In simple words: This code indicates tuberculosis affecting the nerves, but not the brain, spinal cord, or their coverings. Symptoms can include tingling, reduced sensation, fever, headache, weakness, numbness, and mental changes.

This code represents tuberculosis that affects the nervous system, excluding the brain, spinal cord, and meninges. It includes conditions like tuberculous polyneuropathy, where multiple nerves or nerve groups are damaged.Symptoms may include paresthesia, hypoesthesia, fever, headache, focal neurological deficits, behavioral changes, paresis, numbness, and altered mental status.

Example 1: A patient presents with numbness and tingling in their extremities, along with a history of tuberculosis.After ruling out other causes, they are diagnosed with tuberculous polyneuropathy and the code A17.8 is used., A patient undergoing treatment for pulmonary tuberculosis develops cranial nerve palsy. Investigations reveal tuberculosis involvement of the cranial nerve, and A17.8 is applied., A patient with a confirmed history of TB presents with persistent peripheral neuropathy. Following diagnostic evaluation, other causes are excluded, and tuberculous neuropathy is determined to be the diagnosis, leading to the application of code A17.8.

Documentation should include evidence of tuberculosis infection (positive cultures, skin test), neurological symptoms, and imaging results (if applicable), to support the diagnosis.
