TRICARE Coverage for Medical Physics and Therapy

## Quick answer TRICARE covers physical therapy and specialized "physics-based" diagnostic services when they are medically necessary to treat a specific injury or illness. While TRICARE does not have a benefit category simply named "Physics," it heavily regulates the medical physics involved in radiation oncology (cancer treatment) and advanced diagnostic imaging like MRIs and CT scans.
## In detail In the context of TRICARE, "physics" most commonly refers to **Medical Physics** services required for therapeutic radiation and complex imaging. These services ensure that radiation doses are calculated accurately and equipment is calibrated for patient safety.
### Radiation Oncology and Medical Physics For beneficiaries undergoing cancer treatment, TRICARE covers the professional services of medical physicists. These services are typically bundled into the "Technical Component" of radiation therapy. Under 2026 guidelines, coverage includes: * **Dosimetry:** Calculations performed by a physicist to determine the exact duration and intensity of radiation. * **Treatment Planning:** Complex 3D simulations used to target tumors while sparing healthy tissue. * **Quality Assurance:** Ongoing verification that linear accelerators and other equipment meet Defense Health Agency (DHA) safety standards.
### Physical Therapy (Biophysics) TRICARE covers physical therapy to restore function or prevent disability following illness, injury, or surgery. * **Referrals:** TRICARE Prime beneficiaries usually require a referral from their Primary Care Manager (PCM). TRICARE Select beneficiaries can visit any TRICARE-authorized provider without a referral, though they will pay higher out-of-pocket costs. * **2026 Costs:** For a TRICARE Select Group A retiree, the 2026 copayment for an outpatient physical therapy visit is approximately $35–$40 per visit (check TRICARE.mil for exact regional adjustments).
### Diagnostic Imaging Physics TRICARE mandates that facilities providing advanced imaging (MRI, CT, PET scans) comply with specific physics-based accreditation standards (such as those from the American College of Radiology). The cost of the "physics" side of these tests is included in the global or technical fee for the scan.
| Service Type | TRICARE Plan | Authorization Required? | | :--- | :--- | :--- | | **Radiation Physics** | Prime & Select | Yes (Medical Necessity Review) | | **Physical Therapy** | Prime | Yes (PCM Referral) | | **Physical Therapy** | Select | No (Authorized Providers Only) | | **Diagnostic Imaging** | All | Often (Depends on specific scan type) |
## Who this applies to * **Active Duty Service Members (ADSMs):** Must receive all physics-related medical services (therapy or radiation) at Military Medical Facilities or via a coordinated referral in the civilian network (managed by **Humana Military** in the East or **TriWest** in the West). * **Retirees and Families:** Covered for medical physics as part of cancer care or rehabilitation, subject to annual deductibles and cost-shares. * **Cancer Patients:** Specifically those receiving External Beam Radiation Therapy (EBRT) or Brachytherapy. * **Recovering Patients:** Those requiring physical therapy to address biomechanical issues or injury recovery.
Common scenarios
**1. Cancer Treatment in the West Region (2026)** A retiree in California (West Region, managed by **TriWest**) is diagnosed with prostate cancer. Their treatment plan includes 20 sessions of radiation. The medical physics calculations (dosimetry) are billed as part of the specialized treatment plan. Since the retiree is on TRICARE Select, they meet their $150 individual deductible (Group A) and then pay a 25% cost-share for the contracted rate of the physics services.
**2. Physical Therapy for a Dependent (East Region)** An active duty spouse in Virginia (East Region, managed by **Humana Military**) suffers a torn ACL. Their PCM at the military clinic refers them to a civilian physical therapist. Because they are on TRICARE Prime, the "physics" of their rehabilitation—including gait analysis and therapeutic exercise—is covered with a $0 copay, provided they stay within the Humana provider network.
## Related terms * **Medical Physicist:** A healthcare professional who applies the principles of physics to the practice of medicine, primarily in radiation oncology and imaging. * **Dosimetry:** The measurement and calculation of the radiation dose received by the human body. * **T-5 Contract:** The current TRICARE contract (effective 2025) which transitioned West Region management to TriWest Healthcare Alliance. * **Medical Necessity:** A requirement for coverage stating that a service must be essential for the diagnosis or treatment of a condition. * **Technical Component:** The portion of a medical fee that covers equipment, supplies, and non-physician personnel (including physicists).
