By Stephanie Adams Ophthalmology Coding
The 57 modifier in ophthalmology is a billing code used to indicate that the decision for major surgery was made during an evaluation and management (E/M) service, typically on the same day or the day before the surgery. It ensures that the payer recognizes the E/M visit as medically necessary and separately billable from the surgical procedure itself.
Purpose and Usage of the 57 Modifier
- Major Surgery Definition: “Major” refers to any surgical procedure with a 90-day post-operative global period, as determined by Medicare and most insurers. Common ophthalmic major surgeries include retinal detachments, some laser procedures, or globe repairs.
- When to Apply: Use the 57 modifier on the E/M service when the decision for surgery occurs on the day of or day before the procedure. This tells payers that the exam led directly to the surgical decision and qualifies for separate reimbursement.
- Proper Billing Example: If a patient visits with acute symptom – such as flashes and floater – and is diagnosed with a retinal tear requiring immediate laser surgery, appending the 57 modifier to the exam (E/M visit) code signals that the decision for major surgery was made at that encounter.
Key Points and Examples
- Not for Minor Surgeries: Do not use the 57 modifier for minor surgeries (those with a 0- or 10-day global period); for those, use the 25 modifier if appropriate.
- Timing Matters: If the decision for surgery was made at a prior visit, do not use modifier 57 on a preoperative exam performed on the day before or the day of surgery – the global period rules mean the E/M is considered part of the global package and not separately payable.
- Ophthalmology Example: For a ruptured globe repair performed on the day of diagnosis, modifier 57 should be appended to the E/M code to guarantee payment for the examination in addition to the surgical procedure. Conversely, if the provider decides at a routine visit to schedule a cataract surgery in the future (not the same or following day), modifier 57 does not apply.
How Modifier 57 Impacts Payment
- Correct usage prevents the payer from “bundling” the E/M visit with the surgical procedure, ensuring both are covered – this is particularly important when urgent surgical decisions are made during an ophthalmic evaluation.
- Incorrect application (for minor surgeries or unrelated diagnoses) can result in claim rejections or delayed payments.
Quick Comparison Table
| Modifier | When Used | Type of Surgery | Global Period | Purpose |
| 57 | E/M visit leads to decision for surgery | Major (e.g., retina, globe repair) | 90 days | Signals E/M visit led to major surgery decision |
| 25 | E/M visit with separately identifiable service on day of minor surgery | Minor (e.g., injection, iridotomy) | 0 or 10 days | E/M service significant, distinct from minor surgery |
Important Takeaways
- Modifier 57 is essential whenever an E/M service results in the decision to perform a major ophthalmic surgery immediately or within one day.
- Documentation should clearly reflect that the decision for surgery was made during the E/M visit.
- Proper use of the 57 modifier helps secure legitimate reimbursement for both the evaluation and the surgical procedure in urgent eye care scenarios.
