ICD-10 Code D36.12 – Benign neoplasm of peripheral nerves and autonomic nervous system, upper limb, including shoulder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D36.12 – Benign neoplasm of peripheral nerves and autonomic nervous system, upper limb, including shoulder
What it is
D36.12 identifies a noncancerous tumor arising from peripheral nerves or the autonomic nervous system in the upper limb, including the shoulder. Use it when the record clearly documents a benign nerve-related neoplasm at that site.
Clinical signs
Clinical features vary; refer to documentation. Patients may have a palpable mass, localized pain, numbness, tingling, or weakness if the lesion compresses nearby structures.
When to use this code
Use D36.12 when the provider documents a benign neoplasm of a peripheral nerve or autonomic nerve in the arm, forearm, wrist, hand, or shoulder region. It may also apply after pathology, imaging, or surgical findings confirm a benign nerve tumor. If the exact site is not stated, check documentation before coding.
Do not use for
Do not use this code for malignant nerve tumors, unspecified masses, or lesions in other body regions. If the diagnosis is only suspected or the pathology is unclear, check documentation.
Coding tip
Match the code to the documented anatomic site and confirm the lesion is benign before assignment.
