A6929 - Other health problems caused by Lyme disease

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 a patient has health conditions that are caused by Lyme disease but don't fit into the more specific Lyme disease categories. Lyme disease is an infection spread by tick bites that can affect different parts of the body including joints, heart, and nervous system. This particular code covers various complications or symptoms of Lyme disease that aren't classified elsewhere, such as certain skin conditions, joint problems, or other organ involvement that results from the Lyme infection.

Additional Information

This is a diagnostic code, not a procedure code. The associated procedure classification (P6C - Minor procedures) suggests this diagnosis may be related to minor diagnostic or treatment procedures. Lyme disease can have various manifestations and may require different treatment approaches depending on which body systems are affected.
