I have done Chiropractic billing for several years but my office is expanding and has hired a physical therapist as well. Billing for PT is new to me. I know there has been some changes to PT new patient visits CPT codes last year. Can anyone clarify for me what codes you bill for the different levels of new patient visits? Are any modifiers needed for PT exams? If so, what ones? Thank you! (Not for medicare billing, this will be for commercial insurance plans)
