Code Classification

  • Injury, poisoning and certain other consequences of external causes
    (S00–T88)
    • Complications of surgical and medical care, not elsewhere classified
      (T80-T88)
      • Complications of transplanted organs and tissue
        (T86)

T86.91 is a billable diagnosis code used to specify a medical diagnosis of unspecified transplanted organ and tissue rejection. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

Unspecified diagnosis codes like T86.91 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Approximate Synonyms

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

  • Acute cellular graft rejection
  • Chronic active graft rejection
  • Chronic graft rejection
  • Chronic inactive graft rejection
  • Graft reaction AND/OR rejection
  • Graft rejection
  • Hyperacute graft rejection
  • Mild cellular graft rejection
  • Moderate cellular graft rejection
  • Renal tubulo-interstitial disorders in transplant rejection
  • Transplanted organ rejection

Clinical Classification

Clinical Information

  • Graft Rejection

    an immune response with both cellular and humoral components, directed against an allogeneic transplant, whose tissue antigens are not compatible with those of the recipient.
  • Graft Rejection

    rejection of transplanted tissue secondary to an immune response from the recipient.
  • Hyperacute Allograft Rejection

    an immediate rejection of transplanted tissue caused by the presence of preformed antibodies to donor human leukocyte antigens.
  • Regimen Used to Treat or Prevent Graft Rejection

    any regimen that can be used to treat or prevent graft rejection.

Coding Guidelines

The appropriate 7th character is to be added to each code from block Complications of transplanted organs and tissue (T86). Use the following options for the aplicable episode of care:

  • A - initial encounter
  • D - subsequent encounter
  • S - sequela

Patient Education


Organ Transplantation

You may need an organ transplant if one of your organs has failed. This can happen because of illness or injury. When you have an organ transplant, doctors remove an organ from another person and place it in your body. The organ may come from a living donor or a donor who has died.

The organs that can be transplanted include:

  • Heart
  • Intestine
  • Kidney
  • Liver
  • Lung
  • Pancreas

You often have to wait a long time for an organ transplant. Doctors must match donors to recipients to reduce the risk of transplant rejection. Rejection happens when your immune system attacks the new organ. If you have a transplant, you must take drugs the rest of your life to help keep your body from rejecting the new organ.
