Oncology Medical Billing Services
Oncology billing revolves around high-cost chemotherapy and infusion administration, complex drug J-code accuracy, and prior authorizations that can delay treatment if mishandled. CoreStone's oncology-trained billing team keeps infusion, radiation, and surveillance claims clean and on schedule.
Billing That Understands Oncology
From chemotherapy infusion to radiation therapy and long-term surveillance, oncology practices bill a mix of high-cost drug administration and E/M services — each with its own J-code, unit-conversion, and prior-authorization requirements. Our coders and billers are trained specifically on the codes and payer rules unique to cancer care.
- ICD-10 coding for malignant neoplasms across every stage & site
- CPT/HCPCS coding for chemotherapy infusion, injection & radiation therapy
- J-code drug billing with correct units, waste modifiers & NDC reporting
- Prior authorization support for chemotherapy regimens & specialty drugs
- Denial review for bundled infusion, drug, and E/M same-day visits

Caring Revenue Cycle Management For Oncology Practices
Oncology practices are under constant pressure to raise the standard of care while facing reduced reimbursement, growing regulatory risk, and thinner margins. Maximizing your revenue cycle — billing, coding, and accounts receivable — is essential to keeping up with an increasingly complex payer landscape.
CoreStone is committed to offering the best oncology billing services available, covering nearly every aspect of the billing and patient revenue cycle. We work to secure the fastest possible reimbursement for your practice — the sooner a clean claim goes out, the sooner you get paid. That's why our billing experts are on call around the clock, working while you sleep.

That's why our oncology billing solutions are highly personalized, giving your practice real autonomy over its finances and workflow while we handle the coding, claims, and collections behind the scenes.
