One of the latest changes in the field of oncology billing for 2026 concerns the billing of radiation therapy procedures. A number of codes frequently used, such as 77385, 77386, and 77014 have been deleted. Instead of coding claims for radiation therapy based on the method used, claims will be coded depending on the level of the complexity of the treatment performed. In other words, proper documentation is needed to prove the complexity of the case. Failing to follow this change might result in low payment or denial of the claim. We have already made adjustments to the charge capture forms and billing process to guarantee the correct coding of radiation oncology claims.

Our billing services integrate seamlessly with your EMR or EHR systems to facilitate appropriate data transfer and claim processing.
