Final answer:
Medicare Part B now covers acupuncture for chronic lower back pain under certain conditions, reflecting an inclusion of alternative treatments in the Medicare program.
Step-by-step explanation:
The question 'Medicare part B covers acupuncture' can be answered as true or false. To clarify, Medicare Part B is indeed an optional insurance program that covers physician services, medical tests, and outpatient visits, including some preventative services and supplies. Originally, Medicare Part B did not cover acupuncture. However, more recently, Medicare has expanded coverage to include acupuncture for chronic lower back pain under certain conditions. This represents a shift in policy to include alternative forms of treatment, such as acupuncture, which is known for providing pain relief without the need for medication.
