A6922 - Nervous system problems caused by Lyme disease (not including the most common types)

International Classification of Diseases

Last updated: 10/3/2025

What is a ICD-10 Code?

ICD-10 (International Classification of Diseases, 10th Revision) codes are used to classify and code all diagnoses, symptoms, and procedures recorded in association with hospital care. These codes provide a standardized way to track health conditions and their treatment outcomes.

Detailed Description

This code is used when Lyme disease has affected your nervous system in ways that don't fit the more common neurological complications. Lyme disease is caused by bacteria from infected tick bites and can sometimes spread to the nervous system, causing various neurological symptoms. This particular code covers the less typical nervous system effects, which might include problems with thinking, memory, coordination, or other neurological functions. The specific symptoms can vary from person to person, but they are directly related to the Lyme disease infection affecting your nervous system.

Additional Information

This is a diagnostic code used during a follow-up hospital visit. Treatment typically involves antibiotics, and most patients improve with appropriate therapy. The 'other' designation means these are neurological complications beyond the most commonly seen ones like facial palsy or meningitis.
