ICD-10 Code D36.16 – Benign neoplasm of peripheral nerves and autonomic nervous system of pelvis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D36.16 – Benign neoplasm of peripheral nerves and autonomic nervous system of pelvis
What it is
This code identifies a noncancerous growth arising from peripheral nerves or the autonomic nervous system in the pelvic region. It is used when the record clearly documents a benign neoplasm in that anatomic site.
Clinical signs
Clinical features vary; refer to documentation. Patients may have a palpable pelvic mass, localized pain, pressure symptoms, or incidental imaging findings, but the diagnosis should be supported by clinician documentation or pathology.
When to use this code
Use D36.16 when the provider documents a benign tumor of a peripheral nerve or autonomic nerve structure in the pelvis. It may be supported by imaging, biopsy, or operative findings that specify benign behavior and pelvic location.
Choose this code only when the site is pelvic and the neoplasm is clearly described as benign. If the record lists a nerve tumor without confirming location or behavior, check documentation before assigning the code.
Do not use for
Do not use this code for malignant neoplasms, uncertain behavior, or lesions in non-pelvic nerve sites. Check documentation if the record only says “mass,” “tumor,” or “nerve lesion” without benign confirmation.
Coding tip
Verify both behavior and anatomic site in the operative note, pathology report, or assessment before coding.
