Z53.8Procedure and treatment not carried out for other reasons

Z53.8 is the ICD-10-CM diagnosis code for procedure and treatment not carried out for other reasons. It belongs to category Z53 (persons encountering health services for specific procedures and treatment, not carried out), block Z40-Z53 (Encounters for other specific health care) 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 Z53, choose Z53.8 (and treatment not carried out for other reasons) only when documentation doesn't support a more specific option: and treatment not carried out because of contraindication (Z53.0), and treatment not carried out because of patient's decision for reasons of belief and group pressure (Z53.1), and treatment not carried out because of patient's decision for other and unspecified reasons (Z53.2), converted to open procedure (Z53.3) and and treatment not carried out, unspecified reason (Z53.9).

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 795 (Normal Newborn, relative weight 0.2022) and DRG 951 (Other Factors Influencing Health Status, relative weight 0.5577), in MDC 15 (Newborns and Other Neonates with Conditions Originating in the Perinatal Period) and 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 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 V64.3 (procedure not carried out for other reasons).
