Which of the following is included in designated health services?

Designated health services encompass a variety of medical services that are specifically identified under the Stark Law due to their potential for overutilization and conflict of interest. This law aims to prevent healthcare providers from referring patients for certain services to facilities in which they have a financial interest, thus ensuring that referrals are based on medical necessity rather than financial gain.

Physical therapy services are included because they can be prone to overutilization, especially when a provider has a financial stake in the service being referred. Radiology services also fall under this category for similar reasons, given that imaging resources can be overprescribed if providers are incentivized financially to refer patients to specific imaging centers. Home health services are included as well, as these are often subject to scrutiny due to concerns that physicians may refer patients for these services based on financial interests rather than actual medical need.

Therefore, all these service types—physical therapy, radiology, and home health—are collectively recognized as designated health services under the Stark Law, making the correct answer all of the above. This classification helps maintain ethical standards in healthcare referrals and protects patients from unnecessary or potentially exploitative services.
