Other neurologic disorders in Lyme disease

This code signifies neurological manifestations of Lyme disease other than meningitis, encephalitis, or polyneuropathy. It encompasses a range of neurological complications that arise as a direct result of Borrelia burgdorferi infection affecting the central or peripheral nervous system. These can include conditions like cranial neuropathies (e.g., facial palsy), radiculopathy, or myelitis.

Use this code when documentation specifies a neurological disorder directly attributed to Lyme disease, but the specific diagnosis does not fall under meningitis, encephalitis, or polyneuropathy. This typically applies to patients with confirmed Lyme disease presenting with symptoms such as Bell's palsy, nerve root pain, or spinal cord inflammation. Documentation should clearly link the neurological finding to the Lyme infection.

• Always sequence the underlying Lyme disease code (A69.20 or A69.21) first, followed by this code.
• Do not use this code for psychiatric manifestations of Lyme disease; refer to F02.80 or F02.81.
• Ensure the medical record explicitly states the neurological condition is a direct sequela of Lyme disease, not an incidental finding.
