How To Use CPT Code 0198T

CPT 0198T describes the measurement of ocular blood flow by repetitive intraocular pressure sampling, with interpretation and report. This article will cover the description, procedure, qualifying circumstances, appropriate usage, documentation requirements, billing guidelines, historical information, and examples.

1. What is CPT Code 0198T?

CPT 0198T can be used to measure ocular blood flow by repetitive intraocular pressure sampling, with interpretation and report. This code is specifically used for patients with glaucoma, as the data obtained from this procedure is valuable in assessing their condition.

2. Official Description

The official description of CPT code 0198T is: ‘Measurement of ocular blood flow by repetitive intraocular pressure sampling, with interpretation and report.’

3. Procedure

1. The provider applies an anesthetic eye drop to the patient’s eye.
2. Using an ocular blood flow tonometer, the provider measures the intraocular pressure and pulsatile ocular blood flow.
3. The tonometer can measure the pressure roughly 200 times in a second, allowing for accurate assessment.
4. The provider interprets the values of the ocular blood flow using a computer.
5. A report is then completed, summarizing the findings of the measurement and interpretation.

4. Qualifying circumstances

CPT 0198T is used for patients with glaucoma, an eye disorder characterized by increased intraocular pressure. The procedure is performed by a provider who measures the ocular blood flow using a tonometer and interprets the values obtained. It is important to note that this code is specific to the measurement of ocular blood flow and should not be used for other purposes.

5. When to use CPT code 0198T

CPT code 0198T should be used when there is a need to measure ocular blood flow in patients with glaucoma. It is not appropriate to use this code for other conditions or for general intraocular pressure measurements. It is important to accurately document the medical necessity for this procedure and ensure that it aligns with the patient’s diagnosis of glaucoma.

6. Documentation requirements

To support a claim for CPT code 0198T, the provider must document the following information:

• Patient’s diagnosis of glaucoma
• Details of the measurement procedure, including the use of an ocular blood flow tonometer
• Date and time of the procedure
• Interpretation of the ocular blood flow values
• Completion of a report summarizing the findings

7. Billing guidelines

When billing for CPT code 0198T, ensure that the procedure is performed for patients with glaucoma and that the documentation supports the medical necessity. This code should not be reported with other codes unless there are specific circumstances that warrant it. It is important to follow the guidelines provided by the payer and submit accurate and detailed documentation to support the claim.

8. Historical information

CPT code 0198T was added to the Current Procedural Terminology system on January 1, 2010. There have been no updates or changes to the code since its addition.

9. Examples

1. A provider measures ocular blood flow using repetitive intraocular pressure sampling and interprets the values for a patient diagnosed with glaucoma.
2. Using an ocular blood flow tonometer, a provider assesses the pulsatile ocular blood flow in a patient with glaucoma and completes a report on the findings.
3. For a patient with glaucoma, a provider measures the intraocular pressure and interprets the ocular blood flow values obtained through repetitive sampling.
4. A provider performs repetitive intraocular pressure sampling to measure ocular blood flow in a patient diagnosed with glaucoma and provides an interpretation of the results.
5. Using a tonometer, a provider measures the ocular blood flow in a patient with glaucoma and documents the findings in a report.
6. For a patient with glaucoma, a provider assesses the pulsatile ocular blood flow using repetitive intraocular pressure sampling and provides an interpretation of the measurements.
7. A provider measures the intraocular pressure and interprets the ocular blood flow values obtained through repetitive sampling for a patient diagnosed with glaucoma.
8. Using an ocular blood flow tonometer, a provider evaluates the pulsatile ocular blood flow in a patient with glaucoma and completes a report summarizing the findings.
9. For a patient with glaucoma, a provider performs repetitive intraocular pressure sampling to measure ocular blood flow and provides an interpretation of the results.
10. A provider measures the ocular blood flow using a tonometer and interprets the values obtained through repetitive intraocular pressure sampling for a patient diagnosed with glaucoma.
