Hematology practices lose $60,000 to $180,000 a year to infusion sequencing errors, drug unit mismatches, and ESA documentation gaps — with denial rates running 18% to 28%, well above most outpatient specialties.
Common Billing Challenges
These are the six billing failure points we see most often in hematology practices — and the ones our team resolves systematically from day one.
30% of denials trace back to infusion time that doesn't match the billed code — a 43-minute chemo infusion charted as 9:05 to 9:48 doesn't support a full-hour 96413.
25% of denials come from weight-based dosing errors, like rounding 6.75 units of J9312 up to 7 instead of down to the administered dose.
Billing an ESA without a documented hemoglobin below 10 g/dL before initiation — or continuing after it exceeds 12 g/dL — is one of the most frequently cited patterns in hematology OIG enforcement.
15% of denials happen when a same-day E/M visit is billed without modifier 25, or the E/M note doesn't reflect independent medical decision-making beyond the infusion order.
Chemo infusion must be primary over therapeutic drug infusion and hydration — get the hierarchy wrong and the claim pays at the wrong rate, which looks like payment but isn't.
Patients on romiplostim or similar agents for 18+ months need auth renewals tracked 30 days ahead — a lapse means claims going out with no coverage behind them.
Key Procedure & Drug Codes
Our coders hold specialty-specific credentials and train continuously on the codes that drive the most revenue — and the most denials — in hematology.
| CPT/HCPCS Code | Description | Common Issue |
|---|---|---|
| 96413/96415 | Chemo infusion, initial / additional hour | Requires direct physician supervision; time must match documented start/stop |
| 96365/96366 | Non-chemo therapeutic infusion | Used for iron, IVIG, rituximab in non-cancer context |
| J0885 | Epoetin alfa (Epogen, Procrit) | Requires hemoglobin below 10 g/dL documented before initiation |
| J9312 | Rituximab | Dose-to-units calculation errors are a top denial driver |
| J2796 | Romiplostim (Nplate) | Requires ITP diagnosis, platelet count below 30,000/μL, prior treatment failure |
| Modifier 25 | Same-day E/M with infusion | Needs independent MDM documented beyond the infusion order |
