S68.128S is a billable ICD-10-CM diagnosis code for partial traumatic metacarpophalangeal amputation of other finger, sequela. The 7th character S marks it as a sequela code, which reports a problem that remains after the original condition has resolved. 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. The code is exempt from POA reporting. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Injury, sequela.

S68.128S no longer risk-adjusts for Medicare Advantage: it mapped to HCC 189 under the retired CMS-HCC V24 model through payment year 2025 but maps to no category in the live V28 model. It still risk-adjusts in the PACE (CMS-HCC V22) category 189, ESRD (V21) category 189, and ESRD (V24) category 189 for payment year 2027.

From Block S60-S69 Injuries to the wrist, hand and fingers applies to 5,118 codes

From Chapter 19 (S00-T88) Injury, poisoning and certain other consequences of external causes applies to 41,187 codes
  • Use secondary code(s) from Chapter 20, External causes of morbidity, to indicate cause of injury. Codes within the T section that include the external cause do not require an additional external cause code
  • The chapter uses the S-section for coding different types of injuries related to single body regions and the T-section to cover injuries to unspecified body regions as well as poisoning and certain other consequences of external causes.

7th Character

Every code in the category takes a 7th character from the listed values, with the placeholder X filling any empty positions before it.

Questions About S68.128SOverview

Is S68.128S a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report partial traumatic metacarpophalangeal amputation of other finger, sequela on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What does the 7th character S in S68.128S mean?

The final character S makes this a sequela code: it reports a lingering problem that remains after the partial traumatic metacarpophalangeal amputation of other finger itself has resolved, not the original event.

What MS-DRG does S68.128S group to?

When partial traumatic metacarpophalangeal amputation of other finger, 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.

Is S68.128S 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 metacarpophalangeal amputation of other finger, sequela on inpatient claims. The code appears in the Injuries to the wrist, hand and fingers (S60-S69) range of the CMS exempt list.

What is the ICD-9 equivalent of S68.128S?

Under the General Equivalence Mappings, partial traumatic metacarpophalangeal amputation of other finger, sequela converts to ICD-9-CM 905.9 (late eff traumat amputat). The mapping is approximate, so confirm the match fits the documentation.

Does S68.128S risk-adjust for Medicare Advantage payment?

Not for Medicare Advantage. S68.128S mapped to HCC 189 in the retired CMS-HCC V24 model, which last determined payment in 2025, but it maps to no category in the live V28 model; see all codes that no longer risk-adjust. It still risk-adjusts in the PACE (CMS-HCC V22) category 189 (Amputation Status/Lower Limb/Amputation Complications), ESRD (V21) category 189 (Amputation Status/Lower Limb/Amputation Complications), and ESRD (V24) category 189 (Amputation Status/Lower Limb/Amputation Complications).
