Questions About M84.441SOverview
What is the ICD-10 code for pathological fracture, right hand, sequela?
The ICD-10-CM code for pathological fracture, right hand, sequela is M84.441S (sometimes written as M84441S). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is M84.441S (Pathological fracture, right hand) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report pathological fracture, right hand, sequela on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What does the 7th character S in M84.441S mean?
The final character S makes this a sequela code: it reports a lingering problem that remains after the pathological fracture, right hand itself has resolved, not the original event.
What MS-DRG does M84.441S group to?
When pathological fracture, right hand, 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.
Can M84.441S be reported with M48.5?
Not as a rule. The Excludes1 note at M84.4, which applies to M84.441S, lists "collapsed vertebra NEC (M48.5)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
