Clinical & Coding Specifications
Clinical Context
A typical patient scenario involves an individual diagnosed with a superficial skin cancer, such as basal cell carcinoma or squamous cell carcinoma, located on sensitive areas like the lip, eyelid, or external ear. The patient is referred to a radiation oncology physician for treatment. The clinical workflow includes evaluation, planning, and delivery of superficial or orthovoltage radiation therapy, typically performed in an outpatient hospital setting. The procedure is delivered per day, and may be part of a multi-day treatment regimen. The provider may use simulation procedures to plan the radiation field prior to delivery.
