Practical Information Before You Call
This is the only verified LDRT provider currently listed in District of Columbia. Before making the trip, confirm a few things:
Which joints does this clinic treat? Not every program treats every joint. Confirm your specific joint before scheduling.
Is a physician referral required? Some programs require a referring physician to initiate the process. Ask whether you need a referral from your primary care doctor or specialist first.
Has your clinic billed insurance for LDRT for osteoarthritis before? Practices with prior billing experience navigate the prior authorization process more smoothly than those treating it for the first time.
