Is D36.1 a billable ICD-10-CM code?

No. D36.1 is a non-billable header code. Code to a higher level of specificity using one of its child codes.

Where does D36.1 sit in the tabular list?

Neoplasms (C00-D49), in the block Benign neoplasms, except benign neuroendocrine tumors (D10-D36).

What cannot be coded together with D36.1?

D36.1 carries Excludes1 notes, which means the conditions they list can never be coded together with it on the same encounter.

D36.1

D36.1 — Benign neoplasm of peripheral nerves and autonomic nervous system

Non-billable headerICD-10-CM

D36.1 is a non-billable header ICD-10-CM code for benign 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.

benign neoplasm of peripheral nerves of orbit (D31.6-)
neurofibromatosis (Q85.0-)

Other codes that can never be billed with D36.1

These codes carry an Excludes1 note pointing at D36.1. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading D36.1 alone.

D21Other benign neoplasms of connective and other soft tissue
D33Benign neoplasm of brain and other parts of central nervous system

Risk adjustment

D36.1 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 history

D36.1 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.

Code to one of these instead D36.1

8 child codes. Green means billable.
