All ICD10 Codes
T86Not billable, use a more specific code below

Complications of transplanted organs and tissue

In Complications of surgical and medical care, not elsewhere classified (T80-T88), chapter 19: Injury, Poisoning and Certain Other Consequences of External Causes

77 billable codes under T86: all are a CC; 32 map to HCC 221 (Heart Transplant Status/Complications), HCC 276 (Lung Transplant Status/Complications), HCC 454 (Stem Cell, Including Bone Marrow, Transplant Status/Complications) and 2 more HCCs.A CC or MCC (major CC) is a secondary diagnosis that raises the MS-DRG payment. An HCC counts toward a Medicare Advantage patient's risk score.

Use additional code: add a second code for this, listed after this one

  • code to identify other transplant complications, such as:
  • graft-versus-host disease (D89.81-)
  • malignancy associated with organ transplant (C80.2)
  • post-transplant lymphoproliferative disorders (PTLD) (D47.Z1)

Also applies, from Complications of surgical and medical care, not elsewhere classified (T80-T88)

These notes sit on T80-T88 and apply to every code under it, including T86.

Excludes2: not included here, code separately if applicable

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 T86

    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 T86

T86 can't be used on a claim. Pick a billable code below; grey headings group them.

T86 MS-DRGs

As the principal diagnosis, the billable codes under T86 group to these 25 MS-DRGs (v44.0). Which one applies depends on procedures performed, secondary diagnoses (CC/MCC), and the patient's age and discharge status.
