About Z72.823

Z72.823 is the ICD-10-CM diagnosis code for risk of suffocation (smothering) under another while sleeping. It belongs to category Z72 (problems related to lifestyle), block Z69-Z76 (persons encountering health services in other circumstances) 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 Z72.82 (problems related to sleep), Z72.823 is specifically for risk of suffocation (smothering) under another while sleeping. Related codes cover sleep deprivation (Z72.820) and inadequate sleep hygiene (Z72.821).

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 was added in FY2023, effective October 1, 2022.
