Oncology has the highest claim denial rates of any specialty in American medicine. Complex drug regimens, frequent prior authorization requirements, high-cost infusions, and constantly evolving payer policies combine to produce denial rates that routinely exceed 12% of billed charges. For a mid-sized oncology practice, that can represent $3–5 million in at-risk revenue per year. Modern AI-driven denial management agents working alongside oncology billers can raise overturn rates from the high 40s to over 80% by classifying denials by root cause, pulling relevant clinical documentation from Epic, drafting payer-specific appeal letters referencing NCCN compendia, and routing the assembled package to a human reviewer for final sign-off. Honey Health's agents pull documentation via Epic's FHIR APIs, read billing transaction data through Clarity extracts, and log appeal history back into the patient chart so it's visible to future billers and clinicians. For an oncology practice billing $40M in annual charges with a 12% denial rate, improving overturn rate from 47% to 81% represents roughly $1.6M in incremental recovered revenue per year.
