What is this procedure?

Intravenous administration of chemotherapy drugs for cancer treatment. Covers the first hour of infusion in an outpatient or office setting.

Does this require prior authorization?

Yes — Prior authorization is typically required

Step Therapy / Pre-Requirements

Requires pathology-confirmed cancer diagnosis with oncology treatment plan referencing NCCN or equivalent guidelines. Most standard regimens approved readily.

Common Reasons This Gets Denied

Based on insurer policy analysis and claims data patterns. Frequency indicates how often this reason appears.

Chemotherapy infusion request without documentation of baseline organ function testing (CBC, CMP, LFTs, creatinine)

Very Common

Chemo requires baseline and pre-treatment labs to assess tolerability and adjust dosing.

How to prevent this

Ensure current CBC, comprehensive metabolic panel, liver function tests, and renal function within 2 weeks of treatment initiation.

Chemotherapy regimen chosen differs from standard protocols without documented medical justification

Common

Chemotherapy must follow evidence-based regimens (NCCN, COG protocols) for cancer type and stage.

How to prevent this

Document cancer subtype, stage, and standard protocol selection; if off-protocol (investigational or modified), justify with peer-reviewed literature.

Concurrent chemotherapy with radiation therapy without documented indication for combined modality

Occasional

Combined modality typically reserved for specific malignancies and stages per guidelines (e.g., cervical, esophageal, head-neck cancer).

How to prevent this

Document cancer histology and stage supporting combined modality therapy; reference NCCN guidelines or clinical trial evidence.
