Ben neoplm of prph nrv & autonm nrv sys, upr lmb, inc shldr

This code signifies the presence of a non-cancerous growth originating from the peripheral nerves or the autonomic nervous system specifically located within the upper extremity, encompassing the shoulder region. These benign neoplasms can manifest as nerve sheath tumors, such as schwannomas or neurofibromas, affecting nerve function or causing compressive symptoms.

Apply this code when documentation clearly identifies a benign tumor of a peripheral nerve or autonomic nerve within the arm, forearm, hand, or shoulder. Supporting documentation typically includes pathology reports confirming benignity, imaging studies (MRI, ultrasound) characterizing the lesion, and physician notes detailing its location and nature.

• Ensure the documentation explicitly states "benign" to differentiate from malignant or uncertain behavior neoplasms.
• Verify the precise anatomical location within the upper limb; avoid using this code for trunk or lower limb involvement.
• Distinguish from D48.2 (Neoplasm of uncertain behavior of peripheral nerves and autonomic nervous system) if benignity is not definitively established.
