CMSSource: CMS FY 2027 ICD-10-CM dataset · Effective Oct 1, 2026 – Sep 30, 2027

M97.8XXA is a billable ICD-10-CM diagnosis code for periprosthetic fracture around other internal prosthetic joint, initial encounter. The 7th character A marks it as an initial encounter code, used while the patient is receiving active treatment. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 559 through 561. 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 193 closely related codes. Coders also document this condition as fracture of bone adjacent to ankle joint prosthesis. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Fracture of the lower limb (except hip), initial encounter.
