Oncology credentialing involves unique considerations around chemotherapy administration, drug reimbursement, and specialized treatment protocols. Medical oncologists certified by ABIM must credential for both evaluation/management services and drug administration. The buy-and-bill model for oncology drugs requires that practices demonstrate financial capability and proper drug handling protocols during credentialing. Payers may require additional documentation for participation in oncology-specific value-based care programs or bundled payment arrangements.

Frequently Asked Questions
Does chemotherapy administration require special credentialing?
Yes. Oncology practices administering chemotherapy need to credential for drug administration services, demonstrate proper handling protocols, and may need specific facility certifications.
