Expertise in oncology billing codes is required for billing specialists to manage the complexity of medical payment. It ensures that healthcare providers are properly compensated for their services while remaining compliant with regulatory standards. By learning oncology billing codes, professionals can improve revenue cycles and overall healthcare practice efficiency.

Types of Oncology Billing Codes

Understanding the various types of oncology billing codes is crucial for billing professionals. These codes ensure that services are billed accurately and efficiently, allowing for proper reimbursement for oncology-related procedures and treatments. Here, we will look at the three primary types of billing codes used in oncology: 

1. CPT Codes

2. ICD-10 Codes

3. HCPCS Codes

CPT codes

Current Procedural Terminology (CPT) codes represent medical, surgical, and diagnostic procedures and are essential in the billing process. CPT codes in oncology cover a wide range of operations such as biopsies, chemotherapy infusions, and radiation therapy sessions. These codes are updated on an annual basis to reflect advancements in medical technology and practice.

List of CPT Codes and Their Description

99203Office visit for the evaluation and management of a new patient, typically 30 minutes

ICD-10 codes

The International Classification of Diseases, Tenth Revision (ICD-10) codes are used to denote diagnoses. In oncology, ICD-10 codes identify the type of cancer being treated. These codes are crucial in determining the medical necessity of the care offered, which influences both treatment strategies and billing.

List of ICD-10 Codes and Their Description

C25.9Malignant neoplasm of pancreas, unspecified
C91.10Chronic lymphocytic leukemia of B-cell type unspecified
C54.1Malignant neoplasm of endometrium

HCPCS codes

Healthcare Common Procedure Coding System (HCPCS) codes are largely used to bill Medicare and Medicaid beneficiaries, and they include products, supplies, and services that CPT codes do not. In oncology, HCPCS codes may be used to bill for medications, particularly those provided as outpatients, such as chemotherapy treatments.

List of HCPCS Codes and Their Description

HCPCS CodeDescription
J9000Doxorubicin hydrochloride, 10 mg (chemotherapy agent)
J9201Gemcitabine HCl, 200 mg, injection (chemotherapy agent)

Common Oncology Billing Code Scenarios

In oncology, billing specialists meet various typical situations in which particular oncology billing codes are used. Understanding how to correctly apply these codes in various treatment contexts is crucial for efficient billing and reimbursement. Discuss four common scenarios: 

  • Chemotherapy Administration¬†
  • Radiation Therapy Services¬†
  • Surgical procedures
  • Evaluation and management (E/M) services

Chemotherapy Administration

Chemotherapy involves numerous steps and treatments that must be accurately coded. The principal CPT codes utilized are those for chemotherapy delivery by infusion (for example, CPT 96413 for up to one hour of intravenous infusion). There are various HCPCS codes, such as J9000 for doxorubicin, that are utilized based on the chemotherapy medicine used. Accurate coding guarantees that all aspects of the treatment is billed correctly.

Example Coding Scenario for Chemotherapy Administration:

  • CPT 96413: Intravenous infusion, chemotherapy, up to 1 hour.
  • HCPCS J9000: Doxorubicin hydrochloride, 10 mg.

Radiation Therapy Services

Radiation therapy services are crucial in cancer, and they require specialized codes that represent the treatment’s complexity and place. CPT 77401 is a common code for simple radiation therapy, although more specific codes are used for more severe scenarios. Each session, planning, and follow-up must be carefully coded to accurately represent the service performed.

Example Coding Scenario for Radiation Therapy Services

  • CPT 77401: Radiation therapy delivered in a single treatment area.

Surgical procedures

Surgical oncology operations range from biopsies to broad resections and are categorized accordingly. CPT codes, such as 19303 for mastectomy, show how individual treatments are directly coded. Surgical coding often includes modifiers to indicate whether numerous procedures are performed within the same operational session.

An example coding scenario for surgical procedures:

  • CPT 19303: Mastectomy, simple, complete.

Evaluation and Management Services

E/M services in oncology include consultations, follow-up visits, and care coordination. These services are categorized according to their complexity and time spent with the patient. CPT 99203 is a typical code for a new patient office visit, and it varies depending on the specifics of the history, examination, and medical decision-making.

An example coding scenario for E/M services:

  • CPT 99203: Office visit for the evaluation and care of a new patient, which requires the following three components: A detailed history; a thorough examination; and low-complexity medical decisions.
