Oncology Billing Plan
Radiation oncology is one of the medical specialties with multiple reimbursement complications. To overcome them, we follow a defined billing process that covers:
- Insurance Verification — coverage and authorization confirmed before treatment
- Treatment Planning Documentation — plans, fractions, and doses recorded completely
- Radiation Delivery Coding — correct CPT codes for every treatment session
- Practice Coding & QA — two-layer checks against upcoding and undercoding
- Billing and Collection — claims filed and balances followed up until paid
Upcoding and undercoding issues are common in oncology billing, but our certified coders fix these while paying keen attention to coding details. The team cross-verifies practice and patient information to ensure no extra codes exist. Further, they enter all charges into the claims correctly — through the same medical coding discipline — to avoid denials, rejections, and penalties.


Frequently Asked Questions
Efficient radiation oncology billing is crucial to providing high-quality cancer care. However, providers have their concerns regarding the billing process. Below we have answered some questions that they frequently ask. Whether you’re practicing radiation oncology individually or affiliated with a hospital, these will effectively clear your confusion. Let’s have a look:
1) What is the billing process for radiation therapy sessions?
Radiation therapy billing starts with documenting the number of fractions and total dose for each treatment course. CPT codes from the 77401-77425 series are then assigned based on the delivery method and complexity — with treatment planning documented separately. Complete fraction counts and dosimetry records are what keep these claims paid.
2) How is cancer-related genetic testing billed?
Genetic and molecular testing is billed with molecular pathology codes (the 81103-81479 series), and most payers require prior authorization with documented medical necessity. Our team verifies coverage before testing and submits with the supporting documentation — preventing the denials that make genetic testing a common write-off area.
3) Is prior authorization required for radiation therapy?
Yes — the majority of payers require prior authorization for radiation treatment before the first session. Authorization must reflect the planned course and fractions; starting treatment without it is one of the most common causes of radiation oncology denials, which is why our verification happens before treatment, not after.
