What to Ask When You Call

Before scheduling, ask the clinic three questions that determine whether the visit will be productive:

  1. Has your clinic billed insurance for LDRT for osteoarthritis before? Practices with prior billing experience know the procedure codes and have relationships with payers—this matters more than any individual insurer's written policy.
  2. Is prior authorization required? Some insurers require written approval before treatment. A clinic with experience will handle the PA process; ask whether they do.
  3. Which joints does this clinic treat with LDRT? Not every program offers LDRT for every joint. Confirm your specific joint before driving in.
