T88.51XD ICD-10-CM Code: Hypothermia following anesthesia, subsequent encounter
T88.51XD is the authoritative medical code for Hypothermia following anesthesia, subsequent encounter. This classification is used in medical billing and clinical recording to specify the clinical criteria for hypothermia following anesthesia, subsequent encounter (ICD-10-CM T88.51XD), 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 949 — AFTERCARE WITH CC/MCC (MDC 23)
- MS-DRG 950 — AFTERCARE WITHOUT CC/MCC (MDC 23)
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.
