We have a Nurse that does the measuring for shoes for diabetic patients. Normally, I would charge the A5500 "For diabetics only, fitting (including follow-up), custom preparation and supply of off-the-shelf depth-inlay shoe manufactured to accommodate multi-density insert(s), per shoe" but the shoes are provided to the patients through a special program. Our facility does not pay for the shoes. What can I charge, if anything, for the measuring for the shoes? Can I charge a nurse visit (99211)? TIA.
