Z13.810Encounter for screening for upper gastrointestinal disorder

Z13.810 is the ICD-10-CM diagnosis code for encounter for screening for upper gastrointestinal disorder. It belongs to category Z13 (encounter for screening for other diseases and disorders), block Z00-Z13 (persons encountering health services for examinations) 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 Z13.81 (encounter for screening for digestive system disorders), Z13.810 is specifically for encounter for screening for upper gastrointestinal disorder. Related codes cover lower gastrointestinal disorder (Z13.811) and other digestive system disorders (Z13.818).

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 V82.89 (special screening for other specified conditions).
