathy maps to MS-DRG 554, 553, with relative weights from 0.8328 to 1.2492 depending on complications. Higher weights mean higher Medicare reimbursement.
Can M36.2 be a principal diagnosis?
No. This is a manifestation code: hemophilic arthropathy describes the manifestation of an underlying disease rather than the disease itself, so the underlying condition is sequenced first.
What is coded first with M36.2?
The Code First note reads: underlying disease, such as: factor VIII deficiency (D66); with vascular defect (D68.0-); factor IX deficiency (D67); hemophilia (classical) (D66); hemophilia B (D67); and 1 more listed in the Instructional Notes section. When one of these applies, it is sequenced before M36.2.
