What does the modifier -52 indicate?

The modifier -52 is used to indicate that a service or procedure was reduced in complexity or that it was only partially completed. When a procedure is performed but not to its full extent or the entire service is not necessary due to specific circumstances, modifier -52 helps communicate this to payers. It signifies that the provider is billing for a lesser service than typically expected for that procedure, which can often occur due to patient factors, clinical judgment, or specific situational variables that limit the extent of services provided. Understanding the appropriate use of this modifier is important for accurate coding and billing, ensuring that healthcare providers are appropriately reimbursed for the services they deliver.
