Chemotherapy & Infusion Coding Errors That Delay Oncology Reimbursements

How Everest A/R Management Group Helps Oncology Practices Recover High-Dollar Claims Faster

Chemotherapy and infusion services drive a large share of oncology revenue—but they also carry the highest denial and delay risk in medical billing.

At Everest A/R Management Group, we consistently see oncology practices losing 15–35% of expected revenue due to avoidable chemotherapy and infusion coding errors.

Below are the most common issues—and how Everest fixes them.

The Most Costly Chemotherapy & Infusion Coding Errors

Incorrect CPT Sequencing

Many claims fail due to improper sequencing of:

• Chemotherapy administration

• Therapeutic/diagnostic infusions

• Hydration services

Everest Solution:
Our oncology-certified coders ensure payer-compliant sequencing before claims are submitted—preventing automatic denials.

Infusion Time Documentation Errors

Missing or inconsistent start/stop times lead to:

• Down coded claims

• Requests for records

• Payment delays

Everest Solution:
We audit infusion documentation against CPT time thresholds to ensure every billable minute is reimbursed.

Multiple “Initial” Infusion Codes

Payers allow only one initial code per encounter, yet this remains a frequent rejection trigger.

Everest Solution:
Encounter-level claim validation eliminates coding conflicts before submission.

J-Code & Drug Unit Billing Mistakes

High-dollar chemotherapy drug claims fail due to:

• Incorrect units

• Missing JW/JZ modifiers

• NDC mismatches

Everest Solution:
We align pharmacy, nursing, and billing data to ensure accurate J-code, unit, and wastage reporting—reducing audit exposure.

Modifier Misuse

Incorrect or unsupported modifiers lead to:

• Bundled payments

• Partial reimbursements

• Appeals backlog

Everest Solution:
Modifiers are applied only when documentation fully supports them, protecting reimbursement and compliance.

Prior Authorization Gaps

Even perfectly coded claims deny when:

• Drugs exceed authorized limits

• Authorizations expire

• Billed services don’t match approvals

Everest Solution:
Our billing workflows cross-check authorizations against every chemotherapy and infusion claim.
