Coding accuracy is vital for oncology practices providing radiation therapy. CPT code 77280, representing simple simulation, is a foundational step in treatment planning. Proper use of this code ensures correct reimbursement for the initial setup and precise field definition before radiation delivery.
This ultimate guide offers a comprehensive overview of CPT code 77280. We will cover its description, common clinical scenarios, and applicable modifiers. We will also share the essential billing and reimbursement guidelines related to this CPT code.
Thus, read this guide till the end if you want to streamline your radiation therapy billing workflow for a healthier revenue cycle.
CPT Code 77280 – Description
CPT code 77280 is from the ‘Clinical Treatment Planning (External and Internal Sources) for Radiation Treatment’ code range. The American Medical Association (AMA) manages this code range like all other CPT code ranges.
It covers a simple level of service, which involves using a simulator or other imaging modality to determine the location and size of ports for radiation therapy.
Scenarios Where CPT Code 77280 is Applicable
The following are some real-world clinical scenarios where this CPT code applies:
Single Superficial Skin Lesion
Picture a 65-year-old patient with a small, well-defined squamous cell carcinoma on the cheek. The radiation oncologist recommends that a single, direct radiation field cover the lesion and shield the surrounding normal tissue, such as the eye.
Thus, the healthcare provider uses a radiation therapy simulator to visualize the treatment area and define the field borders with lead cutouts. He also documents the patient’s position for reproducible treatment delivery. It requires a simple setup with basic skin marking and no complex blocking or multiple angles.
Here, CPT code 77280 applies.
Keloid Scar Treatment
Imagine a 45-year-old patient with a persistent keloid scar on the chest following surgery. The radiation oncologist decides to treat it with superficial electron beam therapy using a single, direct field.
Therefore, the healthcare provider uses the radiation therapy simulator to determine the appropriate applicator size and placement to cover the keloid. Besides, simple skin markings define the treatment area.
Here, CPT code 77280 applies.
Bone Metastasis in a Single Vertebra
Consider a 55-year-old patient with metastatic breast cancer. She has a solitary, small area of bone metastasis in one of the lumbar vertebrae, causing localized pain. The radiation oncologist advises treating it with a single posterior radiation field.
Therefore, the provider uses fluoroscopy (an imaging modality) to visualize the vertebra. He also defines the treatment field to cover the metastasis with a small margin and mark the patient’s skin for daily setup.
Since the simulation is straightforward and involves a single field and a standard patient positioning, CPT code 77280 applies.
Applicable Modifiers for CPT Code 77280
Modifier 59 applies to CPT code 77280 when the radiation oncologist performs a simple simulation of a single treatment area on the same service date as another service that is distinct and separately identifiable.
However, the documentation must support this modifier’s usage. Besides, you should utilize the modifier subsets X{EPSU} if they describe more specifically why the service covered under CPT code 77280 is eligible for a separate reimbursement.
Here’s a quick overview of what the X{EPSU} modifiers entail:
- XE – Separate Encounter
- XP – Different Physician
- XS – Separate Structure
- XU – Unusual, Non-overlapping Service
CPT Code 77280 – Billing & Reimbursement Guidelines
Discussed below are the key billing and reimbursement guidelines related to CPT code 77280:
Fulfill the Documentation Requirements
Insurance payers, whether Medicare, Medicaid, or private, emphasize complete and accurate documentation. Therefore, you should focus on providing adequate documentation to support the medical necessity of the procedure covered by CPT code 77280. It should include the following:
- Date of service.
- Medical indication for performing the simulation.
- Details related to the patient’s position and immobilization devices used (if any).
- Description of the treatment field, including the location, size, and blocking (if any).
- Images of the simulated fields, such as digital images or films.
- Physician review and approval of the simulation.
Beware of the Service Bundling Rules
CPT code 77280 includes payment for the CPT guidance for radiation therapy planning. Therefore, when billing for the simulation covered under CPT 77280, do not report CPT 77014 separately.
Moreover, if you developed an IMRT plan, the simulation services described under CPT 77280 are bundled into the CPT code 77301. Thus, you should not report CPT 77280 with CPT 77301.
Bill Only Once On Any Given Day
Typically, radiation therapy requires one to three simulations. However, you should not report CPT code 77280 more than once on any given day. If you want to bill more than three simulations, your documentation must demonstrate the medical necessity of all simulations.
Review Payer-Specific Policies
Reimbursement guidelines significantly vary from payer to payer. Thus, you must communicate with the specific payer and understand their billing requirements before submitting a claim with CPT code 77280. Moreover, the allowed billable simulations per patient may also vary across payers.
Summary
Hopefully, all the details discussed in this comprehensive guide related to CPT code 77280 will help you streamline your radiation therapy billing. Below is a quick overview of the key takeaways:
First, we explained the descriptor of CPT 77280. It covers setting up the radiation therapy field, including initial setup and planning to define the specific area on a patient’s body that will receive radiation treatment.
Next, we shared some clinical scenarios where this simple radiation therapy simulation applies. These include bone metastasis in a single vertebra, keloid scar treatment, and a single superficial skin lesion.
We also discussed that you should append modifier 59 when you bill the simulation service with procedures that are typically performed together. It helps bypass the bundling edits and ensure fair reimbursement.
Finally, we looked into the billing and reimbursement guidelines related to this CPT code.
