What This Code Means
T86.822 is the ICD-10-CM diagnosis code for skin graft (allograft) (autograft) infection. An infection develops in or around a transplanted skin graft after the grafting procedure. T86.822 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).
T86.822 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.
Identify the causative organism (bacterial, fungal, viral) with an additional code if documented.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for T86.822 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Identify the causative organism (bacterial, fungal, viral) with an additional code if documented
- •Note whether the infection is localized to the graft site or has spread to surrounding tissue
