Questions About S48.921DOverview

Is S48.921D a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report partial traumatic amputation of right shoulder and upper arm, level unspecified, subsequent encounter on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What does the 7th character D in S48.921D mean?

The final character D marks a subsequent encounter: use it for routine care while the partial traumatic amputation of right shoulder and upper arm, level unspecified is healing, after active treatment has ended.

What MS-DRG does S48.921D group to?

When partial traumatic amputation of right shoulder and upper arm, level unspecified, 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 S48.921D exempt from POA reporting?

Yes. CMS lists this code among those exempt from present on admission reporting, so hospitals do not assign a POA indicator for partial traumatic amputation of right shoulder and upper arm, level unspecified, subsequent encounter on inpatient claims. The code appears in the Injuries to the shoulder and upper arm (S40-S49) range of the CMS exempt list.

Can S48.921D be reported with S58.0?

Not as a rule. The Excludes1 note at S48, which applies to S48.921D, lists "traumatic amputation at elbow level (S58.0)". 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).
