Vitreoretinal surgery is one of the most heavily scrutinized areas in ophthalmology billing. At the center of it is CPT code 67036. This is the base code for all vitrectomy procedures. However, billing it can be quite complex.
That’s why our billing experts at MediBillMD have created this detailed guide on this code. We will explain what 67036 is and how you can use it effectively in your claims. So, let’s start.
CPT Code 67036 – Description
CPT code 67036 is defined as:
“Vitrectomy, mechanical, pars plana approach.”
67036 is the base code in the ‘Vitreous Procedures on the Posterior Segment of the Eye’ code range, from 67036 through 67043. As evident from the definition, 67036 is used for a pars plana vitrectomy (PPV). It is a surgical procedure in which the physician removes the vitreous gel from the eye. This is done to access the posterior segment of the eye.
67036 is used when only the vitrectomy is performed. Whereas, other codes in the family are used when vitrectomy is combined with other additional services like endolaser photocoagulation or membrane removal. When a PPV is performed without any of these additional services, 67036 is the right code to report.
Scenarios Where CPT Code 67036 is Applicable
Let’s look at a couple of real-world scenarios in which CPT code 67036 applies:
Scenario 1
Let’s suppose that a patient comes to an eye clinic. He has a history of diabetic retinopathy. However, this visit is not for retinopathy. The patient has a significant drop in vision, so he decides to get his eyes checked.
The physician performs a dilated fundus examination. The tests show that the retina is obscured by dense vitreous hemorrhage. The physician performs another test (B-scan ultrasonography) to make sure that the retina is not detached. The test rules out retinal detachment. So, the surgeon proceeds with a pars plana vitrectomy to clear the hemorrhage and restore a visual axis.
Now, since the purpose of the surgery was to remove the hemorrhage and not repair the retina, the billing department can use CPT code 67036 to bill the vitrectomy.
Scenario 2
One example might not be enough to clear the concept, so let’s look at another scenario. Suppose that a 58-year-old patient presents with a longstanding history of vitreous floaters that have progressively worsened over the past year. The patient describes persistent, large, mobile shadows and strands drifting across the visual field, which are especially bothersome when looking at bright backgrounds like a white wall, a computer screen, or the sky. The symptoms have significantly interfered with reading, driving, and daily activities, and the patient reports considerable frustration and reduced quality of life.
On examination, best-corrected visual acuity is largely preserved, but dilated fundus exam and slit-lamp evaluation with a fundus contact lens confirm dense, prominent vitreous opacities consistent with age-related vitreous syneresis (degeneration) rather than hemorrhage, inflammation, or retinal pathology. B-scan ultrasound and OCT are performed to rule out retinal tears, detachment, or other posterior segment disease. No other ocular pathology is found.
Conservative options are discussed, including observation and YAG laser vitreolysis, but the patient’s symptoms are severe enough, and other treatments seem insufficient. Hence, the ophthalmologist decides on surgical intervention.
He performs a pars plana vitrectomy, mechanically removing the vitreous gel along with the floaters/opacities suspended within it. The core vitreous is removed, with attention to clearing the visual axis while avoiding traction on the retina. No lens extraction, membrane peeling, retinal repair, or tamponade (gas/oil) is performed. Therefore, the billing team can report CPT code 67036 for reimbursement.
Applicable Modifiers for CPT Code 67036
The following modifiers are frequently used with CPT code 67036:
| Modifier | Description | Application |
|---|---|---|
| LT | Left Side Procedure | Use when the vitrectomy is performed on the left eye. |
| RT | Right Side Procedure | Use this when the vitrectomy is performed on the right eye. |
| 58 | Staged or Related Procedure | It is used when the vitrectomy is a planned, staged procedure performed during the postoperative period of a prior related surgery. |
| 78 | Unplanned Return to the Operating Room | Use when the patient must unexpectedly return to the operating room. |
| 79 | Unrelated Procedure During Postoperative Period | Use when the vitrectomy is unrelated to a prior surgery performed on the same patient within the global period, such as a procedure on the fellow eye. |
Note: Modifiers 58,78,79 should only be used with 67036 when 67036 is used within the 90-day global period of another major surgical procedure.
CPT Code 67036 – Billing & Reimbursement Guidelines
Understanding the code and using modifiers isn’t enough to get your claims reimbursed. Here are some guidelines about CPT code 67036 that are essential to follow:
Watch for NCCI Bundling Edits
CPT code 67036 is bundled with several related codes under the National Correct Coding Initiative (NCCI). For example, CPT code 67121 (removal of implanted material, posterior segment) is bundled with 67036 and generally cannot be billed separately.
Similarly, CPT code 67145 is bundled with 67036, so the two codes cannot be reported separately for the same service date.
Provide Detailed Documentation
As with all surgical CPT codes, thorough documentation is what separates a paid claim from a denied one. Your operative report should clearly include:
- Reason: The specific diagnosis and covered ICD-10 code.
- Technique: Confirmation that a mechanical, pars plana approach was used.
- Findings: A description of what was found and removed, such as hemorrhage, retained fragments, or vitreous opacities.
- Additional maneuvers: Explicit notation of whether laser, membrane removal, or tamponade was or was not performed, since this determines whether 67036 or a related code applies.
- Laterality: Clear documentation of which eye was treated to support the RT or LT modifier.
Wrapping Up
This is it! We have reached the end of our guide. Hopefully, it will help you improve your claim acceptance rate. If you missed any of the essential points discussed above, here’s a quick recap of the most important ones:
- CPT code 67036 is an ophthalmology billing code and is used to bill a pars plana vitrectomy.
- CPT codes 67121 and 67145 are bundled with 67036.
- Always append appropriate modifiers with the claim when necessary.
- Provide detailed documentation with every 67036 claim.
Claim denials on high-value surgical codes like 67036 can add up quickly and lead to significant revenue loss. If billing is frustrating for you, our ophthalmology billing services are built to handle the coding complexity and prevent denials.
