Q: What are the most frequent errors seen in oncology medical billing, and how can practices prevent them?
A: Oncology billing is uniquely complex due to the nature of cancer care, which often involves chemotherapy, radiation therapy, diagnostic imaging, and ongoing patient management. As a result, even minor mistakes in oncology medical billing can lead to significant financial losses, claim denials, or compliance issues.
Here are some of the most common mistakes—and how to avoid them:
-
Incorrect Use of CPT and HCPCS Codes
Oncology treatments require precise coding, especially for chemotherapy administration, biologics, and infusion services. Using outdated or inappropriate codes is one of the top reasons for claim rejections. Regular coding audits and updates are essential. -
Missing or Incomplete Prior Authorizations
Many oncology treatments require prior approval from insurance providers. Failing to secure proper authorization can result in full denial of payment. A robust authorization tracking system is key to preventing this issue. -
Improper Modifier Usage
Modifiers like -59, -25, -76, and others must be applied accurately to denote distinct services, multiple sessions, or repeated procedures. Incorrect modifier use can flag claims for review or denial. -
Lack of Medical Necessity Documentation
Payers often require detailed documentation to justify costly treatments. Missing diagnosis codes or insufficient clinical notes can result in audits or denied claims. -
Unbundling Services Improperly
Separating procedures that should be billed together (or bundling those that shouldn't) leads to non-compliance and underpayment. Understanding NCCI (National Correct Coding Initiative) edits is critical.
