About Z48.811
Z48.811 is the ICD-10-CM diagnosis code for encounter for surgical aftercare following surgery on the nervous system. 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 Z48.81 (encounter for surgical aftercare following surgery on specified body systems), Z48.811 is specifically for encounter for surgical aftercare following surgery on the nervous system. Related codes cover sense organs (Z48.810), circulatory system (Z48.812), respiratory system (Z48.813), teeth or oral cavity (Z48.814), digestive system (Z48.815), genitourinary system (Z48.816) and skin and subcutaneous tissue (Z48.817).
The conditions in its Excludes2 note aren't part of Z48.811, but may be coded alongside it if the patient has both: encounter for surgical aftercare following surgery on the sense organs (Z48.810).
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 V58.72 (aftercare following surgery of the nervous system, NEC).
