Oncology medical billing services

Oncology is the highest-stakes billing in outpatient medicine: expensive drugs, complex infusion coding, prior authorizations on nearly everything and payers that audit closely. A missed authorization or a unit error can cost more than a month of visits.

What makes oncology billing different

General billers treat every specialty the same. These are the rules, code families and payer habits that decide whether oncology claims pay the first time.

  • Chemotherapy administration (96401–96549) follows a hierarchy of initial, sequential and concurrent codes with time thresholds.
  • Every drug needs the right J-code, units converted from the dose, and wastage documented with JW or JZ.
  • Prior authorization is required for most regimens and for supportive drugs; changes in regimen require new authorization.
  • Radiation oncology, if provided, has its own code set with treatment planning, simulation and delivery codes.

Denials we see most in oncology

Every denial gets a root cause, a fix and a feedback loop, so the same denial stops coming back.

Authorization mismatches

Drugs denied because the regimen changed after authorization. We track authorizations against the active regimen and update before infusion.

Unit and wastage errors

Drug lines denied or underpaid. Units converted per code; wastage modifiers applied.

Administration hierarchy

Infusion codes denied for incorrect initial and sequential logic. Applied from the infusion record.

Oncology billing questions

Why is oncology billing so unforgiving?

Because the dollar amounts are large and the rules are specific: authorizations per regimen, units per J-code, wastage per payer. One error on a drug line can cost thousands, so every line is verified.

Do you track authorizations when regimens change?

Yes. A new drug or a dose change often needs a new authorization, and we update before the next infusion rather than after the denial.

Can you tell us which drugs are profitable to infuse in-office?

Yes. We report reimbursement against acquisition cost by drug so you can make buy-and-bill decisions on data.
