CPT® Code 0329T

1. Indications

The monitoring of intraocular pressure using CPT® Code 0329T is indicated for the assessment of conditions that may affect intraocular pressure, particularly in patients at risk for glaucoma or other ocular hypertension-related disorders. This procedure is essential for patients who exhibit symptoms or have a history suggestive of elevated intraocular pressure, as well as those requiring ongoing monitoring to evaluate the effectiveness of treatment strategies.

• Glaucoma Risk Patients who are at risk for developing glaucoma due to family history, age, or other risk factors.
• Ocular Hypertension Individuals with elevated intraocular pressure that requires monitoring to prevent potential damage to the optic nerve.
• Post-Surgical Monitoring Patients who have undergone ocular surgery and need to monitor intraocular pressure as part of their recovery process.

2. Procedure

The procedure for monitoring intraocular pressure using CPT® Code 0329T involves several key steps that ensure accurate data collection and analysis.

• Step 1: Patient Preparation The patient is prepared for the procedure during an outpatient visit. This includes a thorough examination of the eye to ensure that the patient is a suitable candidate for the contact lens monitoring system.
• Step 2: Insertion of the Contact Lens A soft, hydrophilic, single-use contact lens with an embedded pressure sensor is carefully inserted into the patient's eye. The physician or eye care professional ensures that the lens is positioned correctly to facilitate accurate pressure readings.
• Step 3: Activation of the Device Once the contact lens is in place, the device is activated. This step is crucial as it initiates the monitoring process, allowing the pressure sensor to begin detecting fluctuations in intraocular pressure.
• Step 4: Data Transmission The pressure sensor within the contact lens detects circumferential changes at the corneoscleral junction, which correlate to intraocular pressure. These readings are wirelessly transmitted to an antenna that is affixed around the eye with a circular adhesive.
• Step 5: Data Recording The antenna is connected to a portable recording unit that captures the intraocular pressure data over the monitoring period of 24 hours or longer. This data is stored for subsequent analysis.
• Step 6: Data Download and Interpretation After the monitoring period, the physician or eye care professional downloads the recorded data to a computer program. This allows for detailed analysis and interpretation of the intraocular pressure readings.
• Step 7: Reporting and Treatment Planning Finally, the physician interprets the data collected, reports the results to the patient, and formulates an optimal treatment plan based on the findings.

3. Post-Procedure

Post-procedure care following the monitoring of intraocular pressure involves providing the patient with information regarding the results of the monitoring. The physician will discuss the findings and any necessary follow-up actions, which may include further testing or adjustments to the treatment plan based on the intraocular pressure readings. Patients may also be advised on any symptoms to monitor and when to seek further medical attention. It is important for patients to attend follow-up appointments to ensure ongoing management of their ocular health.
