Pediatric Billing Challenges That Need Precision
Pediatric billing isn’t difficult, it’s detailed. Success depends on aligning every service with payer rules and documentation standards.
-
Prior authorization breakdowns
Expensive oncology drugs administered without pre-approval lead to automatic denials. -
Clinical trial billing errors
Misalignment of research vs. routine care charges creates compliance and audit risks.
-
Incorrect infusion coding
Errors in oncology billing codes for initial vs. sequential vs. concurrent chemotherapy sessions cause underpayments. -
Non-compliance with oncology billing guidelines
Overlooking time-based infusion documentation, drug units, or NCCI edits stalls payments.
-
Drug wastage not reported
Unused vials not billed with modifier JW or JZ result in lost reimbursement opportunities. -
Eligibility verification gaps
Patients not pre-checked for oncology benefits face claim denials and delayed treatment reimbursement.
