Questions About M84.611SOverview
What is the ICD-10 code for pathological fracture in other disease, right shoulder, sequela?
The ICD-10-CM code for pathological fracture in other disease, right shoulder, sequela is M84.611S (sometimes written as M84611S). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is M84.611S (Pathological fracture in other disease, right shoulder) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report pathological fracture in other disease, right shoulder, sequela on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What does the 7th character S in M84.611S mean?
The final character S makes this a sequela code: it reports a lingering problem that remains after the pathological fracture in other disease, right shoulder itself has resolved, not the original event.
What MS-DRG does M84.611S group to?
When pathological fracture in other disease, right shoulder, sequela is the principal diagnosis on an inpatient stay, it groups to MS-DRG 559, 561, 560, with relative weights from 0.8258 to 1.8087 depending on complications. Higher weights mean higher Medicare reimbursement.
