Why Modifiers Play a Crucial Role In Reimbursement

Modifiers- what are they and why do we need them? Well, in short, we need them to get paid correctly. Appropriately placed modifiers can mean the difference between a large payment or a little payment or even a payment at all!

Insurance carriers use modifiers to decide various things including:

  • Which eye the procedure/testing was performed on or if it was performed on both
  • If a certain procedure is included or separate and distinct from another
  • If multiple procedures were performed on the same day
  • If the provider recognizes the procedure as one in which Medicare doesn’t allow payment

All the indicators above are financially impacting to a practice. For example, if a procedure was performed bilaterally, but is typically unilateral in nature, then not using a modifier to indicate it was performed bilaterally can result in a reduction in payment. Additionally, even if the payer does submit payment, an audit could take it back later.

Below are some of the most frequently used modifiers as well as their description.

RT/LT – Right side or left side

GY –Provider is aware the service is excluded by Medicare

25 –When a patient has an office visit that is separate from a procedure performed on the same day. The intention is to unbundle the codes; however, the decision to do so depends on the payer and diagnosis.

50 – Bilateral procedure; used when a procedure is performed on both eyes, but the code is unilateral in nature

51 – Used when multiple procedures for the same patient are performed on the same day. Don’t forget to bill the highest paying procedures first so that the multiple procedure discount is taken from the smaller of the payments.

52 – Reduced services; Used when a procedure is only performed on a single eye, but the code is bilateral in nature

55 –Used with post-op cataract claims. It indicates that co-management is taking place with the surgeon.

Keep in mind that it is important to only use modifiers that indicate what truly took place. Using modifiers to simply increase reimbursement is illegal and that sort of audit could be devastating to a practice.

In addition to those above, there are several other modifiers that are pertinent to the optometric space. Familiarizing yourself can definitely help decrease denials and increase reimbursement.
