CPT Code 61770 | Description & Clinical Information
CPT 61770 describes the process of removing a section of the skull bone and inserting a catheter or probe into a brain lesion using mapped coordinates obtained from CT and/or MRI scans to accurately place a radiation source.
Official Description
The CPT book defines CPT code 61770 as: “Stereotactic localization, including burr hole(s), with insertion of catheter(s) or probe(s) for placement of radiation source”.
Clinical Information
The procedure describes by CPT code 61770 involves a complex process of locating and treating intracranial tumors. It requires the patient to be appropriately prepped and anesthetized before the provider can begin the procedure.
The provider uses coordinates obtained from CT or MRI scans of the brain to guide him in locating the site of the intracranial tumor. These imaging studies map the precise location of the lesion, providing the provider with essential information needed to locate the site and place a radiation source. Depending on the type of radiation source, the implants may be temporary or permanent.
To begin the procedure, the provider incises the scalp over the mapped location and retracts the scalp to expose the bone. The next step is to use a surgical drill to create a burr hole and incises the dura. The provider then proceeds to insert a catheter or hollow probe to the targeted depth, utilizing the coordinates from the scan to ensure accuracy.
Once the catheter or probe is in place, the provider places the radiation source, usually seeds or pellets, through the catheter or probe directly into the tumor bed. It is crucial to ensure the positioning accuracy of the radiation source since the surrounding tissue could be damaged if the provider misses the target.
After placing the radiation source, the provider removes the catheter or probe and closes the dura. The tissue layers are then reapproximated, the scalp is sutured, and sterile dressings are applied to prevent infection.
The procedure is a delicate process that requires precision and accuracy. The provider must practice caution, especially when dealing with intracranial tumors. The procedure aims to destroy the tumor cells while minimizing damage to the surrounding healthy brain tissue.
The CPT code 61770 is essential because it enables proper documentation of the procedure and allows easy tracking of the procedure’s frequency. The procedure is covered under insurance plans, making it an affordable treatment option for intracranial tumors.
In conclusion, the CPT code 61770 procedure is a vital treatment option for intracranial tumors. It requires the use of imaging studies, such as CT and MRI scans, for accuracy, which guides the provider in locating the site of the tumor. The procedure is delicate and requires the provider to exercise caution while placing the radiation source to avoid damage to the surrounding healthy brain tissue. With this procedure, patients can have more options for treating intracranial tumors, and with proper documentation using the CPT code 61770, the procedure can be easily tracked and covered under insurance plans.
