T88.53XS ICD-10-CM Code: Unintended awareness under general anesthesia during procedure, sequela
T88.53XS is the authoritative medical code for Unintended awareness under general anesthesia during procedure, sequela. This classification is used in medical billing and clinical recording to specify the clinical criteria for unintended awareness under general anesthesia during procedure, sequela (ICD-10-CM T88.53XS), 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 922 — OTHER INJURY, POISONING AND TOXIC EFFECT DIAGNOSES WITH MCC (MDC 21)
- MS-DRG 923 — OTHER INJURY, POISONING AND TOXIC EFFECT DIAGNOSES WITHOUT MCC (MDC 21)
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.

Is an additional code needed with T88.53XS?
Use additional code(s) to specify: code for adverse effect, if applicable, to identify drug (T41.- with fifth or sixth character 5); code for adverse effect, if applicable, to identify drug (T36-T50 with fifth or sixth character 5); code(s) to identify the specified condition resulting from the complication; code to identify devices involved and details of circumstances (Y62-Y82).
