ICD-10 Code D36.10 – Benign neoplasm of peripheral nerves and autonomic nervous system, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D36.10 – Benign neoplasm of peripheral nerves and autonomic nervous system, unspecified
What it is
D36.10 identifies a benign, noncancerous tumor arising from peripheral nerves or the autonomic nervous system when the site is not further specified. Use it when the record confirms a benign nerve-related neoplasm but does not name the exact nerve or structure.
Clinical signs
Clinical features vary; refer to documentation. Benign nerve tumors may present as a localized mass, pain, or neurologic symptoms from compression, but the diagnosis should be supported by the provider’s documented findings.
When to use this code
Use D36.10 when the provider documents a benign neoplasm of peripheral nerves or autonomic nerves and does not specify the exact location. It also fits when pathology or imaging confirms a benign nerve tumor, but the final note remains nonspecific. If the record names a more precise site, code that instead.
Do not use for
Do not use this code for malignant nerve tumors, uncertain masses, or lesions documented only as cysts, lipomas, or other non-neural growths. Check documentation when the diagnosis is not clearly stated.
Coding tip
Look for the exact anatomic site in the operative report, pathology, or assessment before defaulting to the unspecified code.
