About Z92.83
Z92.83 is the ICD-10-CM diagnosis code for personal history of failed moderate sedation. It belongs to category Z92 (personal history of medical treatment), block Z77-Z99 (persons with potential health hazards related to family and personal history and certain conditions influencing health status) and chapter 21 (factors influencing health status and contact with health services). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.
Within Z92.8 (personal history of other medical treatment), Z92.83 is specifically for personal history of failed moderate sedation. Related codes cover personal history of extracorporeal membrane oxygenation (ECMO) (Z92.81), status post administration of tPA (rtPA) in a different facility within the last 24 hours prior to admission to current facility (Z92.82), personal history of unintended awareness under general anesthesia (Z92.84), personal history of cellular therapy (Z92.85), personal history of gene therapy (Z92.86) and personal history of other medical treatment (Z92.89).
The conditions in its Excludes2 note aren't part of Z92.83, but may be coded alongside it if the patient has both: failed moderate sedation during procedure (T88.52).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
In MS-DRG v44.0, it is part of the grouping logic for DRG 951 (Other Factors Influencing Health Status, relative weight 0.5577), in MDC 23 (Factors Influencing Health Status and Other Contacts with Health Services), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
It is not acceptable as the principal diagnosis for an inpatient stay; it may be reported as a secondary diagnosis.
It is exempt from present-on-admission (POA) reporting, so no POA indicator is required.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
Before ICD-10, this condition was coded in ICD-9-CM as V15.80 (personal history of failed moderate sedation).
