  • Typical setting: Dermatology clinic, hospital
  • National avg charge (illustrative): $55-$120 Medicare allowed (approx. $60-$90 national Medicare average per session)
  • Most-disputed reason: Billing 17000 multiple times for the same session: only one unit of 17000 is allowed per encounter — additional lesions use add-on code 17003 (up to 14 lesions)
