Radiation oncology is the specialty of medicine that utilizes high-energy ionizing radiation in the treatment of malignant neoplasms and certain non-malignant conditions. It uses several distinct therapeutic modalities; teletherapy, brachytherapy, hyperthermia, and stereotactic radiation. These may be directed at either malignant or benign lesions. Indications and Limitations of Coverage Radiation oncology services are considered medically reasonable and necessary when the following conditions outlined in this policy are indicated and documented in the patient’s medical records. Payment is limited to services furnished in office, inpatient hospital, and outpatient hospital. A freestanding radiation oncology center is considered, for billing purposes, an office. Tumor Mapping and Clinical Treatment Planning (Codes 77261-77263) Treatment planning (codes 77261–77263) is a one-time service per course of therapy. Multiple treatment plans for a single course of treatment are not medically necessary. This is a professional service only and the physician is responsible for all of the technical aspects of the treatment planning process. Therapeutic Radiology Simulation - Aided Field Setting (Codes 77280-77295) Simple radiation therapy field setting applies to:
Intermediate radiation therapy field setting applies to:
Complex radiation therapy field setting applies to:
Three dimensional radiation therapy field setting involves three-dimensional computer-generated reconstruction of tumor volume and surrounding critical normal tissue structures from direct CT scan and/or MRI data in preparation for non-coplanar or coplanar therapy. The simulation uses documented 3-D beam’s eye view volume-dose displays of multiple or moving beams. Documentation with 3-D volume reconstruction and dose distribution is required. Three-dimensional simulation and treatment is clinically warranted when one or more of the following conditions exist:
Radiation oncology simulation is defined as the process of determining and establishing the radiation therapy treatment portals to a specific treatment volume. Simulation is accomplished through the use of equipment such as dedicated simulator, linear accelerator, cobalt unit, ortho voltage X-ray machine, diagnostic X-ray fluoroscopy unit, or other equipment used to establish areas to be treated without delivering radiation treatment. Ordering and interpreting special tests may be required to assist in the field settings. Following treatment planning, simulation is used to actually direct the treatment beams to the specific volumes of interest. Simulation may be carried out on a dedicated conventional simulator or CT scanner, radiation therapy treatment unit (e.g., linear accelerator), or using diagnostic imaging equipment (e.g., fluoroscopy, CT, MR). The complexity of simulation is based on the number of ports, volumes of interest, and the inclusion and type of treatment devices. However the number of films taken per treatment, the modality from which images for simulation are obtained, and the use of fluoroscopy are not determinants of complexity. Portal changes based on unsatisfactory initial simulation(s) are not reported as additional simulations. Additional simulations may be necessary during treatment in order to account for changes in port size, boost dose, or tumor volume. However, minor changes in port size without changes in beam or without clinical justification do not warrant an additional charge or a higher level of complexity. The inclusion of treatment devices in the simulation process typically increases the complexity. Simulation without the inclusion of devices or with any pre-made devices (e.g., blocks, immobilization) is considered simple. Custom devices elevate complexity when clinically appropriate. Documentation of simulation requires a written record of the procedure and hard copy of electronic images and evidence of image review by physicians including signature or initials and data review. Basic Radiation Dosimetry Calculation (Code 77300)
Basic dosimetry calculations may be reported as many times as the calculations are performed. The typical course of radiation therapy will require from one to six dosimetry calculations, depending on the complexity of the patient’s problem. Intensity Modulated Radiotherapy Treatment Planning (IMRT)(Codes 77301 and 77338)
IMRT optimizes inverse treatment planning as opposed to forward treatment planning. The radiation oncologist and physics department decide the tumorcidal dose, acceptable dose to surround structures, the treatment target, then the computer plan is worked backwards to design ports, and beam profiles that yield desired results. While IMRT may be utilized as a single modality or a component of the total, it is not a replacement for conventional or 3-D conformal radiation delivery in all situations. An IMRT plan includes dose-volume histograms for target and critical structure partial tolerance specifications. Dose plan is optimized using inverse or forward planning technique for modulated beam delivery (e.g., binary, dynamic MLC) to create highly conformal dose distribution. Computer plan distribution must be verified for positional accuracy based on dosimetric verification of the intensity map with verification of treatment set-up and interpretation of verification methodology. External Beam Isodose Plan (Codes 77305-77315) The typical course of radiation therapy will require from one to three isodose plans. Usually only one plan per volume of interest will be sufficient, even though some patients may require multiple teletherapy plans during the course of therapy. Situations that may require an extra teletherapy plan include the need to change the machine or the volume of interest. Toward the end of treatment, due to clinical variations of the patient, another plan may be required. Special Teletherapy Port Plan (Code 77321) A teletherapy isodose plan may be medically necessary with a special teletherapy port plan. Brachytherapy Isodose Calculation (Codes 77326-77328) Appliances such as gynecological applicators, afterloading tubes, template needles, etc., are first surgically inserted by the radiation oncologists in, on or around the tumor. Brachytherapy implants may be temporary or permanent, depending upon the type of tumor and the isotope used. Following insertion of the applicators, images are obtained for isodose calculation of the actual implant sources or using non-radioactive material in the applicator. Isodose calculations are then made which determines the amount of radiation that will be absorbed by the tumor per minute or hour. From this calculation, the treatment course can be modified if necessary by increasing or decreasing the patient’s exposure time to the radioisotope. Intravascular brachytherapy may be indicated in the patient with signs or symptoms of in-stent restenosis of the coronary artery, when the restenosis is due to an exaggerated healing response within a previously stented coronary artery/coronary graft vessel. The definition of the levels of complexity of conventional clinical brachytherapy relates directly to the number of sources or ribbons utilized in the procedure. Special Dosimetry (Code 77331) Special radiation dosimetry is not to be routinely performed each time the patient is treated. It would be expected that the utilization of this procedure would correspond with the level of complexity of the clinical treatment planning services provided for the patient. When special dosimetry is employed, the usual frequency will vary from one to six. The monitoring devices utilized for measuring and monitoring can include thermoluminescent dosimeters (TLD), solid state diode probes, special dosimetry probes, or film dosimetry. Treatment/Immobilization Devices (Codes 77332-77334) The typical course of radiation therapy will justify from one to five charges for devices. Complex IMRT treatments may require more than five devices. Multiple treatment devices may be medically necessary during a course of therapy when documentation substantiates multiple volumes of interest/portals, the use of custom-made devices, and/or the necessity of replacement devices. Simple treatment devices include any of the following:
Intermediate treatment devices include any of the following:
Complex treatment devices include any of the following:
Medical Radiation Physics Consultation (Code 77336) Special Medical Radiation Physics Consultation (Code 77370) Stereotactic Radiosurgery Radiation Treatment Delivery (Codes 77371-77373) SRS does not actually remove the tumor; rather, it distorts the DNA of tumor cells causing these cells to lose their ability to reproduce. SRS treatment is often completed in a one-day session (codes 77371 and 77372), although physicians sometimes recommend a fractionated treatment, in which treatments are given over a period of days or weeks. This is referred to as stereotactic radiation therapy (code 77373). There are three forms of SRS, each using different instruments and sources of radiation:
Radiation Treatment Delivery (Codes 77401-77416, 77418, 77421, and 0073T) Portal Verification Film(s)(Code 77417) Radiation Treatment Management (Codes 77427, 77431, 77432, and 77435)
Single session stereotactic radiosurgery is a procedure completed in a single day. It usually involves 2-4 hours of time by the neurosurgeon and may involve 5-6 hours of time by the radiation oncologist and physicist. Multiple session stereotactic radiosurgery involves a prescribed dose of radiation in a series of small doses over multiple sessions to larger and/or multiple sites. Stereotactic radiosurgery is appropriate for the treatment of certain malignant and benign neoplasms of the brain, cranial nerves, meninges, arteriovenous malformations of cerebral vessels, and other non-neoplasmatic conditions. Gamma knife ventalis intermedialis thalamotomy and posteroventral pallidotomy have been shown to be safe and effective treatment options for movement disorders. A small subset of patients with Parkinson’s disease, essential tremor, or other disabling tremor who have been evaluated by a neurologist and determined to be refractory to standard medical therapy will be covered. Stereotactic radiosurgery provides an alternative to conventional surgical stereotactic thalamotomy in patients with concomitant conditions such as a coagulopathy, severe cardiac or respiratory disease or psychological inability to tolerate the conventional awake procedure. Special Treatment Procedures (Code 77470) This service is not intended to be used because a patient has another ongoing medical diagnosis such as diabetes, C.O.P.D., or hypertension. High-dose Rate (HDR) Brachytherapy (Codes 77785–77787) Reasons for Noncoverage Radiation therapy provided for ineligible conditions will be denied as not medically necessary. A provider cannot bill the member for the denied service unless the provider has given advance written notice, informing the member that the service may be deemed not medically necessary and providing an estimate of the cost. The member must agree in writing to assume financial responsibility, in advance of receiving the service. The signed agreement, in the form of a Pre-Service Denial Notice, should be maintained in the provider's records. Services performed for excessive frequency are not medically necessary. Frequency is considered excessive when services are performed more frequently than generally accepted by peers and the reason for additional services is not justified by documentation. Documentation Requirements The patient's medical record must document the medical necessity of services performed for each date of service submitted on a claim, and documentation must be available on request. Documentation must include the planned course of therapy, type and delivery of treatment, level of clinical management involved and ongoing documentation of any changes in course of treatment. A patient referral with diagnostic information and request for consultation for radiation oncology must be maintained in the patient’s record and available upon request. Treatment/Immobilization Devices (Codes 77332-77334) - Additional sets may be allowed only when documentation explains why new or additional devices are necessary. If such documentation is not present, or if the information simply describes the function of the devices, the service will be denied as not medically necessary. While the typical course of radiation therapy may justify the use of 1-5 devices, complex treatments may require more than 5 devices. Examples of acceptable reasons for additional sets of devices are listed below:
Ongoing documentation should include any changes in dosimetry calculations and change in radiation treatment and frequency. The physician’s documentation must be specific to the number of volumes of interest. The specific location of tumor(s) to be treated must be documented as well as the specific number of ports involved with each volume of interest treated. All isodose plans must be checked and signed by the medical radiation physicist and the radiation oncologist. The physician must specify the type of special dosimetry used. The physician’s documentation within the patient’s medical record must support the specific energy levels reported.
