About Z48.3
Z48.3 is the ICD-10-CM diagnosis code for aftercare following surgery for neoplasm. It belongs to category Z48 (encounter for other postprocedural aftercare), 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 Z48 (encounter for other postprocedural aftercare), Z48.3 is specifically for aftercare following surgery for neoplasm. Related codes cover encounter for attention to dressings, sutures and drains (Z48.0), encounter for planned postprocedural wound closure (Z48.1), encounter for aftercare following organ transplant (Z48.2) and encounter for other specified postprocedural aftercare (Z48.8).
Use an additional code to identify the neoplasm.
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 949 (Aftercare with CC/MCC, relative weight 1.123) and DRG 950 (Aftercare without CC/MCC, relative weight 0.7664), 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 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 V58.42 (aftercare following surgery for neoplasm).
