Valid for Submission
T86.91 is a billable diagnosis code used to specify a medical diagnosis of unspecified transplanted organ and tissue rejection. The code T86.91 is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 for the submission of HIPAA-covered transactions.
The ICD-10-CM code T86.91 might also be used to specify conditions or terms like acute cellular graft rejection, chronic active graft rejection, chronic graft rejection, chronic inactive graft rejection, graft reaction and/or rejection , graft rejection, etc.
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.
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

|MS-DRG||MS-DRG Title||MCD||Relative Weight|
|919||COMPLICATIONS OF TREATMENT WITH MCC||21||1.8344|
|920||COMPLICATIONS OF TREATMENT WITH CC||21||1.0273|
|921||COMPLICATIONS OF TREATMENT WITHOUT CC/MCC||21||0.6914|
The relative weight of a diagnostic related group determines the reimbursement rate based on the severity of a patient's illness and the associated cost of care during hospitalization.
Convert T86.91 to ICD-9 Code
The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code T86.91 its ICD-9 equivalent. The approximate mapping means there is not an exact match between the ICD-10 code and the ICD-9 code and the mapped code is not a precise representation of the original code.
Information for Patients
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
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.
