Radiation Oncology & Proton Therapy Medical Billing Services
IMRT treatment planning, stereotactic body radiotherapy (SBRT), medical physics consultations, weekly 5-fraction management, and proton therapy prior-authorization defense.
Aethera Healthcare Solutions provides full-service medical billing and revenue cycle management to radiation oncology centers, proton beam therapy facilities, and hospital cancer clinics across the United States. We handle coding, claims, payment posting, denial management, and A/R follow-up end to end — so your team can stay focused on patient care while your revenue cycle runs cleanly.
Typical radiation oncology & proton therapy CPT range we work: 77261–77263, 77300, 77301, 77334, 77338, 77385–77386, 77371–77373, 77427, 77520–77525.
Why radiation oncology & proton therapy billing leaks revenue
IMRT planning (CPT 77301) unbundling denials: NCCI PTP edits denying dosimetry (77300), 3D simulation (77295), or device design (77334) billed during the IMRT development window
Weekly treatment management (CPT 77427) fraction math rejections: Denials triggered when billing fractions out of sequence or misapplying the 3-to-4 fraction carry-over rule at treatment completion
Stereotactic body radiotherapy (SBRT) vs SRS coding disputes: Payers refusing CPT 77373 for non-cranial lesions due to missing fiducial marker tracking or respiratory gating documentation
Proton beam therapy (CPT 77520–77525) prior-auth rejections: Commercial payers denying proton beam as investigational without comparative IMRT/proton DVH dose-volume histogram proof

Radiation Oncology & Proton Therapy billing FAQ
What services are bundled into CPT 77301 (IMRT Planning)?
Under CMS guidelines, CPT 77301 includes the initial 3D simulation (77295), basic dosimetry (77300), and treatment devices (77334) when performed for the initial plan. Physics consultations (77336) and port verification films (77417) remain separately payable during the treatment course.
How do you calculate weekly radiation treatment management (CPT 77427)?
CPT 77427 is reported once for every 5 fractions delivered. At the end of treatment, a remaining cluster of 3 or 4 fractions qualifies for an additional 77427 billing; however, 1 or 2 remaining fractions are non-billable standalone under CMS § 100.1.
