A69.20
BillableLyme disease, unspecified
This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
Lyme disease is an infection spread by tick bites that can affect the joints, heart, and nervous system. This code is used when the specific type or stage of Lyme disease has not been determined or documented.
Coding Tips
- •Use more specific Lyme disease codes (A69.21 for meningitis, A69.22 for other neurologic manifestations, A69.23 for arthritis) if the clinical documentation specifies the affected body system or manifestation
- •Verify that the patient has confirmed Lyme disease diagnosis; if only suspected or ruled out, different coding may apply. Document the stage of disease when possible to support more specific coding
