Valid for Submission
G58.9 is a billable diagnosis code used to specify a medical diagnosis of mononeuropathy, unspecified. The code G58.9 is valid during the fiscal year 2021 from October 01, 2020 through September 30, 2021 for the submission of HIPAA-covered transactions.
The ICD-10-CM code G58.9 might also be used to specify conditions or terms like ischemic neuropathy, mononeuritis, mononeuropathy, nerve entrapment due to scar, nerve palsy , peripheral nerve thickening, etc.
Unspecified diagnosis codes like G58.9 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.
Index to Diseases and Injuries
The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10 code(s). The following references for the code G58.9 are found in the index:
- - Atrophy, atrophic (of)
- - Irritation
- - Mononeuritis - G58.9
- - Mononeuropathy - G58.9
- - Neuronitis - G58.9
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Ischemic neuropathy
- Nerve entrapment due to scar
- Nerve palsy
- Peripheral nerve thickening
- Polyneuropathy and mononeuropathy
- DIABETIC NEUROPATHIES-. peripheral autonomic and cranial nerve disorders that are associated with diabetes mellitus. these conditions usually result from diabetic microvascular injury involving small blood vessels that supply nerves vasa nervorum. relatively common conditions which may be associated with diabetic neuropathy include third nerve palsy see oculomotor nerve diseases; mononeuropathy; mononeuropathy multiplex; diabetic amyotrophy; a painful polyneuropathy; autonomic neuropathy; and thoracoabdominal neuropathy. from adams et al. principles of neurology 6th ed p1325
- MONONEUROPATHIES-. disease or trauma involving a single peripheral nerve in isolation or out of proportion to evidence of diffuse peripheral nerve dysfunction. mononeuropathy multiplex refers to a condition characterized by multiple isolated nerve injuries. mononeuropathies may result from a wide variety of causes including ischemia; traumatic injury; compression; connective tissue diseases; cumulative trauma disorders; and other conditions.
- MEDIAN NEUROPATHY-. disease involving the median nerve from its origin at the brachial plexus to its termination in the hand. clinical features include weakness of wrist and finger flexion forearm pronation thenar abduction and loss of sensation over the lateral palm first three fingers and radial half of the ring finger. common sites of injury include the elbow where the nerve passes through the two heads of the pronator teres muscle pronator syndrome and in the carpal tunnel carpal tunnel syndrome.
- RADIAL NEUROPATHY-. disease involving the radial nerve. clinical features include weakness of elbow extension elbow flexion supination of the forearm wrist and finger extension and thumb abduction. sensation may be impaired over regions of the dorsal forearm. common sites of compression or traumatic injury include the axilla and radial groove of the humerus.
- PERONEAL NEUROPATHIES-. disease involving the common peroneal nerve or its branches the deep and superficial peroneal nerves. lesions of the deep peroneal nerve are associated with paralysis of dorsiflexion of the ankle and toes and loss of sensation from the web space between the first and second toe. lesions of the superficial peroneal nerve result in weakness or paralysis of the peroneal muscles which evert the foot and loss of sensation over the dorsal and lateral surface of the leg. traumatic injury to the common peroneal nerve near the head of the fibula is a relatively common cause of this condition. from joynt clinical neurology 1995 ch51 p31
- FEMORAL NEUROPATHY-. disease involving the femoral nerve. the femoral nerve may be injured by ischemia e.g. in association with diabetic neuropathies nerve compression trauma collagen diseases and other disease processes. clinical features include muscle weakness or paralysis of hip flexion and knee extension atrophy of the quadriceps muscle reduced or absent patellar reflex and impaired sensation over the anterior and medial thigh.
Convert G58.9 to ICD-9 Code
The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code G58.9 its ICD-9 equivalent. The approximate mapping means there is not an exact match between the ICD-10 code and the ICD-9 code and the mapped code is not a precise representation of the original code.
Information for Patients
Peripheral Nerve Disorders
Also called: Neuritis, Peripheral neuritis, Peripheral neuropathy
Your peripheral nerves are the ones outside your brain and spinal cord. Like static on a telephone line, peripheral nerve disorders distort or interrupt the messages between the brain and the rest of the body.
There are more than 100 kinds of peripheral nerve disorders. They can affect one nerve or many nerves. Some are the result of other diseases, like diabetic nerve problems. Others, like Guillain-Barre syndrome, happen after a virus infection. Still others are from nerve compression, like carpal tunnel syndrome or thoracic outlet syndrome. In some cases, like complex regional pain syndrome and brachial plexus injuries, the problem begins after an injury. Some people are born with peripheral nerve disorders.
Symptoms often start gradually, and then get worse. They include
- Burning or tingling
- Muscle weakness
- Sensitivity to touch
Treatment aims to treat any underlying problem, reduce pain and control symptoms.
