Retina clinics provide intravitreal injections each and every day and the CPT 67028 code covers the injection procedure. The medication is generally reported separately using the applicable HCPCS Level II code and the correct number of billing units. Also, here the claim requires a modifier showing which eye is treated and the visit needs proper documentation supporting the service performed, drug administered, diagnosis, dosage and treated eye.
CMS ties the injection code to the drug code closely enough that a denial of one component may also affect reimbursement for the associated claim component. Get the procedure code wrong or leave out the required eye modifier and a practice can lose payment for a drug that costs thousands of dollars per dose. This is why many clinics turn to outsourced retina medical billing companies for specialized billing support.
What Is CPT 67028?
CPT 67028 reports the intravitreal injection of a pharmacologic agent into the vitreous cavity. It does not cover the drug itself, which is a distinction that trips newer coders more often than you’d expect. CMS billing guidance identifies CPT 67028 for administration of several ophthalmic drugs, which are reported separately using the applicable HCPCS codes.
A typical retina medical billing claim has two connected pieces. There’s the physician’s work, billed as 67028 and there’s the drug, billed under its own HCPCS code. Although they are reported on separate claim lines, payers may evaluate the drug and its administration together for medical necessity and coding consistency.
None of these makes 67028 a code for any injection near the eye. The procedure performed, the drug used, the eye treated, the diagnosis on file and the specific payer’s rules all must match the claim and a mismatch anywhere in that chain is usually where trouble starts.
When Should CPT 67028 Be Billed?
CMS coverage and coding articles name this code specifically for administering several ophthalmic drugs. Below are some several factors need to be considered when billing this CPT code, including:
1) Drug and Injection Billing
Where practices run into trouble is separating the drug from the injection on the claim. For Medicare and other payers that separately reimburse the drug and administration, the drug and injection are reported as distinct claim lines.
2) Laterality Requirements
Laterality matters more than it might seem. CMS coding guidance calls for RT, LT, or modifier 50 on 67028 depending on whether one eye or both eyes got the injection. While for this issue some Medicare contractors might even reject a claim outright if that modifier is missing. It’s a small detail that causes a disproportionate number of denials.
3) Medical Necessity and Utilization
Medical necessity is another important consideration because the patient’s diagnosis and treatment pattern need to align with applicable coverage requirements. Dosing and frequency should be consistent with applicable coverage requirements and where relevant FDA-approved labeling. The outsourced retina medical billing company knows that claims that exceed applicable utilization parameters may be subject to additional medical necessity review.
Common CPT 67028 Mistakes in Retina Medical Billing
The smallest billing mistakes can lead to claim denials, delayed reimbursement and compliance issues for retina clinics. One of the most common issues is incorrect modifiers usage, missing information, documentation gaps, and failure to follow all the payer’s specific billing needs.
1) Billing the Drug as Part of CPT 67028
The most basic mistake is billing 67028 as though it already includes the medication. It doesn’t and CMS assigns drugs like aflibercept their own HCPCS codes for a reason, billed alongside the administration service rather than folded into it.
2) Laterality Errors
Laterality mistakes come next and they’re avoidable ones. The wrong eye on the claim or no eye modifier at all causes denials fast. CMS wants RT, LT, or 50 depending on whether the injection covers one eye or both, and this is one of the easier things to catch in a pre-submission review while creating the right retina medical billing services.
3) Drug Waste Reporting Errors
Drug waste rules get ignored more often than they should. Failing to report discarded amounts on single-dose containers, or skipping JZ when nothing was wasted, creates a compliance problem and a payment problem at the same time. CMS uses JW for discarded amounts and JZ to confirm nothing was discarded, and the two are not interchangeable.
4) Outdated Drug Codes
Outdated drug coding rounds out the list. New anti-VEGF products and biosimilars can receive new or specific HCPCS coding, making it important to verify current coding guidance. A billing sheet from even a year ago can already be missing a code a practice needs today.
How to Bill CPT 67028 With the Injected Drug
Billing CPT 67028 correctly involves reporting the injection procedure, the applicable drug, and any required drug wastage information. These are described below:
1) Report the Injection Procedure
Start with the injection itself, since accurate procedure coding is a critical part of retina medical billing services. 67028 covers the clinician’s work of administering the drug, and CMS instructs providers to report it on the same claim as the matching medication for several retinal therapies.
2) Match Procedure, Drug, Diagnosis, Units, and Laterality
The procedure, drug, diagnosis, units, and laterality all need to agree with each other. A drug claim denied for medical necessity may also affect reimbursement for the associated administration service, depending on the payer’s policy.
3) Report Discarded Drug Correctly
Discarded drug gets its own step. When a single-dose container has leftover medication that gets thrown away, that amount goes on the claim as JW. When nothing gets discarded, JZ goes on instead. Both modifiers apply specifically to separately payable drugs and biologicals under the policy, not to every medication or supply that shows up on the claim.
CPT 67028 Modifiers: Which Modifiers Matter in Retina Medical Billing?
Modifiers add specific context to a procedure code without changing the very core definition. These modifiers provide important information that can help support accurate claim submission.
1) RT and LT Modifiers
RT marks the right eye and LT marks the left. CMS billing guidance for intravitreal drugs directs providers to add the correct site modifier to 67028 whenever the payer calls for it, which is most of the time.
2) Modifier 50
CMS ophthalmology guidance names modifier 50 for bilateral 67028 claims in the right circumstances, though payer rules vary enough here that it’s worth confirming with the specific Medicare contractor or commercial payer before submitting.
3) Modifier 25
Modifier 25 goes with the E/M code and never with 67028 itself. The AMA defines it as a significant, separately identifiable E/M service performed by the same clinician on the same day as another procedure. CMS has paid closer attention to this pairing since the OIG audit, so 25 should never end up on a claim out of habit. The record must show an E/M service that goes beyond the routine work of giving the injection, or it doesn’t belong there.
4) JW and JZ Modifiers
JW and JZ report discarded or non-discarded drug amounts, and they live on the drug billing side of the claim rather than functioning as modifiers for the injection code.
Managing these requirements alongside patient care can place a significant administrative burden on retina practices. This is where specialized third-party billing support can help.
