Arthritis due to Lyme disease
ICD-10 A69.23 is a billable code used to indicate a diagnosis of arthritis due to lyme disease.
Arthritis due to Lyme disease is a manifestation of Lyme borreliosis, a tick-borne illness caused by the spirochete Borrelia burgdorferi. This condition typically arises weeks to months after the initial infection, which may present with erythema migrans, flu-like symptoms, or neurological manifestations. Lyme arthritis is characterized by recurrent episodes of joint swelling and pain, most commonly affecting the knees, but can involve other joints as well. The pathophysiology involves an immune-mediated response to the spirochete, leading to synovitis and joint inflammation. Diagnosis is often confirmed through serological testing for antibodies against Borrelia species. Geographic distribution of Lyme disease is primarily in the northeastern, north-central, and Pacific coastal regions of the United States, with endemic areas including parts of Connecticut, New York, Wisconsin, and California. Awareness of the geographic prevalence is crucial for timely diagnosis and treatment, as early intervention can prevent chronic arthritis and other complications.
