How To Use CPT Code 61340

CPT 61340 describes the subtemporal cranial decompression procedure used to relieve intracranial pressure in patients with conditions such as pseudotumor cerebri and slit ventricle syndrome. This article will cover the description, official description, procedure, qualifying circumstances, appropriate usage, documentation requirements, billing guidelines, historical information and billing examples.

1. What is CPT Code 61340?

CPT 61340 is a code used to describe the subtemporal cranial decompression procedure. This procedure involves the removal of part of the skull beneath the temporal muscle and opening the dura to relieve intracranial pressure. It is typically performed in patients with conditions such as pseudotumor cerebri and slit ventricle syndrome.

2. Official Description

The official description of CPT code 61340 is: ‘Subtemporal cranial decompression (pseudotumor cerebri, slit ventricle syndrome).’

3. Procedure

1. The provider begins by making an incision in the scalp over the subtemporal area that needs to be decompressed.
2. They then fold back the tissue to expose the bone and use a surgical drill, saw, and a tool with a footplate to protect the dura.
3. A burr hole or holes are created in the skull using the drill, and the provider cuts between adjacent holes to create a bone flap.
4. The bone flap is then removed to expose the dura, and any bleeding from bone edges is stopped using bone wax.
5. Once the dura is opened and the pressure is relieved, the bone flap is replaced and secured with permanent plates, wires, and screws.
6. The tissue flap is folded back, the scalp is closed, and a sterile dressing is applied.

4. Qualifying circumstances

CPT 61340 is typically performed in patients with conditions such as pseudotumor cerebri and slit ventricle syndrome. These conditions are characterized by increased intracranial pressure for no obvious reason or as a complication of shunt implantation for excess cerebrospinal fluid buildup in the ventricles of the brain. The procedure is performed by a provider to decompress the area of the brain below the temples and relieve the pressure.

5. When to use CPT code 61340

CPT code 61340 should be used when the subtemporal cranial decompression procedure is performed to relieve intracranial pressure in patients with conditions such as pseudotumor cerebri and slit ventricle syndrome. It is important to ensure that the procedure is performed by a qualified provider and meets the specific criteria outlined in the code description.

6. Documentation requirements

To support a claim for CPT 61340, the provider must document the following information:

• Diagnosis of pseudotumor cerebri or slit ventricle syndrome
• Description of the procedure performed, including the specific location and approach
• Date of the procedure
• Start and end time of the procedure
• Any complications or additional procedures performed
• Signature of the provider performing the procedure

7. Billing guidelines

When billing for CPT 61340, ensure that the procedure meets the specific criteria outlined in the code description. It is important to use the appropriate modifier if the procedure is performed bilaterally. Additionally, be aware of any Medicare changes or specific billing guidelines that may apply to this code.

8. Historical information

CPT 61340 was added to the Current Procedural Terminology system on January 1, 1990. There have been historical changes to the code, including the addition of the code to the Inpatient Only (IPO) list in 2017.

9. Examples

1. A patient with pseudotumor cerebri undergoes subtemporal cranial decompression to relieve intracranial pressure.
2. A provider performs subtemporal cranial decompression on a patient with slit ventricle syndrome to alleviate symptoms.
3. A surgical team performs subtemporal cranial decompression on a patient with pseudotumor cerebri, using a bilateral approach with modifier 50.
4. A provider performs subtemporal cranial decompression on a patient with slit ventricle syndrome, documenting the specific location and approach in the procedure report.
5. A patient with pseudotumor cerebri undergoes subtemporal cranial decompression, and the procedure is performed by a qualified neurosurgeon.
6. A provider performs subtemporal cranial decompression on a patient with slit ventricle syndrome, documenting the start and end time of the procedure.
7. A patient with pseudotumor cerebri undergoes subtemporal cranial decompression, and the procedure is performed without any complications.
8. A provider performs subtemporal cranial decompression on a patient with slit ventricle syndrome, and additional procedures are performed during the same surgical session.
9. A surgical team performs subtemporal cranial decompression on a patient with pseudotumor cerebri, and the procedure is signed by the neurosurgeon.
10. A provider performs subtemporal cranial decompression on a patient with slit ventricle syndrome, and the procedure is billed according to the specific billing guidelines for CPT 61340.
