Periodic Health Assessment

The Periodic Health Assessment is a screening tool used by the armed forces to evaluate the individual medical readiness of their service members. It can be conducted alone or can be combined with other individual medical readiness needs (e.g., dental exam and immunizations). Completed annually, the PHA consists of the following components for the service member:

  • A self-reported health status
  • Measurement and documentation of vitals (height, weight, blood pressure)
  • Vision screening
  • Review of current medical conditions with health care provider
  • Focused exam of identified conditions (as required)
  • Cardiovascular Screening Program Services (as required)
  • Recommendations for improvement of identified health conditions
  • Behavioral health screen
  • Laboratory services (as required)
  • Immunizations (as required)

PHAs can be performed virtually (telehealth), in-clinic, or in group events. To schedule your annual DOD PHA virtually or in-clinic, you must register with the RHRP vendor. You can register online via the RHRP portal: or call center at 1-833-782-RHRP (1-833-782-7477). Service members will have the opportunity to schedule appointments and receive notifications via text messages or email. Whenever possible, appointments are scheduled within 50 miles of the service member's residence or home station.

Eligibility for a PHA is based upon service component guidance to the RHRP.
