ICD-10 Code D36.15 – Benign neoplasm of peripheral nerves and autonomic nervous system of abdomen (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D36.15 – Benign neoplasm of peripheral nerves and autonomic nervous system of abdomen
What it is
This code identifies a noncancerous tumor arising from peripheral nerves or the autonomic nervous system in the abdominal region. It indicates a benign growth, not a malignant nerve tumor.
Clinical signs
Clinical features vary; refer to documentation. Patients may have an abdominal mass, localized discomfort, or incidental imaging findings, but the diagnosis should be supported by provider documentation or pathology.
When to use this code
Use D36.15 when the record clearly documents a benign neoplasm involving abdominal peripheral nerves or autonomic nerves. It is appropriate for confirmed benign nerve sheath tumors or other nonmalignant nerve-origin lesions in the abdomen. Check documentation if the site or behavior is unclear.
Do not use for
Do not use this code for malignant nerve tumors, uncertain behavior neoplasms, or masses not documented as benign. If the lesion is in a different body site, select the code that matches that location.
Coding tip
Verify both benign behavior and abdominal nerve origin before assigning D36.15.
