C47Malignant neoplasm of peripheral nerves and autonomic nervous system

Non-billable headerICD-10-CM

C47 is a non-billable header ICD-10-CM code for malignant neoplasm of peripheral nerves and autonomic nervous system. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

  • Kaposi's sarcoma of soft tissue (C46.1)

Includes

Conditions this code covers.

  • malignant neoplasm of sympathetic and parasympathetic nerves and ganglia

Other codes that can never be billed with C47

These codes carry an Excludes1 note pointing at C47. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading C47 alone.

  • C72Malignant neoplasm of spinal cord, cranial nerves and other parts of central nervous system

Risk adjustment

C47 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Code to one of these instead C47

9 child codes. Green means billable.
