Intercostal neuropathy

This code describes a neurological disorder characterized by pain, numbness, or tingling along the distribution of one or more intercostal nerves. It results from damage or irritation to these nerves, which are located between the ribs. The condition often presents as a band-like pain around the chest or upper abdomen.

Use this code when documentation clearly indicates a diagnosis of intercostal neuropathy, often presenting with symptoms like localized chest wall pain, dysesthesia, or hyperesthesia in an intercostal nerve distribution. Supporting documentation should specify the neurological nature of the pain and rule out other causes of chest pain, such as cardiac or musculoskeletal issues.

• Differentiate from other chest wall pain codes (e.g., myalgia, costochondritis) which are musculoskeletal in origin.
• Look for specific physician documentation of "intercostal neuropathy," "intercostal neuralgia," or nerve impingement/damage.
• Consider sequencing this code as a primary diagnosis when it is the reason for the encounter, or as a secondary diagnosis when it's a co-morbidity.
