Which modifier should be used when a provider offers only the postoperative aspect of care?

The appropriate modifier to indicate that a provider is offering only the postoperative aspect of care is Modifier 55. This modifier is specifically used to identify a situation where one provider has performed the surgical procedure, while another provider is responsible for the postoperative care. When Modifier 55 is attached to the appropriate CPT code, it highlights that the care provided is limited to the postoperative period, ensuring clear communication and accurate billing for each provider's services.

In situations concerning the other modifiers, Modifier 54 refers to the surgical care only, suggesting that the provider is billing for just the procedure without any postoperative or preoperative aspects. Modifier 56 indicates that the provider is only responsible for preoperative care, which does not apply here since the question specifies postoperative care. Modifier 52, used for reduced services, does not accurately describe the scenario where postoperative care alone is being provided, as it does not denote the specific context of postoperative responsibility. Therefore, the application of Modifier 55 effectively distinguishes the scope of care being billed.
