Questions About S63.654DOverview

Is S63.654D (Sprain of metacarpophalangeal joint of right ring finger) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report sprain of metacarpophalangeal joint of right ring finger, subsequent encounter on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What does the 7th character D in S63.654D mean?

The final character D marks a subsequent encounter: use it for routine care while the sprain of metacarpophalangeal joint of right ring finger is healing, after active treatment has ended.

What MS-DRG does S63.654D group to?

When sprain of metacarpophalangeal joint of right ring finger, subsequent encounter is the principal diagnosis on an inpatient stay, it groups to MS-DRG 950, 949, with relative weights from 0.7661 to 1.1231 depending on complications. Higher weights mean higher Medicare reimbursement.

Is S63.654D exempt from POA reporting?

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).
