Securing Revenue Integrity for High-Complexity Cancer Care

Oncology billing carries some of the highest financial stakes in medicine — chemotherapy administration codes (96401–96549), biosimilar substitution rules, and prior authorization for high-cost specialty drugs each require precise, payer-specific handling. A single denied prior auth on a six-figure treatment plan can devastate a practice's cash flow. We track these details so oncology practices don't absorb that risk.

Payer Enrollment & Compliance

Keeping Oncology Practices Enrolled and Compliant

We manage license renewal tracking, monthly OIG/SAM exclusion checks, and enrollment across the payers and specialty pharmacy networks most active in oncology. Because high-cost drug authorizations often require re-verification mid-treatment, we monitor authorization status throughout a patient's full treatment course, not just at intake.

Common Questions

Oncology Billing Credentialing — FAQ

How do you handle prior authorization for high-cost oncology drugs?
We verify authorization before treatment begins and monitor status throughout the full treatment course, since many high-cost drug authorizations require re-verification mid-treatment — a common point where practices lose revenue if not tracked proactively.
Do biosimilar substitution rules affect my billing?
Yes — payers have different rules on originator versus biosimilar billing, and using the wrong one can trigger denials. We track payer-specific biosimilar policies to ensure correct billing.
Why do my chemotherapy administration claims get denied?
The most common cause is incorrect sequencing when multiple drugs are administered in the same session under codes 96401–96549. We review session-level coding before submission to catch this.
How specific does my ICD-10 staging documentation need to be?
Payers increasingly require detailed staging specificity to approve oncology claims. We review documentation against each payer's specificity requirements before submission to prevent denials.
