ICD-10 Code G58.0 – Intercostal neuropathy (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G58.0 – Intercostal neuropathy
What it is
G58.0 identifies neuropathy of the intercostal nerves, which run between the ribs. Use it when documentation shows nerve pain or dysfunction affecting one or more intercostal nerves.
Clinical signs
Clinical features vary; refer to documentation. Commonly, you may see localized chest wall pain, burning, numbness, or tenderness in a band-like distribution along an intercostal space.
When to use this code
Use G58.0 when the provider documents intercostal neuropathy, intercostal neuralgia, or nerve involvement between the ribs. It is appropriate when the condition is the primary diagnosis being evaluated or treated. Check the record for the specific nerve site and cause if documented.
Do not use for
Do not use this code for generalized neuropathy, musculoskeletal chest wall pain, or pleuritic pain without nerve involvement. If documentation is unclear, check documentation before assigning G58.0.
Coding tip
Code G58.0 only when the record clearly links the symptoms to intercostal nerve pathology.
