Is D14.4 an HCC code?

No. D14.4 is a billable ICD-10-CM code but does not map to any HCC category in V28, V24, ESRD, or RxHCC.

This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).

What This Code Means

D14.4 is the ICD-10-CM diagnosis code for benign neoplasm of respiratory system, unspecified. A non-cancerous tumor in the respiratory system (lungs, airways, or related structures) that cannot be more specifically identified. D14.4 sits in the ICD-10-CM chapter for neoplasms (c00-d49), within the section covering benign neoplasms, except benign neuroendocrine tumors (d10-d36).

D14.4 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 only when the specific respiratory site cannot be determined from available documentation.

HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for D14.4 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.

Coding Tips

  • Use this code only when the specific respiratory site cannot be determined from available documentation
  • Review imaging and pathology reports to assign a more specific code (D14.0, D14.1, D14.3x) when possible
