Recognize the Right Retinal Detachment Repair Code
Watch out for bundled services and related errors. The retina is a thin layer of tissue in the back of the eye that captures light and sends images to the brain. When it detaches due to aging, injury, or a medical condition, the detachment can lead to permanent vision loss. When a surgeon performs a retinal detachment repair, the procedure may involve pneumatic retinopexy, scleral buckling, or vitrectomy. But even when a surgeon uses several techniques during a single repair, coders should not assume that each technique has its own CPT® code. Instead, coders should identify the primary retinal detachment repair technique, determine whether the detachment is complex or recurrent, and understand which component procedures the selected code already includes. Start With the Operative Approach The 67101 (Repair of retinal detachment, including drainage of subretinal fluid when performed; cryotherapy) through 67121 (Removal of implanted material, posterior segment; intraocular) CPT® code range covers procedures on the retina or choroid. Specifically, the following codes apply to retinal detachment procedures: Do not select a code because one word, such as “laser” or “gas,” appears in the operative note. Instead, determine what technique the surgeon used to repair the detachment, and which code descriptor encompasses the whole procedure. Pneumatic retinopexy involves injecting a gas bubble into the eye; the bubble presses against the retinal break and helps seal it. The surgeon may also use cryotherapy or laser treatment to seal the area around the break. When the documentation supports pneumatic retinopexy without a vitrectomy, select 67110 to report the procedure. For example, an operative note might describe identification of a superior retinal tear, cryotherapy around the tear, and injection of an expansile gas bubble. If the surgeon did not perform a vitrectomy or scleral buckle, look to 67110 rather than reporting the gas injection and retinal treatment separately. This distinction becomes especially important when the surgeon documents multiple steps during the repair. Documentation of cryotherapy or photocoagulation does not automatically create an additional separately reportable retinal procedure. Scleral buckling repairs the detachment through an external approach. The surgeon places a silicone band or other buckling material around the outside of the eye, creating an indentation that supports the retinal break. The surgeon may also perform cryotherapy and drainage of subretinal fluid. For a retinal detachment repaired with scleral buckling, select 67107 if the documentation does not meet the criteria for a different retinal detachment repair code. Avoid coding the buckle as one procedure and then separately reporting the cryotherapy, drainage of subretinal fluid, or other work that is already included in 67107. Review the operative report to determine the actual repair technique rather than counting every individual surgical step. If the surgeon performs a vitrectomy to repair the retinal detachment, consider 67108, which encompasses vitrectomy with or without air or gas tamponade and may include focal endolaser photocoagulation, cryotherapy, subretinal fluid drainage, scleral buckling, and removal of a lens by the same technique. Know When to Consider Complex Repair or Recurrent Repairs Review the documentation for evidence that the retinal detachment meets the requirements for complex retinal detachment repair. Look for documentation of the detachment’s complexity and whether the surgeon performed vitrectomy and membrane peeling. If the procedure meets the definition of a complex retinal detachment, apply 67113. This code encompasses associated procedures such as air, gas or silicone oil tamponade, cryotherapy, endolaser photocoagulation, subretinal fluid drainage, scleral buckling, and lens removal by the same technique. Further, consider whether the patient previously underwent retinal detachment repair in the same eye. When reporting a repeat retinal detachment repair, select the CPT® code based on the technique and complexity that the physician documents for the current procedure rather than the patient’s history of prior repair. For example, a coder may select 67107 for repeat repair with scleral buckling, while a repeat repair with vitrectomy may support 67108. If the documentation indicates a complex retinal detachment with vitrectomy and membrane peeling, 67113 may apply. Review the operative report and current CPT® guidelines to determine which code accurately describes the current repair. Link the Procedure to the Diagnosis The CPT® code and the diagnosis code answer different questions, but they must be consistent. Start by identifying the type of retinal detachment the physician documented. The documentation should create a clear link between the diagnosis and procedure: The diagnosis explains why the surgeon performed the repair, and the operative report explains how the surgeon performed it. For example, a rhegmatogenous retinal detachment happens when a tear or hole lets fluid build up under the retina; while a tractional retinal detachment develops when scar tissue pulls the retina away from the back of the eye, which can occur with conditions like diabetic retinopathy. The documented diagnosis can affect the appropriate repair code. Next, check laterality. The operative report should identify the same eye listed on the claim. Coders should also distinguish a retinal tear or break from a retinal detachment. Keep in mind that a retinal tear by itself does not equate to a retinal detachment. Let’s refer back to the tractional retinal detachment example. In this case, assume the patient has type 2 diabetes with proliferative diabetic retinopathy and a tractional retinal detachment in the right eye that does not involve the macula. If the surgeon performs a vitrectomy with membrane peeling to repair the detachment, the correct codes are 67113 for the complex retinal detachment repair and E11.3531 (Type 2 diabetes mellitus with proliferative diabetic retinopathy with traction retinal detachment not involving the macula, right eye). Watch out for Bundled Services Bundling errors occur when coders report retinal detachment repair procedures separately even though the primary CPT® code already includes the documented work. Retinal detachment repair codes are mutually exclusive when the surgeon performs the procedure on the same eye on the same date of service. Keep in mind that 67108 includes several vitreous procedures. For example, when a surgeon performs a vitrectomy with gas tamponade to repair a retinal detachment, the coder should report the appropriate retinal detachment repair code based on the operative documentation rather than automatically reporting both 67108 and 67110. Code 67108 already includes the work associated with gas tamponade. The same principle applies when the surgeon performs a scleral buckle as part of a vitrectomy-based retinal detachment repair: Do not automatically report both 67107 and 67108 because the descriptor for 67108 includes scleral buckling. Coders should apply this same logic to other services included in a retinal detachment repair code. First, identify the procedure the surgeon performed and select the code that accurately describes the primary service. Then, review the code descriptor and determine whether the code already includes the additional documented services. Report a separate CPT® code only when the documentation supports a separately reportable service. Michelle Falci, BA, M Falci Communications LLC
