While you focus on your patients, unpaid claims and coding errors are quietly draining your practice. Quantum’s Oncology Billing services exist for one reason: to make sure every service you provide gets paid. Our Oncology billing expertise covers:
Oncology-specific credentialing and payer enrollment guidance
Compliance with the Oncology Care Model and payer-specific rules
Accurate charge capture for infusion chair time and chemotherapy drug administration
Prior authorizations for chemo regimens and radiation therapy before treatment begins
Denial prevention through precise oncology coding, including HCPCS and ICD-10 specificity
An oncology practice deals with high-cost chemotherapy drugs, complex infusion protocols, cancer staging documentation, and payer rules that change constantly. Here is how Quantum Health Services handles things strategically.
Chemotherapy and Drug Billing: Practices need expert oncology billers to handle frequent coding updates for high-cost drugs.
Prior Authorizations: An oncology billing company secures timely authorizations from insurers to avoid treatment delays and cash-flow disruptions.
Infusion Services Coding: Oncology billers deliver accurate coding to prevent underpayments and close revenue leakage.
ICD-10 Cancer Staging: Specialized billers ensure precise cancer staging documentation to support medical-necessity claims.


Oncology billing changes constantly, and CMS updates reimbursement rules mid-year. ICD-10 codes refresh every October. Payers add their own requirements on top of federal mandates. Missing a single update means denied claims, compliance risks, and lost revenue that your practice cannot easily recover.
Your physicians are trained to treat cancer, not chase coding changes. Outsourcing oncology billing to a specialized medical billing company like Quantum Health Services keeps your claims current, your collections moving, and your practice protected from the compliance exposure that generalist billing always leaves behind.

Before a patient walks in for treatment, we confirm eligibility, investigate benefits, assign the right scheduling codes, and provide upfront financial counseling.

Chemotherapy, immunotherapy, and advanced imaging cannot wait for a slow authorization process. Quantum Health Services secures timely approvals before treatment begins for an uninterrupted cash flow.

We handle Infusion details, Oral oncolytic dispensing, and ICD-10 cancer staging. Every billable service gets captured and coded with the precision oncology claims demand.

We submit clean, payer-specific claims from the start. We act fast and monitor every claim and file rapid appeals to avoid denied oncology treatment claims.

Quantum Health Services manages patient statements clearly and handles buy-and-bill separation and 340B compliance with accuracy.

Outstanding balances do not chase themselves. Quantum Health Services provides aggressive A/R follow-up, KPI dashboards, monthly reconciliations, and transparent reporting.

Our chemotherapy billing specialists handle intravenous chemotherapy, oral oncolytics, wastage documentation, and drug-specific J-codes. Allowing high-cost drug claims to go out clean and come back paid.

Our radiation oncology billing services manage simulation, IMRT, stereotactic procedures, and modality-specific CPTs with a full documentation trail from medical necessity to audit-ready records.

quantum Health Services provides accurate oncology coding for Immune checkpoint inhibitors, infusion administration, and toxicity monitoring visits. Our immunotherapy billing process codes each service accurately and backs every claim with a timely appeals process.

This includes Monoclonal antibodies, targeted agents, and dosing accuracy documentation. Our medical billing for oncology ensures these claims are submitted with the specificity that payers require.

We handle the complex oncology coding, Lymphadenectomy, pathology add-ons, and post-operative care. We capture every billable service so nothing falls through after the procedure is done.

Our advanced diagnostic imaging billing covers PET scans, CT, MRI, nuclear medicine studies, and radiopharmaceuticals. Ensuring the right codes, the right documentation, and the right reimbursement.
Quantum’s oncology billing services providers perform precise coding for diagnostic, surgical, and radiation oncology procedures. Experts at our oncology billing company follow payer rules and the latest oncology coding guidance. Our oncology billing and coding expertise includes, but is not limited to:
IV Chemotherapy administration, up to 1 hour
IV infusion of therapeutic, up to one hour
Radiation treatment management
Stereotactic radiosurgery or radiation therapy
Surgical pathology, commonly used for biopsy
Encounter for antineoplastic chemotherapy
Malignant neoplasm of breast, unspecified
Malignant neoplasm of bronchus, unspecified
Malignant neoplasm of the prostate
Chemotherapy, targeted therapies, and advanced imaging all require pre-authorization. A missed auth means a denied claim. A denied claim means delayed treatment and disrupted cash flow. Quantum Health Services manages the entire prior authorization process from medical-necessity documentation to payer follow-up. So, oncology practices receive faster approvals and fewer denials from day one.
Our dedicated oncology billing team verifies patient benefits, builds evidence-based clinical summaries, and pursues every authorization until payers respond. With integrated EHR workflows and real-time status tracking, your clinicians stay informed, and your patients never wait longer than necessary.

Quantum Health Services is not just another oncology billing company. We work as a direct extension of your oncology practice management. Here is what that means for you:

Our AAPC-certified oncology coders work exclusively on chemotherapy, radiation, and immunotherapy claims to keep your submissions clean and your denials low.

Our real-time dashboards give your practice complete visibility into AR aging, denial rates, and drug-specific collections, so nothing goes untracked.

My husband and I have a small practice but we were looking for a medical billing company to consult us. We originally started with a local company with some satisfaction. However, our biggest problem was that they wanted us to change our existing EMR to software that they worked with. Quantum Health Services worked with our existing software so that we didn't have to make expensive changes to our infrastructure. That saved us a lot of time and headache. I would definitely say that was one of the main reasons for why we switched and why we continue to work with Quantum Health Services. As a small practice, they helped us without draining our resources.
I was just amazed at the quality of service Quantum Health Services was able to provide us. We were exploring two billing companies – one of them was local to our practice and the other was Quantum Health Services. Our Florida-based practice ended up meeting with both firms and we decided to move forward with Quantum Health Services. Honestly I'm unsure if we would've ever found such a reliable partner if it wasn't for them. Thanks to the entire team for helping us through the selection and onboarding process!
As an administrator of a multi specialty clinic, I was looking for a medical billing service near me that provided timely and consistent communication. I found in prior engagements with our prior 2 billing companies neither provided the level of communication or transparency our principals expected. When I was introduced to Quantum Health Services This was a breath of fresh air for me. I could compare solutions without pressure.
The going rate for oncology medical billing services typically falls between 6% and 10% of monthly collections. However, Quantum Health Services offers oncology billing services at just 5%, providing practices with an affordable solution without compromising accuracy.
Yes, Quantum Health Services specializes in providing oncology billing services. Our dedicated cancer billing team is trained in chemotherapy, immunotherapy, radiation therapy, and J-code management. With certified oncology coders and proven denial prevention strategies, we deliver end-to-end revenue cycle solutions fit specifically for oncology practices.
Here’s a list of some of the most common ICD-10 codes used in oncology billing, covering frequently treated cancer types and encounters:
C50.9 — Malignant neoplasm of breast, unspecified
C18.9 — Malignant neoplasm of colon, unspecified
C22.0 — Liver cell carcinoma
C71.9 — Malignant neoplasm of the brain, unspecified
C43.9 — Malignant melanoma of skin, unspecified
Oncology billing experts face unique challenges, such as complex chemotherapy and infusion coding. Other than that, practices have to deal with frequent prior authorization requirements and high-cost drug reimbursement rules. They even struggle with payer-specific policies and ICD-10 staging accuracy, making the need for specialized oncology billers.
Standard billing is straightforward. Chemotherapy billing is not. Every claim needs correct code sequencing, documented start and stop times, and exact drug units. One sequencing error and the whole claim falls apart. Quantum’s oncology billing services make sure that never happens.
The treatment was necessary. The paperwork did not prove it. Missing prior authorizations, mismatched ICD-10 codes, and weak medical necessity documentation are the three biggest denial triggers in oncology. Quantum Health Services catches every one of them before the claim leaves the door.
Audits do not appear out of nowhere. They follow patterns. Quantum Health Services builds real-time alerts, audit trails, and eligibility checks directly into every billing workflow. Problems get flagged before they become findings. Your practice stays protected.
You lose money. Simple as that. High-cost drugs require JW and JZ modifiers to bill every unused unit correctly. Quantum Health Services applies these modifiers precisely and in full compliance with oncology billing guidelines, so not a single dollar gets left behind.
Routine care and research charges cannot mix on the same claim. Ever. Quantum Health Services separates both within oncology medical billing services, billing payers only for covered services. Your revenue stays clean. Your practice stays audit-proof.
Payers want specifics. Infusion times. Drug strength. Units per vial. Vague documentation gets denied. Quantum Health Services documents every infusion detail in line with current oncology billing guidelines so your claims go out complete and come back paid.
