Drug units, wastage, and regimen auth errors cost hematology and oncology practices recoverable revenue every day.
Hematology and oncology bill the highest per-claim dollars in medicine, chemotherapy, biologic, and hematology drugs, complex infusion days, and tightly controlled regimens. A single J-code, wastage modifier, or missing authorization can wipe out a five-figure claim. Manual billing teams catch a fraction of the errors. Ember catches all of them.

Where oncology revenue leaks
The denial patterns Ember was built for
Oncology runs the highest per-claim dollars in medicine, chemotherapy and biologic drugs, complex infusion days, and tightly controlled regimens. A single J-code, wastage modifier, or missing authorization can wipe out a five-figure claim. Ember closes each gap.
01 · Drug units & wastage
High-cost J-codes denied on units and missing wastage modifiers.
Chemotherapy and biologic agents are billed by exact units against documented dose, with discarded drug reported under JW and single-dose vials attested under JZ. A unit error or a missing wastage modifier on a five-figure drug becomes a denial or a takeback. Ember keeps J-codes, units, and wastage accurate on every infusion before submission.
J9299 · J9035 · J2505 · JW · JZ02 · Infusion administration
A full chemo day collapsing into a partial payment.
Infusion administration follows a strict hierarchy, one initial code, then sequential, concurrent, and additional-hour codes against documented start and stop times. Get the sequencing wrong and a complex multi-drug day is billed as a fraction of the work performed. Ember applies the hierarchy against the documented times so the whole day is captured.
96413 · 96415 · 96417 · 9636703 · Regimen auth & pathways
Drugs and chair time given before coverage is confirmed.
High-cost regimens require prior authorization, step-therapy clearance, and NCCN-pathway alignment that shift constantly by payer. Treat before coverage is locked and the practice eats the drug cost. Ember confirms regimen authorization and pathway requirements and gathers documentation before the patient is in the chair.

One source of truth.
Ember connects clinical documentation, payer policy, and contract terms into a single intelligence layer. Built for the J-codes, infusion hierarchy, and regimen authorizations oncology billing requires.

Audit upstream.
Appeal downstream.
Two workflows do most of the work for oncology practices. The first prevents denials before they happen. The second recovers the ones that slip through.
Pre-bill audit
Catch the missing wastage modifier before the claim leaves.
Ember reviews every chemo day against coding standards, payer policy, and your contracts. Unit errors, missing JW/JZ, and under-billed infusion hours are flagged before submission, on the highest-dollar claims you bill.
- 1
Ingest the encounter
Pulls infusion records, documented start/stop times, drug administration logs, and regimen authorization status from your EHR.
- 2
Validate against rules
Checks J-code units, JW/JZ wastage, the infusion administration hierarchy, and regimen auth/pathway status against each payer's specific policies.
- 3
Recommend with citation
Returns the suggested correction tied to the exact CMS rule, payer policy, NCCN pathway, or contract term.
- 4
Educate the provider
Coding and documentation patterns drive provider-level coaching, so infusion timing and wastage capture improve across the practice.

Pull. Review. Push.
When a denial occurs, Ember identifies the root cause, retrieves infusion records and regimen documentation, references payer medical-necessity policy, NCCN pathways, and contract terms, drafts the appeal, and tracks it through adjudication.

The full revenue cycle
From eligibility to adjudication. Covered.
Audit and appeals are the workhorses, but Ember protects oncology revenue at every stage of the cycle.
Eligibility Verification
Confirms active coverage and drug-benefit structure before treatment, and flags coverage gaps on high-cost regimens before they become takebacks.
Prior Auth & Step Therapy
Confirms regimen authorization, step-therapy and pathway requirements, gathers the documentation payers require, and submits before the patient is in the chair.
AI Medical Coding
Reviews 100% of chemo days, J-code units, JW/JZ wastage, and the infusion administration hierarchy, against national standards and payer rules before claims submit.
Pre-bill Audit
Predicts and prevents denials before claims go out, catching unit errors, missing wastage modifiers, and under-billed infusion hours before they generate write-offs.
Denial Management
Full appeal lifecycle for every oncology denial type, medical necessity, units, bundling, step therapy, and auth failure, tracked to adjudication.
Underpayment Recovery
Parses contracts to model what each drug and infusion should pay under ASP-based terms, then surfaces line-item underpayments at scale.
