- Chronic Condition
S58.022S is a billable ICD-10-CM diagnosis code for partial traumatic amputation at elbow level, left arm, 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.
S58.022S 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.
