What This Code Means
D48.112 is the ICD-10-CM diagnosis code for desmoid tumor, intrathoracic. A desmoid tumor located inside the chest cavity that can affect the lungs, heart, or other thoracic organs. D48.112 sits in the ICD-10-CM chapter for neoplasms (c00-d49), within the section covering neoplasms of uncertain behavior, polycythemia vera and myelodysplastic syndromes (d37-d48).
D48.112 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.
Distinguish between chest wall (D48.111) and intrathoracic (D48.112) locations based on imaging findings.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for D48.112 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
