ICD-10 Code A69.22 – Other neurologic disorders in Lyme disease (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A69.22 – Other neurologic disorders in Lyme disease
What it is
A69.22 identifies neurologic complications caused by Lyme disease that do not fit a more specific neurologic Lyme code. Use it when the record documents nervous system involvement linked to Lyme infection, but the exact pattern is not otherwise classified.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings may include neuropathy, radicular pain, cranial nerve involvement, or other neurologic deficits associated with Lyme disease.
When to use this code
Use this code when the clinician documents a neurologic disorder due to Lyme disease and no more specific ICD-10-CM code applies. It is appropriate for confirmed or clearly documented Lyme-related neurologic involvement in the assessment or diagnosis. If the note only mentions Lyme disease without neurologic findings, do not assign this code.
Do not use for
Do not use it for uncomplicated Lyme disease or for neurologic symptoms without a documented Lyme connection. Check documentation if the record supports a more specific neurologic Lyme diagnosis.
Coding tip
Link the neurologic diagnosis to Lyme disease in the provider note before assigning A69.22.
