This is a percentage-based premium of 25% that is added to the fee for E132 (Glaucoma filtering procedures). This premium is applicable when the current glaucoma filtering procedure is performed following a previous glaucoma filtering procedure on the same eye.

When to Use

Use E983 when performing a repeat trabeculectomy (E132) on an eye that has previously undergone a glaucoma filtering procedure.
Apply this code when performing a revision or secondary filtering procedure on an eye where the initial E132 procedure failed to maintain adequate intraocular pressure control.

Common Pitfalls

Billing E983 without a corresponding E132 claim, as E983 is a percentage-based premium that requires the base procedure to be present on the same claim.
Applying E983 to procedures that are not classified under E132, such as valve implants or other non-filtering glaucoma surgeries.
Failing to document the history of the previous filtering procedure in the patient record, which is essential for audit justification of the 25% premium.

Billing Tips

Ensure E983 is submitted on the same claim as E132 to trigger the 25% increase on the base fee automatically.
If the procedure is performed on both eyes, ensure the previous surgery history is clearly documented for each eye individually to support the premium for each side.
