Hematology Billing

Hematology Billing That
Survives an OIG Audit.

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

Where Hematology Billing Revenue Gets Lost

These are the six billing failure points we see most often in hematology practices — and the ones our team resolves systematically from day one.

⏱️

Infusion Time Documentation Gaps

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.

💊

Drug Unit Mismatches

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.

🩸

ESA Hemoglobin Threshold Violations

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.

📋

Missing Modifier 25

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.

🔄

Sequencing Errors on Same-Day Infusions

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.

📆

High-Cost Drug Auth Lapses

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

High-Value CPT & HCPCS Codes We Optimize for Your Practice

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 CodeDescriptionCommon Issue
96413/96415Chemo infusion, initial / additional hourRequires direct physician supervision; time must match documented start/stop
96365/96366Non-chemo therapeutic infusionUsed for iron, IVIG, rituximab in non-cancer context
J0885Epoetin alfa (Epogen, Procrit)Requires hemoglobin below 10 g/dL documented before initiation
J9312RituximabDose-to-units calculation errors are a top denial driver
J2796Romiplostim (Nplate)Requires ITP diagnosis, platelet count below 30,000/μL, prior treatment failure
Modifier 25Same-day E/M with infusionNeeds independent MDM documented beyond the infusion order

Common Questions About Hematology Billing

Straight answers to what practices usually ask before they switch.

Non-chemotherapy infusions use CPT 96365 for the initial hour and 96366 for each additional hour. Chemotherapy infusion starts with 96413 for the initial hour and 96415 for each subsequent hour. The distinction matters significantly — chemotherapy codes reimburse at higher rates and require different documentation.
Erythropoiesis-stimulating agents (ESAs) like epoetin alfa (J0885) and darbepoetin alfa (J0881) are billed as HCPCS drug codes per unit administered. For Medicare patients, ESAs require hemoglobin documentation below 10 g/dL prior to initiation and must be stopped if hemoglobin exceeds 12 g/dL. Missing this threshold documentation is the primary cause of ESA claim denials.
Yes, with modifier 25. A significant, separately identifiable E/M service on the same day as a therapeutic infusion is billable. The E/M documentation must stand on its own — the infusion note alone doesn't support a separate E/M. The E/M must reflect medical decision-making beyond the infusion order.
The top three drivers account for nearly 70% of denied dollars: infusion time documentation that doesn't match the billed code (30% of denials), drug units billed that don't match the administration record, especially with weight-based dosing (25% of denials), and modifier 25 missing on a same-day E/M visit (15% of denials).
