Oncology claims are the highest dollar and least forgiving in medicine. A single infusion visit can carry chemotherapy, hydration, and supportive drug administration billed in strict sequence. A radiation course spans weeks of planning, delivery, and weekly management, each with its own code. One unit error or one missed authorization can cost thousands on a single claim. We built our process around both medical and radiation oncology, so the errors that cost the most never happen in the first place.
Oncology billing rewards precision and punishes shortcuts harder than almost any other specialty. Here's where practices lose revenue, and how we close each gap.
Drug units and documented wastage are reconciled against administration records before billing, with the JW modifier applied correctly for single-use vial discard. Unit errors are costly in both directions. Undercoding leaves money on the table. Overcoding invites an audit.
Chemotherapy, therapeutic infusions, hydration, and supportive injections follow a required billing sequence, and each needs documented start and stop times to support the time-based codes behind them. Missequencing is one of the most common sources of preventable denials in oncology.
Authorizations are obtained and tracked per regimen cycle or per radiation course, with renewals requested before the next cycle or fraction is scheduled. When a regimen changes mid-treatment, the authorization gets updated the same day, not after the next claim bounces.
Reimbursement is monitored against acquisition cost under the ASP plus 6% Part B model, so underpayment on high-cost drugs, biologics, and emerging therapies gets caught right away instead of discovered at quarter's end.
Treatment planning, simulation, physics services, delivery, and weekly management each require distinct coding that reflects the physician's actual role and the patient's treatment schedule. The most recent restructuring of radiation delivery codes changed how complexity level and image guidance get billed, and practices still coding against the old framework are leaving money on the table or risking denials.
Many oncology procedures get bundled into a single code, but treatment frequently varies from the exact bundle. That means knowing exactly what's included and what has to be billed separately. Getting this wrong in either direction, adding services that duplicate the bundle or missing services that should be billed apart from it, creates denial risk.
Evaluation and management visits, chemotherapy administration, and supportive drug therapy billed in the correct hierarchy, with J-code accuracy and wastage documentation built into every infusion day.
Treatment planning, simulation, physics services, delivery, and weekly management coded to the current complexity-level framework, with image guidance billed correctly as a technical or professional component depending on the code.
The same infusion and J-code discipline applied to hematologic malignancies and blood disorders, where drug regimens and monitoring visits often follow their own cadence.
Biopsies, tumor excisions, and port placements billed with the modifier accuracy that surgical and oncology rules both require, especially where the two overlap.
High-volume infusion days billed with the same sequencing and wastage discipline whether the center sits inside a hospital system or operates independently.
Coordinated coding across medical, radiation, and surgical oncology teams under one roof, so a patient's care across specialties turns into one clean set of claims instead of three disconnected ones.
Cancer care splits into distinct subspecialties, and each one carries its own diagnostic codes, treatment patterns, and documentation requirements. Here's the range we cover.
Chemotherapy, targeted therapy, immunotherapy, and other systemic treatments coded with the sequencing and J-code accuracy the drug administration hierarchy requires.
Biopsies, tumor excisions, and port placements coded where oncology and surgical billing rules intersect, with documentation and modifier accuracy for every procedure.
Treatment planning, simulation, delivery, and weekly management coded across every technique, including SBRT, IMRT, and brachytherapy, to the current complexity-level framework.
Blood cancers and disorders billed with the same infusion and J-code discipline as solid tumor chemotherapy, adjusted for the monitoring visits and drug regimens hematologic care typically follows.
Surgical and chemotherapy billing for gynecologic cancers, with diagnosis coding and procedure sequencing specific to this patient population.
Billing built around the documentation and authorization patterns pediatric cancer care requires, including age-specific coding considerations and the family-facing sensitivity pediatric billing calls for.
Billing for prostate, bladder, kidney, and testicular cancer care, spanning diagnostic procedures, surgical intervention, and any systemic treatment that follows.
Diagnostic imaging, biopsy, surgical, and systemic treatment billing coordinated across the full breast cancer care pathway, from initial workup through survivorship.
Lung and chest cancer billing, including biopsy, surgical, and radiation coding for a subspecialty where staging and treatment sequencing directly affect which codes apply.
Billing for colorectal, pancreatic, gastric, and other gastrointestinal cancers, coordinated across the surgical, medical, and radiation oncology teams that often share these cases.
Oncology billing punishes a generalist harder than almost any other specialty. A JW modifier applied incorrectly or a radiation code billed under the wrong complexity level can be worth thousands of dollars on its own. Here's what a specialty partner actually does differently.
Most billing companies treat radiation oncology as an afterthought to chemotherapy billing. We treat them as two equally demanding disciplines, each with its own code families, its own documentation rules, and its own denial patterns.
We reconcile drug units and wastage against administration records before every claim, apply the JW modifier where it applies, and monitor reimbursement against acquisition cost so underpayment on high-cost regimens gets caught immediately.
We track the Local Coverage Determinations that apply to your Medicare Administrative Contractor, so if a claim draws a Recovery Audit Contractor review, the documentation behind it is already built to withstand one.
We're a Nevada based billing partner, not a national vendor treating your state as one line item among fifty. Every workflow is HIPAA compliant, with a signed Business Associate Agreement in place before any PHI changes hands.
Your practice gets a dedicated account contact who knows your provider mix, your regimens, and your denial patterns, not a rotating support queue.
Oncology coding spans two distinct disciplines under one specialty. Here's exactly what we work, medical and radiation, and why each family matters.

Sequencing these correctly, active disease versus encounter-for-treatment versus history-of, is one of the most common places oncology claims get denied or misread by a payer. Coding requirements vary by payer, provider type, and documentation. This overview is educational, not billing advice for a specific claim. We verify current payer policy before every submission.
Beyond core RCM, here's how we handle the specific coding scenarios that drive the most denials and revenue leakage in oncology.
Administration hierarchy documented and coded correctly, chemotherapy before therapeutic infusions before hydration, with concurrent and sequential drug administration captured accurately and start and stop times supporting every time-based code.
HCPCS J-code selection, dosage unit reporting, and JW modifier documentation applied precisely for established chemotherapy agents as well as high-cost biologics, immunotherapy, and CAR-T cell therapy, with reimbursement monitored against acquisition cost under the ASP plus 6% model.
Separate, coordinated coding across every phase of a radiation course, from clinical treatment planning through simulation, physics services, delivery, image guidance, and weekly treatment management, tracked against current payer-specific implementation of the latest code framework.
Biopsies, tumor excisions, and port placements coded where oncology and surgical billing rules intersect, with modifier accuracy applied at every point they overlap.
Orders for hereditary cancer panels, biomarker testing, and companion diagnostics coded and billed to support the treatment decisions they inform, with documentation tied clearly to medical necessity.
Routine costs billed to the patient's insurer and trial-specific costs billed to the sponsor, kept clearly separated so a clinical trial encounter never gets billed against the wrong party.
When a drug is used off-label, the medical necessity documentation has to be stronger than usual to support the claim, and we build that case at the time of treatment rather than reconstructing it after a denial. We also code disease surveillance and survivorship care visits correctly using history-of-malignancy diagnosis codes, so a follow-up visit years after active treatment doesn't get billed, or reimbursed, as if the cancer were still active.
Coverage confirmed for chemotherapy, radiation therapy, PET scans, and targeted treatments before treatment begins, not discovered mid-course.
Authorizations secured and tracked per regimen cycle or per radiation course, with renewals requested ahead of expiration and updates made the same day a regimen changes mid-treatment.
Certified coders apply the correct chemotherapy, infusion, radiation, and surgical oncology codes, with modifier validation, including TC and 26 component splits and incident-to billing rules, built into every claim before it leaves the queue.
Clean claims submitted within 48 hours, with sequencing, bundling, and NCCI edit checks run before a claim ever reaches the payer, not caught after the fact.
Every denied claim reviewed for root cause, whether it's a sequencing error, an authorization gap, a bundling mismatch, or a documentation issue, and appealed with the specific clinical evidence each denial requires.
Proactive follow-up on outstanding balances, with particular attention to high-dollar oncology claims, and unbilled charges worked down as an active queue rather than left to age untouched.
Electronic remittance advice files are posted and reconciled the day they arrive, with underpayment on high-cost drugs flagged immediately rather than discovered in a quarterly review.
Clear, structured patient billing for a population that's often navigating both a cancer diagnosis and a complex insurance picture at the same time.
Enrollment and credentialing with commercial payers, Medicare, and Nevada Medicaid, so new oncologists and new locations never bill against a pending contract.
Most billing companies stop at submitting your claims. We go a level deeper into the specifics that decide whether a Nevada oncology claim gets paid in full and stays paid.
Many oncology procedures bundle into a single code, but treatment regularly varies from the exact bundle. We know what's included and what needs separate billing, so a variation like a different anesthetic or an added service doesn't trigger a denial for duplication, and nothing that should be billed separately gets absorbed silently into the bundle.
Cancer treatment plans shift quickly based on patient response. When a dosage changes or a regimen switches mid-cycle, we update the prior authorization and payer documentation the same day, so the next claim doesn't stall on an authorization mismatch.
Each Medicare Administrative Contractor publishes its own Local Coverage Determinations setting medical necessity standards for specific oncology drugs and procedures, and these vary by jurisdiction. We track the LCDs that apply to your MAC directly, and if a claim ever draws a Recovery Audit Contractor review, your documentation is already built to withstand it rather than assembled after the fact.
CAR-T cell therapy, immunotherapy, targeted biologics, and biosimilars each carry their own coding and prior authorization requirements, and new codes appear as treatments evolve. We stay current on CPT and HCPCS changes as they're published rather than catching up after a claim denies.
We track Nevada Medicaid, Medicare, and commercial payer rules for oncology directly, including authorization thresholds and rate structures specific to the state, rather than applying a generic multi-state template to a Nevada claim.
