No prior authorization for the drug
IV iron, biologics and growth factors are frequently on payer prior authorization lists.
How we prevent it: We verify drug authorization requirements when treatment is ordered and track approved units and dates.

OVERVIEW
Hematology billing done right
Hematology billing centers on infusion and injection services and high-cost drugs. Iron infusions, biologics, transfusions and growth factors all need exact start and stop times, the correct infusion hierarchy, accurate drug units and NDC numbers to be paid in full.
Diagnoses must also be specific. Payers check anemia type, coagulation disorders and malignancy codes against their drug policies, and a vague diagnosis is one of the fastest ways to lose payment on an expensive infusion.
We code hematology infusion visits from the nursing and administration record, bill drugs with the right HCPCS units and waste modifiers, and manage prior authorizations for specialty drugs before the patient is in the chair.
Also see our medical coding, denial management, eligibility verification and revenue cycle management services.
CODING
Common hematology CPT & HCPCS codes we bill
Hematology claims combine administration codes with drug codes. Both have to line up with the infusion record.
| Code | Description | What we watch for |
|---|---|---|
| 96365 | IV infusion for therapy or diagnosis, initial, up to 1 hour | Only one initial service per encounter unless a separate IV site is required. |
| 96366 | IV infusion, each additional hour | Requires more than 30 minutes beyond the first hour, supported by documented times. |
| 96367 | IV infusion, additional sequential infusion of a new drug, up to 1 hour | For a different drug given after the initial infusion through the same line. |
| 96374 | IV push, single or initial drug | A push is 15 minutes or less, or an injection the provider personally administers. |
| 96372 | Therapeutic, prophylactic or diagnostic injection, subcutaneous or intramuscular | Used for growth factors and B12; not billed with an E/M without modifier 25 where required. |
| 36430 | Transfusion, blood or blood components | Report once per encounter regardless of the number of units transfused. |
| 38222 | Bone marrow biopsy and aspiration, same site | Use 38220 or 38221 when only an aspiration or only a biopsy is performed. |
| 99195 | Phlebotomy, therapeutic | For conditions such as hemochromatosis and polycythemia, not routine blood draws. |
| J1439 | Injection, ferric carboxymaltose, 1 mg | Units must match the dose given; payers often require documented iron deficiency and failed oral iron. |
| J2506 | Injection, pegfilgrastim, excludes biosimilar, 0.5 mg | Biosimilars have their own Q-codes; billing the wrong code is a common denial. |
Code descriptions are summarized. CPT® is a registered trademark of the American Medical Association. Coverage and payment rules vary by payer and change every year; we code to the current code set and your payers’ policies.
Modifiers that matter in hematology billing
JW
Drug amount discardedReports wasted drug from a single-dose vial on its own claim line.
JZ
Zero drug wastedRequired by Medicare on single-dose drug claims when nothing was discarded.
25
Significant, separate E/MFor a visit that goes beyond the pre-infusion assessment on an infusion day.
59 / XU
Distinct procedural serviceWhen a second initial service is justified by a separate IV access site.
DENIALS
Why hematology claims get denied
The denial reasons we see most often in hematology billing, with the claim adjustment reason code (CARC) payers usually attach, and what we do so they don't happen again.
Diagnosis does not support the drug
Payers deny infusions when the ICD-10 code is not on the drug’s covered diagnosis list.
How we prevent it: We check diagnosis codes against each payer’s drug policy and query the provider when specificity is missing.
Missing NDC or drug information
Medicaid and many commercial plans require the NDC, unit qualifier and quantity on drug lines.
How we prevent it: Our charge entry includes NDCs and our scrubber stops claims without them.
Administration codes bundled
Hydration billed with a therapeutic infusion, or two initial services in one visit, are bundled.
How we prevent it: We apply the CPT infusion hierarchy and only report hydration when it is medically necessary and separate.
Missing JW or JZ modifier
Medicare rejects single-dose drug claims that do not report waste or no waste.
How we prevent it: Every single-dose drug line is checked for the correct waste modifier before submission.
HOW WE WORK
How we run your hematology revenue cycle
From the first eligibility check to the final patient payment, one dedicated team handles every step and reports back to you.
01
Eligibility and authorization
We verify coverage, benefits, copays and deductibles before the visit. For hematology, we check prior authorization for IV iron, biologics and growth factors.
02
Charge capture and coding
Our coders review documentation and assign CPT, HCPCS and ICD-10-CM codes to the highest supported specificity. Infusion times, routes and drug units are coded from the administration record.
03
Claim scrubbing and submission
Every claim is checked against NCCI edits, payer policies and modifier rules before it goes out electronically, so it is paid on the first pass.
04
Payment posting and reconciliation
We post ERAs and EOBs, compare payments to your contracted rates and flag underpayments for appeal.
05
Denial management and A/R follow-up
Every denial is worked: corrected, appealed or escalated, with root causes fed back to the front end. Drug denials are appealed with the clinical criteria from the payer’s policy.
06
Reporting and patient billing
You get clear monthly reports on collections, denials and A/R aging, and patients get easy-to-read statements and answers to billing questions.
COMPLIANCE
Hematology payer rules we track for you
Rules that change how hematology claims must be coded, documented and submitted.
Infusion hierarchy: chemotherapy and complex drug administration rank above therapeutic infusions, which rank above hydration, and only one initial service is reported per encounter.
Time documentation: start and stop times decide whether infusion hours and pushes are billable.
Drug units and waste: HCPCS units must match the dose, with JW or JZ reported on single-dose vials.
ICD-10 specificity: anemia type, cause and linked chronic conditions drive coverage for infused drugs.
FAQ
Hematology billing questions
Do you bill both the drug and the administration?
Yes. We bill the administration CPT codes and the drug HCPCS codes with correct units, NDCs and waste modifiers so both lines are paid.
Can you manage prior authorizations for infusions?
Yes. We submit and track authorizations for IV iron, biologics and other specialty drugs, including renewals before an approval expires.
Do you work with hematology-oncology practices?
Yes. We bill benign hematology and hematology-oncology, including chemotherapy administration. See our oncology billing page for chemotherapy details.
How much do your hematology billing services cost?
We charge a percentage of what we actually collect for you, with no upfront or setup fees. Your rate depends on claim volume and the services you need, so we quote it after a free review of your current billing.
Do we have to change our EHR or practice management system?
No. We work inside the systems you already use, and your data stays yours. We set up secure access, learn your workflows and start working claims without disrupting your front desk.
