What This Code Means
D36.0 is the ICD-10-CM diagnosis code for benign neoplasm of lymph nodes. A noncancerous tumor that develops in the lymph nodes, which are part of the immune system. D36.0 sits in the ICD-10-CM chapter for neoplasms (c00-d49), within the section covering benign neoplasms, except benign neuroendocrine tumors (d10-d36).
D36.0 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 benign lymph node neoplasms and lymphadenopathy (enlarged lymph nodes from other causes).
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for D36.0 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Distinguish between benign lymph node neoplasms and lymphadenopathy (enlarged lymph nodes from other causes)
- •Document the specific location of the lymph node tumor if known for more precise coding
Excludes 1, Do NOT code together
- lymphangioma (D18.1)
