How To Use CPT Code 92145

CPT 92145 describes the procedure for corneal hysteresis determination, which involves measuring the difference in inward and outward movement of the cornea using air impulse stimulation. This article will cover the description, procedure, qualifying circumstances, appropriate usage, documentation requirements, billing guidelines, historical information, similar codes and billing examples.

1. What is CPT Code 92145?

CPT 92145 can be used to describe the procedure for corneal hysteresis determination. This involves measuring the difference in inward and outward movement of the cornea by applying metered air impulses on one or both eyes. The provider then interprets the data and completes a report on the findings.

2. Official Description

The official description of CPT code 92145 is: ‘Corneal hysteresis determination, by air impulse stimulation, unilateral or bilateral, with interpretation and report.’

3. Procedure

1. The provider uses an ocular response analyzer, a device designed to measure corneal hysteresis.
2. The device connects to software that displays and records the difference in pressure during eye movement.
3. The provider applies pressure over the cornea through metered air pulses, causing the cornea to deform and move inward.
4. As the provider lowers the air pulse force, the cornea begins to regain its normal shape.
5. An infrared beam measures changes in the shape of the cornea during inward and outward movement.
6. The provider interprets the different responses to air pressure during inward and outward movement and reports any abnormality detected.
7. This procedure can be performed on one eye or both eyes, one after the other.

4. Qualifying circumstances

CPT 92145 is performed when there is a need to determine corneal hysteresis. This procedure is typically done for patients who may have abnormalities or conditions affecting the cornea. The provider must use an ocular response analyzer and interpret the data to report any abnormal findings.

5. When to use CPT code 92145

CPT code 92145 should be used when there is a need to measure corneal hysteresis using air impulse stimulation. It is important to ensure that the procedure is performed with the appropriate equipment and that the provider is able to interpret and report the findings accurately.

6. Documentation requirements

To support a claim for CPT 92145, the provider must document the following information:

• Reason for performing the corneal hysteresis determination
• Details of the procedure, including whether it was performed on one eye or both eyes
• Interpretation of the data and any abnormal findings
• Completion of a report summarizing the findings

7. Billing guidelines

When billing for CPT 92145, it is important to ensure that the procedure is performed according to the official description. The provider should use the appropriate code for unilateral or bilateral determination and include the interpretation and report. It is also important to follow any specific billing guidelines provided by the payer.

8. Historical information

CPT 92145 was added to the Current Procedural Terminology system on January 1, 2015. There have been no updates to the code since its addition.

9. Examples

1. A provider performs corneal hysteresis determination on a patient with suspected corneal abnormalities.
2. During a routine eye examination, the provider measures corneal hysteresis using air impulse stimulation to assess the patient’s eye health.
3. A patient with a history of corneal disease undergoes corneal hysteresis determination to monitor any changes in corneal function.
4. As part of a pre-operative evaluation, the provider performs corneal hysteresis determination to assess the patient’s suitability for a specific eye surgery.
5. A patient with a family history of corneal abnormalities undergoes corneal hysteresis determination as a preventive measure.
6. A provider performs corneal hysteresis determination on both eyes of a patient to compare the findings and identify any discrepancies.
7. During a follow-up visit, the provider repeats corneal hysteresis determination to monitor the progress of a patient’s corneal condition.
8. A patient with a recent eye injury undergoes corneal hysteresis determination to assess the impact on corneal function.
9. A provider performs corneal hysteresis determination on a patient with a history of contact lens use to evaluate the effects on corneal health.
10. As part of a comprehensive eye examination, the provider includes corneal hysteresis determination to assess the overall eye health of the patient.
