Other mononeuropathies (G58) ICD-10-CM

The G58 code range covers other mononeuropathies with 5 ICD-10-CM diagnosis codes. 4 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.

Clinical Terms in This Code Range

Definitions from the National Library of Medicine for conditions coded in the G58 range.

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.

Pudendal Neuralgia

Pain associated with a damaged PUDENDAL NERVE. Clinical features may include positional pain with sitting in the perineal and genital areas, sexual dysfunction and FECAL INCONTINENCE and URINARY INCONTINENCE.

About the G58 Code Range

ICD-10 code G58 covers other mononeuropathies, a group of nerve disorders affecting single nerves outside of the common types. These codes are used for diagnosing specific nerve conditions that do not fall under other neuropathy classifications.

The G58 section includes codes such as G58.0 for intercostal neuropathy, which involves nerve pain or damage around the ribs, often known as intercostal neuralgia or postinfectious neuralgia. G58.7 represents mononeuritis multiplex, characterized by damage to multiple separate nerves often linked to conditions like vasculitis or diabetes, with synonyms like vasculitic mononeuritis multiplex or diabetic mononeuropathy aiding diagnosis. G58.8 encompasses other specified mononeuropathies, including rare or complex nerve disorders such as phrenic nerve disorders, pudendal neuralgia, or ischemic peripheral neuropathy. Lastly, G58.9 is used for unspecified mononeuropathies when the exact nerve condition is unclear but involves nerve thickening, entrapment, or palsy. Understanding these codes ensures accurate classification of various mononeuropathies for medical coding and clinical treatment.

Questions About This Page

How many billable codes are in the G58 range?

What does the G58 range classify?

The range classifies other mononeuropathies. Each code links to its own reference page with billing status, MS-DRG grouping, coding notes, and clinical information.
