Retinal detachment repair is one of the more commonly performed procedures in ophthalmic billing. Despite its high demand, ophthalmology practices can often make billing errors because of the complexity of the codes.
CPT code 67108 specifically covers repair performed with a pars plana vitrectomy, but that’s not all. Understanding what the code includes and excludes is essential for accurate coding and claim submission. So, let’s discuss the following:
- Code’s description
- Clinical situations where it applies
- Commonly appended modifiers
- Reimbursement rules governing submission
CPT Code 67108 – Description
67108 falls under the ‘Repair Procedures on the Retina or Choroid’ subsection of the CPT coding manual maintained by the American Medical Association (AMA). According to the official description, CPT code 67108 is fundamentally a surgical procedure code and covers the repair of a retinal detachment using vitrectomy.
It bundles multiple adjunct steps performed within the same operative session. The steps that may be bundled include the following:
- Focal endolaser photocoagulation
- Scleral buckling
- Air or gas tamponade
- Cryotherapy
- Drainage of subretinal fluid
- Lens removal, performed during the same operative session, when appropriate
Understanding CPT 67108
Bundling rules for CPT code 67108 are a common source of coding errors and claim denials. Since 67108 covers adjunct techniques, medical billers should not report them as separate line items. However, this applies if the techniques are performed within the same session as the vitrectomy.
Newer billers may be tempted to itemize each surgical step rather than understanding that the primary CPT code covers the complete scope of the procedure.
Choosing an appropriate code relies heavily on the diagnosis. For example, a vitrectomy may be performed for a:
- Vitreous hemorrhage
- Macular hole
- Retinal detachment
But each of these diagnoses requires a different CPT code. Although the surgical technique may be similar, the appropriate CPT code selection depends on the underlying diagnosis, according to Retina Today. Thus, coders should review the documented diagnosis before selecting the final code.
Scenarios Where CPT Code 67108 is Applicable
Since CPT code 67108 bundles several procedures performed during the same operative session, knowing when and how to bill it correctly can be challenging. Therefore, to ease this confusion, let’s discuss clinical scenarios where 67108 applies:
Vitrectomy with Gas Tamponade
Consider the case of a 67-year-old male who is treated by a vitreoretinal specialist in a hospital outpatient department for primary rhegmatogenous retinal detachment. The surgeon performs:
- Endolaser photocoagulation
- Pars plana vitrectomy with fluid-air exchange
- Intraocular gas tamponade to reattach the retina
Here, gas tamponade is a crucial part of the retinal detachment repair performed during the same operative session. Thus, it is not billed separately, and CPT code 67108 is used to submit the claim.
Vitrectomy with Scleral Buckling for Multiple Retinal Breaks
Consider the case of a 59-year-old female who is diagnosed with a primary rhegmatogenous retinal detachment involving multiple retinal breaks. The patient undergoes surgery in a hospital setting, performed by a vitreoretinal specialist.
During the procedure, the surgeon performs:
- Pars plana vitrectomy
- Scleral buckling
- Fluid-air exchange
- Endolaser photocoagulation
- Intraocular gas tamponade
Since the scleral buckle and other adjunct procedures are considered a part of the retinal detachment repair during the same operative session, they are not reported separately. The billing team uses CPT code 67108 to bill the payer.
Vitrectomy with Endolaser and Subretinal Fluid Drainage
Imagine the case of a 73-year-old male who arrives at an ambulatory surgery center for primary rhegmatogenous retinal detachment. The vitreoretinal specialist performs:
- Pars plana vitrectomy with drainage of subretinal fluid
- Endolaser photocoagulation
- Gas-fluid exchange
Therefore, the claim is correctly submitted under CPT code 67108.
Applicable Modifiers for CPT Code 67108
The following modifiers may be most commonly reported with this code.
| Modifier | What It Indicates |
|---|---|
| RT | The retinal repair was performed on the right eye only. |
| LT | The retinal repair was performed on the left eye only. |
| 50 | The retinal repair was performed on both eyes in the same operative session. |
| 58 | The repair was a staged or related procedure performed within the postoperative period of a prior surgery. |
| 78 | The repair was unplanned and resulted in a return to the operating room within the global period of another surgery. |
| 79 | The repair was an unrelated procedure performed by the same physician during the postoperative period of another surgery. |
Important Billing Note: Modifier(s) should always be selected when supported by clear documentation.
CPT Code 67108 – Billing & Reimbursement Guidelines
For Medicare-enrolled providers and patients, reimbursement for CPT 67108 depends on the Medicare Physician Fee Schedule (MPFS). But the actual payment may vary based on the:
- Geographic locality
- Service setting (facility or non-facility)
- Medicare Administrative Contractor (MAC) payer contract terms
Generally, the following reimbursement guidelines may apply to 67108:
Bundling Rules
According to the CMS guide, several procedures may be bundled within 67108. Thus, applicable procedures should not be reported separately if performed during the same operative session as the retinal detachment repair.
Likewise, lens removal performed as an integral part of the same procedure is generally included in CPT code 67108 and is not separately reported.
Medical Necessity
CPT code 67108 should be reported only when the retinal detachment repair is medically necessary and supported by appropriate documentation. Insufficient documentation may result in claim rejection, denial, payment delays, or audit risk.
Payer-Specific Policies
Payer-specific policies can alter the billing rules for a 67108 claim as they vary across insurance carriers and plans. Therefore, the billing staff should always review the latest policies before billing for this CPT code.
Correct Modifier Use
As mentioned earlier, one or more modifiers may apply to a 67108 claim, depending on the specific scenario. Therefore, the billing team must append the accurate modifier, supported by documentation.
Wrapping It Up
CPT code 67108 is the appropriate CPT code for retinal detachment repair involving vitrectomy. Its description bundles adjunct techniques such as tamponade, photocoagulation, and scleral buckling.
However, accurate billing depends on confirming the diagnosis, understanding bundled services, applying modifiers appropriately, and maintaining comprehensive documentation.
