ICD-10 Code D36.14 – Benign neoplasm of peripheral nerves and autonomic nervous system of thorax (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D36.14 – Benign neoplasm of peripheral nerves and autonomic nervous system of thorax
What it is
This code identifies a noncancerous tumor arising from peripheral nerves or the autonomic nervous system in the thoracic region. It indicates a benign mass in the chest area, not a malignant neoplasm.
Clinical signs
Clinical features vary; refer to documentation. Patients may have a localized thoracic mass, pain, pressure symptoms, or incidental imaging findings, depending on size and nerve involvement.
When to use this code
Use D36.14 when the provider documents a benign neoplasm of a peripheral nerve or autonomic nerve located in the thorax. Apply it for confirmed benign pathology or a documented benign nerve tumor in the chest. If the record only says “mass” or “lesion,” check documentation before coding.
Do not use for
Do not use this code for malignant nerve tumors, uncertain behavior, or nonspecific thoracic masses without a benign diagnosis. Check documentation if the site is outside the thorax.
Coding tip
Match the anatomic site carefully; D36.14 is specific to the thorax and should not replace a more precise documented nerve location.
