2027 ICD-10-CM Diagnosis Code M87.111Osteonecrosis due to drugs, right shoulder
ICD-10-CM Codes›M00–M99›M86-M90›M87
- Billable — Valid for Submission
- CC — Complication or Comorbidity
- Chronic Condition
M87.111 is a billable ICD-10-CM diagnosis code for osteonecrosis due to drugs, right shoulder. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 553 through 554. As a secondary diagnosis, it counts as a complication or comorbidity (CC) and moves an inpatient stay to a higher severity level within its MS-DRG family. It does not count, however, when the principal diagnosis is one of 217 closely related codes. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Aseptic necrosis and osteonecrosis and Drug induced or toxic related condition.
M87.111 no longer risk-adjusts for Medicare Advantage: it mapped to HCC 39 under the retired CMS-HCC V24 model through payment year 2025 but maps to no category in the live V28 model. It still risk-adjusts in the PACE (CMS-HCC V22) category 39, ESRD (V21) category 39, ESRD (V24) category 39, and RxHCC Part D (V08) category 80 for payment year 2027.

Clinical InformationClinical
Osteonecrosis
death of a bone or part of a bone, either atraumatic or posttraumatic.
Patient EducationClinical
Osteonecrosis
Osteonecrosis is a disease caused by reduced blood flow to bones in the joints. In people with healthy bones, new bone is always replacing old bone. In osteonecrosis, the lack of blood causes the bone to break down faster than the body can make enough new bone. The bone starts to die and may break down.
