What This Code Means
T86.898 is the ICD-10-CM diagnosis code for other complications of other transplanted tissue. Various other problems occur with a transplanted tissue or organ (not rejection, failure, or infection) that are not classified elsewhere. T86.898 sits in the ICD-10-CM chapter for injury, poisoning and certain other consequences of external causes (s00-t88), within the section covering complications of surgical and medical care, not elsewhere classified (t80-t88).
T86.898 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.
Use this code for complications such as graft-versus-host disease, vascular complications, or other specified issues.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for T86.898 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Use this code for complications such as graft-versus-host disease, vascular complications, or other specified issues
