Official coding guidelines

From the ICD-10-CM Official Guidelines for Coding and Reporting, FY 2027 (CMS and NCHS). Links open the PDF at the right page.

  • Section I.C.19.g Complications of care (page 85), covers T80

    Use T86 plus a code for the complication only when it affects transplanted organ function. Body system complication codes are sequenced first unless indexed to a T code, and device pain also gets G89.18 or G89.28.

Read Section I.C.19 (page 77)

All codes under T80

T80 can't be used on a claim. Pick a billable code below; grey headings group them.

T80 MS-DRGs

As the principal diagnosis, the billable codes under T80 group to these 24 MS-DRGs (v44.0). Which one applies depends on procedures performed, secondary diagnoses (CC/MCC), and the patient's age and discharge status.
