R93.2 ICD-10-CM Code: Abnormal findings on diagnostic imaging of liver and biliary tract

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.
