Brain Mass ICD-10-CM Codes | 2023

What ICD-10 Codes are Used for Brain Mass? 

A brain mass is an abnormal growth or tumor in the brain that can have various causes and require different treatments. The International Classification of Diseases, Tenth Revision (ICD-10), provides a standardized system for coding diagnoses, including brain mass conditions. Here are some commonly used ICD-10 codes for brain mass, along with their clinical descriptions:

D33.0 - Benign Neoplasm of Brain, Supratentoria: 

This code is used to classify non-cancerous brain tumors located in the supratentorial region. These tumors usually have a slow growth rate and do not invade surrounding tissues.

D33.1 - Benign Neoplasm of Brain, Infratentorial:

This code is used for benign brain tumors located in the infratentorial region. These tumors can affect the cerebellum, brainstem, or other structures below the tentorium.

C71.0 - Malignant Neoplasm of Brain, Supratentorial:

This code is used for malignant (cancerous) tumors in the supratentorial region of the brain. These tumors can grow rapidly, invade nearby tissues, and may require aggressive treatment approaches.

C71.1 - Malignant Neoplasm of Brain, Infratentorial:

This code is used to classify malignant brain tumors located in the infratentorial region. These tumors can be aggressive and may cause symptoms related to the compression of vital structures in the lower part of the brain.

C71.7 - Malignant Neoplasm of Overlapping Sites of Brain:

This code is used when the malignant brain tumor does not have a specific supratentorial or infratentorial location but involves overlapping regions. It may require further specifications based on the exact location.

D32.0 - Benign Neoplasm of Meninges:

Used for non-cancerous tumors that develop in the meninges, which are the protective membranes covering the brain and spinal cord. These tumors can cause symptoms such as headaches or changes in neurological function.

C70.0 - Malignant Neoplasm of Cerebral Meninges:

This code is used for malignant tumors originating in the cerebral meninges. These tumors can be invasive and require a multidisciplinary approach for treatment, including surgery, radiation, and chemotherapy.

D42.0 - Neoplasm of Uncertain Behavior of Brain:

Used when there is a brain mass with uncertain behavior, meaning it is difficult to determine whether it is benign or malignant. Further diagnostic testing and monitoring may be required to make an accurate diagnosis.

D43.0 - Neoplasm of Uncertain Behavior of Meninges:

Similar to D42.0, D43.0 is used when there is uncertainty regarding the behavior of a tumor located in the meninges. Close observation and additional testing may be necessary to determine the appropriate action.

C79.31 - Secondary Malignant Neoplasm of Brain:

This ICD-10 code is used when a brain mass is a secondary tumor resulting from the spread (metastasis) of cancer from another primary site in the body. Primary cancer should be coded separately.

Which Brain Mass ICD codes are Billable: 

D33.0 - Benign Neoplasm of Brain, Supratentorial:

Yes, this code is usually billable. It represents a specific diagnosis of a benign brain tumor in the supratentorial region, which requires medical attention and potential treatment.

D33.1 - Benign Neoplasm of Brain, Infratentorial: 

Yes, this code is typically billable. It denotes a benign brain tumor in the infratentorial region, necessitating medical evaluation and management.

C71.0 - Malignant Neoplasm of Brain, Supratentorial: 

Yes, this code is billable. It indicates a malignant brain tumor in the supratentorial region, which requires extensive medical intervention, such as surgery, radiation, or chemotherapy.

C71.1 - Malignant Neoplasm of Brain, Infratentorial: 

Yes, this code is generally billable. It represents a malignant brain tumor in the infratentorial region, requiring significant medical attention and treatment.

C71.7 - Malignant Neoplasm of Overlapping Sites of Brain: 

Yes, this code is usually billable. It signifies a malignant brain tumor that involves overlapping regions, necessitating comprehensive medical management.

D32.0 - Benign Neoplasm of Meninges: 

Yes, this code is typically billable. It refers to a benign tumor in the meninges, which requires medical evaluation and possibly intervention.

C70.0 - Malignant Neoplasm of Cerebral Meninges: 

Yes, this code is billable. It denotes a malignant tumor in the cerebral meninges, which necessitates extensive medical treatment and management.

D42.0 - Neoplasm of Uncertain Behavior of Brain: 

Yes, this code is usually billable. It represents a brain mass with uncertain behavior, requiring medical attention and ongoing observation to determine its nature.

D43.0 - Neoplasm of Uncertain Behavior of Meninges: 

Yes, this code is typically billable. It indicates a tumor in the meninges with uncertain behavior, requiring medical evaluation and ongoing monitoring.

C79.31 - Secondary Malignant Neoplasm of Brain: 

Yes, this code is generally billable. It signifies a secondary malignant tumor in the brain resulting from metastasis, necessitating medical attention and treatment. However, primary cancer should be coded separately.

Clinical Information

When it comes to brain masses, clinical information plays a crucial role in understanding and managing these conditions effectively. Here are some key points to consider:

• Brain masses can encompass various conditions, including benign and malignant tumors and other abnormal growths in the brain or its surrounding structures.
• Clinical evaluation of a brain mass involves thoroughly assessing the patient's medical history, neurological symptoms, and physical examination findings.
• Diagnostic imaging techniques such as magnetic resonance imaging (MRI), computed tomography (CT), or positron emission tomography (PET) scans are commonly used to visualize and characterize brain masses.
• Histopathological analysis of a tissue sample obtained through biopsy or surgical resection is often necessary to determine the precise nature of the brain mass, whether it is benign or malignant, and to guide further treatment decisions.
• The symptoms and consequences of brain masses can vary significantly depending on their size, location, and aggressiveness. Common symptoms may include headaches, seizures, cognitive changes, motor or sensory deficits, and alterations in mood or behavior.
• Treatment options for brain masses may include surgery, radiation therapy, chemotherapy, targeted therapies, or a combination of these modalities. The choice of treatment depends on factors such as the type and grade of the tumor, its location, the patient's overall health, and individualized treatment goals.
• Close monitoring and follow-up care are crucial for individuals diagnosed with a brain mass to assess treatment response, manage potential side effects or complications, and detect any recurrence or progression of the condition.
