Malignant neoplasm of peripheral nerves and autonomic nervous system (C47) ICD-10-CM

The C47 code range covers malignant neoplasm of peripheral nerves and autonomic nervous system with 16 ICD-10-CM diagnosis codes. 13 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.

Includes

This note appears immediately under a three character code title to further define, or give examples of, the content of the category.

Type 1 Excludes

A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Clinical Terms in This Code Range

Definitions from the National Library of Medicine for conditions coded in the C47 range.

Brachial Plexus

The large network of nerve fibers which distributes the innervation of the upper extremity. The brachial plexus extends from the neck into the axilla. In humans, the nerves of the plexus usually originate from the lower cervical and the first thoracic spinal cord segments (C5-C8 and T1), but variations are not uncommon.

Brachial Plexus Block

A blocking of NEURAL CONDUCTION in the network of nerve fibers innervating the UPPER EXTREMITY.

Brachial Plexus Neuritis

A syndrome associated with inflammation of the BRACHIAL PLEXUS. Clinical features include severe pain in the shoulder region which may be accompanied by MUSCLE WEAKNESS and loss of sensation in the upper extremity. This condition may be associated with VIRUS DISEASES; IMMUNIZATION; SURGERY; heroin use (see HEROIN DEPENDENCE); and other conditions. The term brachial neuralgia generally refers to pain associated with brachial plexus injury. (From Adams et al., Principles of Neurology, 6th ed, pp1355-6)

Brachial Plexus Neuropathies

Diseases of the cervical (and first thoracic) roots, nerve trunks, cords, and peripheral nerve components of the BRACHIAL PLEXUS. Clinical manifestations include regional pain, PARESTHESIA; MUSCLE WEAKNESS, and decreased sensation (HYPESTHESIA) in the upper extremity. These disorders may be associated with trauma (including BIRTH INJURIES); THORACIC OUTLET SYNDROME; NEOPLASMS; NEURITIS; RADIOTHERAPY; and other conditions. (From Adams et al., Principles of Neurology, 6th ed, pp1351-2)

Ganglioneuroblastoma

A moderately malignant neoplasm composed of primitive neuroectodermal cells dispersed in myxomatous or fibrous stroma intermixed with mature ganglion cells. It may undergo transformation into a neuroblastoma. It arises from the sympathetic trunk or less frequently from the adrenal medulla, cerebral cortex, and other locations. Cervical ganglioneuroblastomas may be associated with HORNER SYNDROME and the tumor may occasionally secrete vasoactive intestinal peptide, resulting in chronic diarrhea.

Horner Syndrome

A syndrome associated with defective sympathetic innervation to one side of the face, including the eye. Clinical features include MIOSIS; mild BLEPHAROPTOSIS; and hemifacial ANHIDROSIS (decreased sweating)(see HYPOHIDROSIS). Lesions of the BRAIN STEM; cervical SPINAL CORD; first thoracic nerve root; apex of the LUNG; CAROTID ARTERY; CAVERNOUS SINUS; and apex of the ORBIT may cause this condition. (From Miller et al., Clinical Neuro-Ophthalmology, 4th ed, pp500-11)

Lumbosacral Plexus

The lumbar and sacral plexuses taken together. The fibers of the lumbosacral plexus originate in the lumbar and upper sacral spinal cord (L1 to S3) and innervate the lower extremities.

Sciatic Nerve

A nerve which originates in the lumbar and sacral spinal cord (L4 to S3) and supplies motor and sensory innervation to the lower extremity. The sciatic nerve, which is the main continuation of the sacral plexus, is the largest nerve in the body. It has two major branches, the TIBIAL NERVE and the PERONEAL NERVE.

Sciatic Neuropathy

Disease or damage involving the SCIATIC NERVE, which divides into the PERONEAL NERVE and TIBIAL NERVE (see also PERONEAL NEUROPATHIES and TIBIAL NEUROPATHY). Clinical manifestations may include SCIATICA or pain localized to the hip, PARESIS or PARALYSIS of posterior thigh muscles and muscles innervated by the peroneal and tibial nerves, and sensory loss involving the lateral and posterior thigh, posterior and lateral leg, and sole of the foot. The sciatic nerve may be affected by trauma; ISCHEMIA; COLLAGEN DISEASES; and other conditions. (From Adams et al., Principles of Neurology, 6th ed, p1363)

About the C47 Code Range

The ICD-10 code C47 covers malignant tumors originating in the peripheral nerves and the autonomic nervous system. These codes specify the location of the cancer, such as the head, limbs, thorax, abdomen, pelvis, or unspecified trunk areas, helping to accurately classify these complex nerve tumors.

The section includes detailed subcodes like C47.0 for malignant neoplasms of peripheral nerves in the head, face, and neck, often referred to as malignant peripheral nerve sheath tumors or primary malignant nerve sheath neoplasms of these areas. Codes such as C47.1 and its subsets represent tumors in the upper limbs, while C47.2 and following detail lower limb involvement, including the hip. Other locations are covered by C47.3 to C47.6, identifying thorax, abdomen, pelvis, or trunk nerve malignancies. There are also codes for overlapping sites (C47.8) and unspecified locations (C47.9), which include a wide range of tumor types and synonyms like malignant Triton tumor or ganglioneuroblastoma. This classification helps medical coders and healthcare providers link clinical conditions with precise diagnosis codes for peripheral nerve cancers in various body regions.

Questions About This Page

How many billable codes are in the C47 range?

Of the 16 codes in this range, 13 are billable and valid for claim submission from October 1, 2025 through September 30, 2026. Category header codes group them but cannot be reported on claims.

What does the C47 range classify?

The range classifies malignant neoplasm of peripheral nerves and autonomic nervous system. Each code links to its own reference page with billing status, MS-DRG grouping, coding notes, and clinical information.
