What is the correct code assignment for intercostal neuralgia?
The current index entries under Neuralgia and Neuritis do not include a subterm for intercostal. This may lead coders to assign G58.8 Other specified mononeuropathies. However, the index entry for Neuropathy has a subterm for intercostal, which assigns G58.0 Intercostal neuropathy, which is the correct code assignment for intercostal neuralgia. Indexing improvements to this area of ICD-10-AM have been made for Seventh Edition.
