Outpatient physical therapy is covered by Medicare Part B. Medicare pays 80% of the Medicare-approved charges, while the patient is responsible for a small annual deductible ($183 for 2017), and a 20% coinsurance (typically $25-$30) per visit. If the patient has Medicare supplement insurance, then it will cover the patient's share subject to the plan's benefits. Although Medicare has a target limit on its annual coverage of therapy services, including outpatient physical therapy, this limit can be extended if the therapy is rendered by a Medicare certified facility, and if the therapy is medically necessary (i.e. if it is prescribed by a physician, and if the physician certifies the treatment plan).
