ICD-10 Code D36.17 – Benign neoplasm of peripheral nerves and autonomic nervous system of trunk, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D36.17 – Benign neoplasm of peripheral nerves and autonomic nervous system of trunk, unspecified
What it is
This code identifies a noncancerous tumor arising from a peripheral nerve or autonomic nerve structure in the trunk, when the exact site is not further specified. Use it when the record clearly documents a benign neoplasm but does not name a more precise anatomic location.
Clinical signs
Clinical features vary; refer to documentation. Patients may have a palpable mass, localized discomfort, or symptoms from nerve compression, but the diagnosis should be supported by imaging, pathology, or a clinician’s assessment.
When to use this code
Use D36.17 when the provider documents a benign peripheral nerve or autonomic nervous system tumor in the trunk and does not specify a more exact site. It is also appropriate when the lesion is described as benign and the trunk location is confirmed, but the record remains nonspecific. Check documentation if the note uses only a rule-out diagnosis.
Do not use for
Do not use this code for malignant nerve tumors, uncertain behavior neoplasms, or lesions in a different body region. If the documentation identifies a specific nerve or site, select the more precise code instead.
Coding tip
Code the documented anatomic site as specifically as possible; use D36.17 only when the trunk location is confirmed and no further detail is available.
