About Z68.26

It belongs to category Z68 (body mass index [BMI]), block Z68 (body mass index [BMI]) 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 Z68.2 (body mass index [BMI] 20-29, adult), Z68.26 is specifically for body mass index [BMI] 26.0-26.9, adult. Related codes cover 20.0-20.9, adult (Z68.20), 21.0-21.9, adult (Z68.21), 22.0-22.9, adult (Z68.22), 23.0-23.9, adult (Z68.23), 24.0-24.9, adult (Z68.24), 25.0-25.9, adult (Z68.25), 27.0-27.9, adult (Z68.27), 28.0-28.9, adult (Z68.28) and 1 more.
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.
The Medicare Code Editor expects this diagnosis only for patients age 15 through 124.
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 changed in FY2021 (title revised).
Before ICD-10, this condition was coded in ICD-9-CM as V85.22 (body Mass Index 26.0-26.9, adult).
