Customer Situation
A multi-specialty regional cancer center with a high chemotherapy infusion volume faced a major financial challenge. Despite having an in-house billing team, the center was experiencing a denial rate exceeding 20% for infusion-related claims, straining cash flow and increasing appeal backlogs.
Challenges
Our audit identified multiple root causes for the denials:
-
Medical Necessity Denials: Errors in linking CPT infusion codes (e.g., 96413, 96415) with the correct J-codes (e.g., J9045 for Carboplatin, J9201 for Gemcitabine) and supporting ICD-10-CM diagnosis codes.
-
Documentation Gaps: Missing infusion start and end times prevented justification of prolonged infusion billing.
-
Incorrect Modifier Use: Denials occurred when services like hydration infusion (CPT 96360) and chemotherapy infusion (CPT 96413) were billed on the same day without modifier -59, which clarifies distinct services.
-
Reactive Workflow: The in-house team focused on appeals after denials rather than proactive prevention. No claim scrubbing system was in place to catch issues before submission.
Solution
The cancer center partnered with a specialized oncology billing company to redesign its revenue cycle management. The solution was built on accuracy, prevention, and training:
Expert Code Review & Training
-
Conducted a detailed audit of top-denied claims.
-
Delivered targeted training for clinical and billing staff on coding accuracy, modifier use, and documentation essentials.
Systematic Modifier Application
-
Introduced consistent, rule-based application of modifiers (e.g., -59 for distinct services, JW for discarded drug amounts).
-
Significantly reduced denials caused by bundled services.
Pre-Bill Audits (“Claim Scrubbing”)
-
Implemented automated pre-bill audits using proprietary software to flag errors before claim submission.
-
Common triggers: missing modifiers, incomplete documentation, unlinked diagnoses.
-
Prevented recurring errors and reduced reliance on appeals.
Results
-
Denial rate reduced by 75%+ (from over 20% to under 5%)
-
Improved cash flow, with most claims paid on first submission
-
Recovered significant denied revenue through proactive appeals
