Oncology billing across treatment cycles
Oncology billing spans months of treatment, often across plan years. Our oncology billing services re-verify coverage before each cycle, track deductibles and out-of-pocket maximums as they reset, and identify secondary coverage. Patients who lose employer coverage mid-treatment are flagged early so the new plan's authorization is requested before the next cycle, using our eligibility checks.
Authorization for chemotherapy regimens
Payers approve regimens by drug, dose and schedule, often comparing them with clinical guidelines or pathways. A change in any of these may require a new approval, and supportive drugs such as antiemetics or growth factors may need their own. Our authorization team tracks each request and its expiration against the treatment calendar, so an approval does not lapse between cycles.
Coding chemotherapy administration
| Code | Descriptor (summary) |
|---|---|
| 96413 | Chemotherapy administration, IV infusion; up to 1 hour, single or initial drug |
| 96415 | Each additional hour |
| 96417 | Each additional sequential infusion of a different drug, up to 1 hour |
When several services happen in one visit, chemotherapy administration ranks above therapeutic infusions, which rank above hydration, when choosing the initial service. Drugs are billed with HCPCS codes and units based on the dose descriptor, Medicaid claims carry the NDC, and Medicare requires JW or JZ for single-dose containers. Coding review checks infusion start and stop times against the codes billed.
Oncology claims and denials
Drug claims are often denied when the diagnosis falls outside covered indications, when the payer's preferred biosimilar was not used, or when the dose exceeds the approved amount. Appeals cite the approval, compendia support and the treatment record. For Medicare patients in qualifying clinical trials, routine costs are billed with the Q1 modifier, investigational items with Q0, and diagnosis code Z00.6.
Oncology AR follow-up
High-cost drug claims are followed up promptly and compared with contract rates through underpayment recovery, so short payments are addressed before appeal windows close. Aged balances are worked by payer and cycle through AR management, and a free billing assessment is a simple way to see where drug revenue is slipping.
Oncology medical billing services
Oncology medical billing centers on high-cost drug claims, infusion coding and prior authorization discipline. We verify benefits before treatment plans are finalized, secure authorizations for chemotherapy and immunotherapy, and reconcile drug claims against administered doses so J-code billing matches the medical record. Denials on oncology claims are worked with clinical documentation attached — payers expect it, and the appeal wins when it is there.
