How To Use CPT Code 61781

CPT 61781 describes a stereotactic computer-assisted (navigational) procedure for intradural cranial cases. This article will cover the official description, procedure, qualifying circumstances, appropriate usage, documentation requirements, billing guidelines, historical information and billing examples.

1. What is CPT Code 61781?

CPT 61781 can be used to describe a stereotactic computer-assisted (navigational) procedure for intradural cranial cases. This code is used when a provider utilizes a computer navigation system along with CT and/or MRI scans to guide and navigate during intradural cranial procedures. The procedure is performed in high-risk clinical situations that require precise localization and navigational assistance, such as intracranial procedures for brain tumors and vascular malformations.

2. Official Description

The official description of CPT code 61781 is: ‘Stereotactic computer-assisted (navigational) procedure; cranial, intradural (List separately in addition to code for primary procedure).’ It is important to note that this code should not be reported in conjunction with certain other codes, such as 61720-61791, 61796-61799, 61863-61868, 62201, 77371-77373, and 77432.

3. Procedure

1. In this add-on procedure, the provider uses a computer navigation system along with CT and/or MRI scans to guide and navigate during intradural cranial procedures.
2. The provider determines the coordinates for the target by measuring reference lines and calculating angles using a computer.
3. Based on the calculated coordinates, the provider chooses the specific entry point and trajectory through the skull to pinpoint the target.
4. This planning process can take an additional hour or two of the provider’s time.
5. The information obtained during this procedure is then used to assist the provider in performing a primary procedure.
6. CPT code 61781 should be listed separately from the primary procedure.

4. Qualifying circumstances

CPT 61781 is used in high-risk clinical situations that require precise localization and navigational assistance, such as intracranial procedures for brain tumors and vascular malformations. The provider must use a computer navigation system along with CT and/or MRI scans to guide and navigate during the intradural cranial procedure.

5. When to use CPT code 61781

CPT code 61781 should be used when a provider performs a stereotactic computer-assisted (navigational) procedure for intradural cranial cases. It should not be reported if the provider only uses imaging guidance for intraoperative localization.

6. Documentation requirements

To support a claim for CPT code 61781, the provider must document the following information:

• Preplanning activities
• Description of the use of the stereotactic procedure
• Medical necessity for the use of the procedure

7. Billing guidelines

When billing for CPT code 61781, it is important to ensure that the documentation supports the preplanning activities, the description of the use of the stereotactic procedure, and the medical necessity for its use. This code should be listed separately from the primary procedure. Do not report CPT code 61781 in conjunction with certain other codes, as mentioned earlier.

8. Historical information

CPT code 61781 was added to the Current Procedural Terminology system on January 1, 2011. There have been no updates to the code since its addition.

9. Examples

1. A provider performs a stereotactic computer-assisted (navigational) procedure for an intradural cranial case to remove a brain tumor.
2. A patient with a vascular malformation undergoes a stereotactic computer-assisted (navigational) procedure for an intradural cranial case to address the condition.
3. A provider utilizes a computer navigation system along with CT and MRI scans to guide and navigate during an intradural cranial procedure for a patient with a complex brain condition.
4. A provider performs a stereotactic computer-assisted (navigational) procedure for an intradural cranial case to treat a patient with a rare neurological disorder.
5. A patient with a brain tumor undergoes a stereotactic computer-assisted (navigational) procedure for an intradural cranial case to precisely target and remove the tumor.
6. A provider uses a computer navigation system along with CT and MRI scans to guide and navigate during an intradural cranial procedure for a patient with a vascular malformation.
7. A patient with a complex brain condition undergoes a stereotactic computer-assisted (navigational) procedure for an intradural cranial case to address the condition and improve their quality of life.
8. A provider performs a stereotactic computer-assisted (navigational) procedure for an intradural cranial case to treat a patient with a rare neurological disorder and alleviate their symptoms.
9. A patient with a brain tumor undergoes a stereotactic computer-assisted (navigational) procedure for an intradural cranial case to precisely target and remove the tumor, improving their prognosis.
10. A provider utilizes a computer navigation system along with CT and MRI scans to guide and navigate during an intradural cranial procedure for a patient with a vascular malformation, ensuring accurate treatment.
