Frequently Asked Questions

What is oncology medical billing in California?
Oncology medical billing is the process of coding and submitting claims for chemotherapy, immunotherapy, radiation, and infusion services in compliance with Medicare, Medi-Cal, and commercial payer rules. It includes drug J-code billing, prior authorizations, and documentation that supports medical necessity.
Oncology billing involves high-cost drugs, time-based infusion coding, and strict payer guidelines. Even small coding or documentation mistakes can lead to denials, underpayments, or audits — especially with Medicare and Medi-Cal in California. Drug wastage, NDC requirements, and JW modifier rules add layers of complexity that demand specialist coders.
Yes. Most commercial insurers and Medi-Cal plans require prior authorization for chemotherapy, biologics, and specialty infusions. If approval is not obtained before treatment, the claim may be denied or left unpaid. Our automated PA workflows ensure authorizations are confirmed before every treatment begins.
