What ICD-10 Codes Are Used for Mass Brain?

A "brain mass" typically refers to a tumor or other abnormal growth in the brain. The ICD-10-CM system includes several mass brain ICD codes for different types and locations.

D33.0 - Benign neoplasm of brain, supratentorial: This code is used when the benign mass is above the tentorium, a membrane separating two brain parts.
D33.1 - Benign neoplasm of brain, infratentorial: When the benign mass is below the tentorium.
C71.9 - Malignant neoplasm of brain, unspecified: Used when the mass is a malignant tumor but its specific location is not indicated.
C71.0 - Malignant neoplasm of the cerebrum, except lobes and ventricles: For malignant tumors in the cerebrum, excluding specific regions.
C71.5 - Malignant neoplasm of the cerebral ventricles: When the malignant mass is in the cerebral ventricles.
C71.6 - Malignant neoplasm of the cerebellum: For malignant tumors in the cerebellum.

Which Mass Brain ICD Codes Are Billable?

Whether a code is billable depends on the case's specifics and the insurance company's policies.

D33.0 - Yes, this code for a benign supratentorial brain mass is billable.
D33.1 - Yes, this is billable for a benign infratentorial brain mass.
C71.9 - Yes, this code is billable for an unspecified malignant brain tumor.
C71.0 - Yes, this is billable for a malignant tumor in the cerebrum (excluding lobes and ventricles).
C71.5 - Yes, it is billable for a malignant tumor in the cerebral ventricles.
C71.6 - Yes, it is billable for a malignant tumor in the cerebellum.

Clinical Information

A brain mass can refer to any abnormal growth located in the brain, including benign (non-cancerous) and malignant (cancerous) tumors.

These masses can arise from brain cells, the membranes surrounding the brain (meninges), nerves, or glands.
Symptoms vary depending on the mass's size and location but can include headaches, seizures, and neurological deficits.
Risk factors include exposure to radiation, family history of brain tumors, and certain inherited conditions.
Diagnosis usually involves imaging tests like CT or MRI scans.
Treatment options can include surgery, radiation therapy, and chemotherapy, depending on the mass's nature.

Synonyms Include:

Brain Tumor
Brain Neoplasm
Intracranial Mass
Cerebral Mass
Brain Lesion

Commonly asked questions

Symptoms of a brain mass can include headaches, seizures, vision problems, balance issues, behavioral changes, and neurological deficits, depending on the mass's location and size.

Treatment for a brain mass depends on the mass's type, size, location, and the patient's overall health. It may involve surgery, radiation therapy, chemotherapy, or a combination.

Yes, a brain mass can be benign or non-cancerous. However, even benign brain masses can cause serious problems depending on their location and if they put pressure on surrounding brain tissue.
