HCPCS Codes

The following HCPCS codes may be appropriate for reporting when iStent infinite is used, and the number of service units for the code reported may correspond to the number of stents deployed.

HCPCS Code Description Revenue Code
C1783 Ocular implant; aqueous drainage assist device 0278; other implants
L8612 Aqueous shunt 0278; other implants

Diagnosis Codes

The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) is the coding system used to report patient diagnoses. Diagnosis codes are used to document the indication for the procedure and may include additional diagnoses of other clinical conditions applicable to a healthcare visit. It is up to the provider to determine the appropriate diagnosis code(s) on the claim.

  • H40.XXXX – Glaucoma

Claims Submission Process

Each provider is responsible for ensuring all claims are accurately coded and submitted on a timely basis. Fully documented claims helps to minimize delay in proper reimbursement.

Other Coverage Information


Private payers may require a prior authorization before performing the iStent infinite® procedure.

Please check with your local Glaukos Regional Business Manager or Field Reimbursement Director for the latest updates on coverage in your area. Your Glaukos reimbursement team can be reached at marketaccess@glaukos.com

2024 National Average Unadjusted Medicare Payment

Private payers each employ their own methodology to determine payment amounts for services based on the CPT, ICD-10 and HCPCS codes billed on the claim and payment will be contingent upon the contractual agreement.

Facility billing departments should check the service contracts with individual private payers or contact each payer directly to verify the applicable reimbursement methodologies and/or amounts for the iStent infinite® implantation. All HOPDs must include the iStent infinite® device on their claim forms to payers in order to capture the full cost of providing the service.

Medicare will package the device reimbursement with the surgical facility payment for 0671T, some commercial payer claims in the Ambulatory Surgery Center setting may pay a carve-out for the iStent infinite® implant. A review of the specific payer’s requirement is recommended.

iStent infinite® Important Safety Information

Indication for Use

The iStent infinite® Trabecular Micro-Bypass System Model iS3 is an implantable device intended to reduce the intraocular pressure (IOP) of the eye. It is indicated for use in adult patients with primary open-angle glaucoma in whom previous medical and surgical treatment has failed.

Contraindications

The iStent infinite is contraindicated in eyes with angle-closure glaucoma where the angle has not been surgically opened, acute traumatic, malignant, active uveitic, or active neovascular glaucoma, discernible congenital anomalies of the anterior chamber (AC) angle, retrobulbar tumor, thyroid eye disease, or Sturge-Weber Syndrome or any other type of condition that may cause elevated episcleral venous pressure.

Warnings

Gonioscopy should be performed prior to surgery to exclude congenital anomalies of the angle, PAS, rubeosis, or conditions that would prohibit adequate visualization that could lead to improper placement of the stent and pose a hazard.

MRI Information

The iStent infinite is MR-Conditional, i.e., the device is safe for use in a specified MR environment under specified conditions; please see Directions for Use (DFU) label for details.

Precautions

The surgeon should monitor the patient postoperatively for proper maintenance of IOP. Three out of 61 participants (4.9%) in the pivotal clinical trial were phakic. Therefore, there is insufficient evidence to determine whether the clinical performance of the device may be different in those who are phakic versus in those who are pseudophakic.

Adverse Events

The most common postoperative adverse events reported in the iStent infinite pivotal trial included IOP increase ≥ 10 mmHg vs. baseline IOP (8.2%), loss of BSCVA ≥ 2 lines (11.5%), ocular surface disease (11.5%), perioperative inflammation (6.6%) and visual field loss ≥ 2.5 dB (6.6%).

Caution

Federal law restricts this device to sale by, or on the order of, a physician. Please see DFU for a complete list of contraindications, warnings, precautions, and adverse events.
