What This Code Means
D35.6 is the ICD-10-CM diagnosis code for benign neoplasm of aortic body and other paraganglia. A noncancerous tumor of the aortic body or other paraganglia, which are small hormone-producing tissues scattered throughout the body near major blood vessels. D35.6 sits in the ICD-10-CM chapter for neoplasms (c00-d49), within the section covering benign neoplasms, except benign neuroendocrine tumors (d10-d36).
D35.6 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.
Paragangliomas can occur in multiple locations; specify the exact site if documented.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for D35.6 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Paragangliomas can occur in multiple locations; specify the exact site if documented
- •Confirm benign status and document any functional symptoms (hypertension, sweating, palpitations)
