What 97024 covers
Diathermy applies high-frequency electromagnetic energy to generate heat in targeted tissues. Physical therapists and other rehabilitation professionals may use microwave or another diathermy method as part of care for musculoskeletal pain, muscle spasm, or joint stiffness. Treatment is typically provided in an outpatient rehabilitation setting, with the applicator positioned for the area being treated.
Report 97024 when diathermy is the modality delivered, rather than infrared heat, ultrasound, or a surface hot pack. This is an untimed modality: report one unit for the service, not units accumulated in 15-minute increments. Documentation should identify the treated area, the diathermy modality, and the clinical purpose of treatment. The professional component modifier does not apply. Under the therapy multiple procedure payment reduction, practice expense is reduced for the second and later therapy units on the same day.

97024 billing questions
How does 97024 differ from infrared therapy?
97024 is for diathermy, such as microwave energy used to produce therapeutic heat. Use 97026 when the modality delivered is infrared.
Is 97024 billed in 15-minute units?
No. It is an untimed modality, so report one unit for the service rather than counting 15-minute increments.
Can a professional component modifier be appended?
No. The CMS therapy-service rule specifies that the professional component modifier does not apply.
What documentation supports 97024?
Document the body area treated, that diathermy was delivered, and its clinical purpose, such as addressing musculoskeletal pain or stiffness.
How does the therapy multiple procedure payment reduction affect 97024?

Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
