Manifestation codes describe the manifestation of an underlying disease, not the disease itself, and therefore should not be used as a principal diagnosis.

Questions About M36.3Overview

What is the ICD-10 code for arthropathy in other blood disorders?

The ICD-10-CM code for arthropathy in other blood disorders is M36.3 (sometimes written as M363). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

Is M36.3 a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report arthropathy in other blood disorders on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What MS-DRG does M36.3 group to?

On inpatient claims, arthropathy in other blood disorders 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 M36.3 be a principal diagnosis?

No. This is a manifestation code: arthropathy in other blood disorders describes the manifestation of an underlying disease rather than the disease itself, so the underlying condition is sequenced first.

What is coded first with M36.3?

The Code First note reads: underlying disease, such as: disease of blood and blood-forming organs, unspecified (D75.9); other hemoglobinopathies (D58.2); thalassemia (D56.-). When one of these applies, it is sequenced before M36.3.
