Important Disciplines of Oncology

Oncology is the field of medicine that deals with the diagnosis, prevention, and treatment of Cancer. It deals in several specialized areas. These include Surgical Oncology, Radiation Oncology, and Medical Oncology.

Surgical Oncology

Surgical Oncology focuses on using surgery as a treatment method for Cancer. Surgical oncologists perform procedures to remove cancerous tumors and assess the extent of damage that Cancer has made. They work closely with primary care physicians to develop treatment plans and conduct diagnostic biopsies. Surgical oncology plays an imperative role in healthcare. These include cancer prevention, cancer diagnosis and staging, curative surgery, tumor reduction, and supportive procedures. It also deals with palliative surgery to relieve cancer symptoms and reconstructive surgery to restore the appearance and function of affected body parts.

Radiation Oncology

Radiation Oncology is a medical discipline that uses radiation therapy for cancer treatment. This therapy involves the use of X-rays to destroy or shrink tumors. Radiation therapy can be used as a primary treatment or it can also be used in conjunction with other treatments. It may be used before or after surgery to reduce tumor size and inhibit cancer cell growth.

There are number of other objectives of using radiation therapy. For instance, it includes curing Cancer, halting the growth and spread of cancer cells, reducing tumor size, supporting other cancer treatments, and alleviating cancer symptoms. However, radiation therapy may have side effects as well. For instance, the major side effects include damage to normal cells, fatigue, skin issues, mouth or throat discomfort, breathing difficulties, nausea, loss of appetite, and cough.

Medical Oncology

Medical Oncology is a specialized field that addresses cancer diagnosis, prevention, and treatment by using various modalities. These include chemotherapy, targeted therapies, hormonal therapy, immunotherapy, and more. Medical oncologists often serve as primary care physicians for cancer patients. Medical oncologists are responsible for supervising entire treatment plans, collaborating with other specialists, and monitoring patient responses.

Types of Cancers

Non-Melanoma Skin Cancer

Non-melanoma Skin Cancer includes basal cell carcinoma and squamous cell carcinoma. It is the most prevalent form of Cancer in the United States. It affects over a million Americans annually. The exact number of cases is often under reported because it can regularly be managed at hospitals.

Basal Cell Carcinoma

The Signs of basal cell carcinoma specifically involve sores that do not heal or reappear after healing. It causes raised scaly red patches, small shiny, smooth lumps in pink, red, or white, pale flat areas resembling scars. These might also result in bleeding, itching growths, and pink growths with raised edges. This type of Cancer mainly develops on the head, face, neck, and torso.

Squamous Cell Carcinoma

The Signs of squamous cell carcinoma specifically involve scaly red patches with uneven borders. This may also result in wart-like growths, sores that bleed easily and form persistent crusts that cause itching, irritation, or pain. It normally occurs on sun-exposed areas, such as the face.

Breast Cancer Breast

Cancer affects both women and men. Significant Signs of breast cancer include the discovery of a new lump in the breast, armpit, or around the collarbone. It also results in breast size or shape changes, skin irritation, and dimpling. Some patients have reported thickening of breast skin, redness, breast or nipple pain, and nipple discharge other than breast milk. It is important to note that not all breast lumps are cancerous. However, if any changes are observed, they should be evaluated by a healthcare professional.

Lung Cancer

Lung Cancer is a matter of serious concern. Its signs may include a persistent cough that worsens over time. It may also result in coughing up blood and experiencing shortness of breath, chest pain, bone pain, and hoarseness. In some patients, this has also caused recurrent lung infections like pneumonia, unintentional weight loss, loss of appetite, frequent headaches, and blood clots. It has been observed that Lung cancer often doesn’t show symptoms until it reaches an advanced stage. It is therefore recommended to pay close attention on any of the above mentioned symptoms.

Prostate Cancer

Prostate Cancer mainly affects men. The Signs of prostate cancer can include urinary problems like difficulties with urination. It might also cause trouble in starting or stopping urination, urinary leakage, and a sudden uncontrollable urge to urinate. Some patients have reported pain or burning sensation during urination, frequent urination, and maintaining an erection because of this type of Cancer. It may also affect the ejaculation, such as pain or reduced fluid during ejaculation. The presence of blood in urine, pain in the lower back, thighs, hips, or pelvic area, and discomfort in the rectum are key symptoms of this Cancer. Men having age around 55 years are most likely to be affected by this Cancer.

Colon and Rectal Cancers

Colon and Rectal Cancers are also significant health concerns. Their signs may involve unexplained weight loss, weakness, and changes in bowel habits like persistent constipation. It can also cause diarhea and abdominal pain that may come and go but lasts for an extended period. The rectal pressure and the sensation of bowel movement are also its symptoms. These cancers may not cause symptoms until they reach an advanced stage.


Melanoma is a type of skin cancer. It is characterized by specific signs such as moles or marks on the skin that exhibit irregularity with uneven edges. It may appear in a variety of colors within the mole. For instance, it may appear as larger moles exceeding the size of a pencil eraser, moles that change rapidly in size or color, and moles with developed crusts.

Bladder Cancer

The primary sign of this Cancer is blood in the urine. It often causes it to appear pink, red, or orange. Other urinary changes are trouble urinating, a weak urine stream, pain during urination, or the inability to urinate. These symptoms should be assessed by a healthcare provider. Keep in mind that similar symptoms can be caused by non-cancerous conditions like urinary tract infections, overactive bladder, or an enlarged prostate. It is therefore recommended to take an expert opinion before going through medication.

Non-Hodgkin’s Lymphoma

Non-Hodgkin’s Lymphoma is a type of Cancer characterized by signs like enlarged lymph nodes. This might result in unexplained weight loss, persistent weakness or fatigue, fever, night sweats, and abdominal swelling.

Oncology medical billing and coding Challenges

Determining the Accurate Codes

Oncology medical billing and coding involves unique challenges that make it different from other medical fields. Coders must deal with distinct guidelines to select the appropriate codes. Using the correct medical codes is crucial. Because it ensures that insurance carriers accept and reimburse oncology practices timely. On the other hand, submitting claims with incorrect codes can lead to claim rejections. It can also result in triggering prolonged interactions between billers and payers to resolve the issues. For instance, the administration of chemotherapy requires multiple codes. Each of these codes represents different degrees of severity. If these issues are not addressed properly by using the correct code, then it might lead to claim denials and payment delays.

Exercising Precision

The lack of diligence is a common reason that allows insurance providers to reject oncology claims. Coders frequently work with procedures that closely resemble each other. When claims lack important details, and there is no proper supporting documentation for the submitted claim, the insurance company may challenge the claim. This leads to delays in payment collection or can also result in claim dejection. Precision in coding is a matter of great concern. For that reason, a comprehensive understanding of the terminology used by oncologists is essential for accuracy. The AAPC emphasizes the significance of language comprehension in ICD-10-CM coding. Medical coders should be familiar with the terminologies used by patients, doctors, and payers for accurate coding.

Utilizing Specific Language

The use of Specific language also plays a critical role in oncology medical billing and coding. This especially works when dealing with malignancies. Determining whether a condition is “active” or “a history of” is a matter of great concern. In such cases, the key terms help coders to specify the status. The possible statuses can be “current,” “adjuvant,” “history,” “debulked,” and “removed/eradicated .”Coders should exercise caution when documenting diagnoses. He must avoid uncertain terms like “suspected,” “questionable,” “likely,” “possible,” “presumed,” and “consistent with,”. All these terms are subjective and do not qualify as definitive diagnoses.

Ensuring Compliance with Current Oncology Medical Billing And Coding Rules

Ensuring compliance with the current oncology medical billing and coding rule is a matter of success. However, balancing between ‘revenue optimization’ and ‘adherence to regulations’ is another challenge faced by oncology institutions. Inaccurate oncology medical billing and coding due to outdated and erroneous codes can result in fines. Such practices can also lead to legal consequences. It doesn’t matter if the errors occur deliberately or accidentally; such inaccuracies lead to claim denials and financial implications. For that reason, it is imperative to stay updated with the latest coding rules.

Oncology medical billing and coding guidelines

In the realm of medical technology networks, oncology medical billing and coding rely heavily on specific codes. These codes fall into three main systems: the International Classification of Diseases Clinical Modification (ICD-10-CM), Current Procedural Terminology (CPT), and the Healthcare Common Procedure Coding System (HCPCS).

These coding systems are important components of oncology medical billing guidelines. These rules and guidelines are controlled by the Health Insurance Portability and Accountability Act (HIPAA), enacted in 1996 to establish health information standards. That is the reason, the healthcare providers must strictly adhere to HIPAA rules and regulations to avoid significant fines.


ICD-10-CM is a systematic medical coding framework used by healthcare providers to document and process medical claims. It focuses on classifications for diagnoses, symptoms, medical conditions, and external causes of injuries. ICD-10-CM codes have evolved to align with updates from the World Health Organization that were originally developed to catalog health conditions. Examples of ICD-10-CM codes include M54.2 for cervicalgia and G44.311 code for intractable acute post-traumatic headache.


CPT codes are numeric or alphanumeric identifiers assigned to diagnostic, surgical, and medical services provided by healthcare practitioners. These codes are essential for monitoring and oncology medical billing. For instance, these codes are used for calculating reimbursement amounts from insurers. The American Medical Association (AMA) manages CPT codes. It is responsible for updating them regularly to reflect changes in healthcare practices. Examples of CPT codes include 90658 for a flu shot and 99214 for an office visit.


HCPCS is developed by CMS in the 1980s. It plays a crucial role in oncology medical billing processes. It can also play a crucial part, particularly in the context of Medicare. It consists of three tiers of alphanumeric codes. Level I resembles CPT and is used for Medicare and Medicaid claims. Level II codes identify medical services, supplies, and products not covered by CPT codes. Level III codes are also known as local codes. These codes are specific to certain areas and items outside Levels I and II. Examples of HCPCS codes include G0008 for temporary procedures, R0070 for diagnostic radiology services, and E0100 for durable medical equipment.
