K91.5 ICD-10-CM Code: Postcholecystectomy syndrome
K91.5 is the authoritative medical code for Postcholecystectomy syndrome. This classification is used in medical billing and clinical recording to specify the clinical criteria for postcholecystectomy syndrome (ICD-10-CM K91.5), ensuring healthcare documentation aligns with current federal coding standards.
Billing Status: YES. This is a valid, specific, and billable ICD-10-CM reference.
Inpatient Payment Groups (MS-DRG)
MS-DRGs this diagnosis helps define, as principal or secondary, per the CMS ICD-10-CM/PCS MS-DRG Definitions Manual v43.0 (FY2026), Appendix B.
- MS-DRG 444 — DISORDERS OF THE BILIARY TRACT WITH MCC (MDC 07)
- MS-DRG 445 — DISORDERS OF THE BILIARY TRACT WITH CC (MDC 07)
- MS-DRG 446 — DISORDERS OF THE BILIARY TRACT WITHOUT CC/MCC (MDC 07)
A diagnosis appearing in a group's logic does not by itself determine the DRG assigned to a stay; the grouper uses the full claim.
Code Set: Valid FY2026 and FY2027. FY2026 took effect October 1, 2025.
