Article Guidance

Article Text

This Billing and Coding Article provides billing and coding guidance for Local Coverage Determination (LCD) L38223, Micro-Invasive Glaucoma Surgery (MIGS). Please refer to the LCD for reasonable and necessary requirements.

Coding Guidance

Notice: It is not appropriate to bill Medicare for services that are not covered (as described by the entire LCD) as if they are covered. When billing for non-covered services, use the appropriate modifier.

Utilization Parameters

Medicare may cover only 1 unit per eye, per date of service of CPT code 66989 or 66991 for insertion of glaucoma drainage device(s) into the trabecular meshwork (e.g., iStent^®, or iStent inject^®), performed in conjunction with cataract surgery and when the medically reasonable and necessary criteria as stated in the LCD are met. Although more than one drainage device into the trabecular meshwork of a single eye on a single day of service, may be performed using an insertion tool loaded with more than one device, (e.g., iStent inject^®), once the insertion tool is deployed within the eye, the work and clinical skill required to place additional device(s) is equivalent to placement of other U.S. Food and Drug Administration (FDA) cleared devices described by the same codes. Therefore, only one unit of 66989 or 66991 per eye per day may be billed, regardless of the number of devices inserted into a single eye on the same date of service.

Medicare may cover only 1 unit per eye, per date of service of CPT code 0449T for insertion of glaucoma drainage device(s) into the subconjunctival space (e.g., XEN45^®), when the medically reasonable and necessary criteria as stated in the LCD are met.

Note: CPT Code 0450T for additional device insertion is not covered.

Note: CPT code 0671T does not need to be reported with any of the following codes: 66982, 66983, 66984, 66987, and 66988.

Documentation Requirements

All documentation must be maintained in the patient's medical record and must support the medical necessity of the services as directed in this article and be made available to the contractor upon request.
Every page of the record must be legible and include appropriate patient identification information (e.g., complete name, dates of service[s]). The documentation must include the legible signature of the physician or non-physician practitioner responsible for and providing the care to the patient.
The submitted medical record must support the use of the selected ICD-10-CM code(s). The submitted CPT/HCPCS code must describe the service performed.
