About Z98.0

Z98.0 is the ICD-10-CM diagnosis code for intestinal bypass and anastomosis status. It belongs to category Z98 (other postprocedural states), 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 Z98 (other postprocedural states), Z98.0 is specifically for intestinal bypass and anastomosis status. Related codes cover arthrodesis status (Z98.1), presence of cerebrospinal fluid drainage device (Z98.2), post therapeutic collapse of lung status (Z98.3), cataract extraction status (Z98.4), sterilization status (Z98.5), angioplasty status (Z98.6) and other specified postprocedural states (Z98.8).

The conditions in its Excludes2 note aren't part of Z98.0, but may be coded alongside it if the patient has both: bariatric surgery status (Z98.84), gastric bypass status (Z98.84) and obesity surgery status (Z98.84).

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 V45.3 (intestinal bypass or anastomosis status).
