Mumps polyneuropathy

This code signifies a neurological complication of mumps infection, specifically the development of polyneuropathy. It indicates damage to multiple peripheral nerves caused by the mumps virus, leading to symptoms such as weakness, numbness, or pain in the affected areas.

Use this code when documentation clearly states a diagnosis of polyneuropathy directly attributed to a mumps infection. This typically occurs after the acute phase of mumps and requires a confirmed or highly suspected mumps diagnosis alongside neurological findings consistent with polyneuropathy.

• Ensure the medical record explicitly links the polyneuropathy to a mumps infection.
• Do not use this code for other neurological complications of mumps, such as meningitis or encephalitis.
• Sequence this code after the primary mumps infection code (B26.-) if the mumps is still active.
