Question:
We are submitting a hospital claim form with the modifier 25 and FS modifier. We are unsure which modifier to list first. What is your recommendation?

Answer:
Thanks for contacting KZA and remembering to use the FS modifier for shared services provided in the hospital. KZA recommends placing the modifier 25 first, as this is considered a reimbursement modifier followed by the FS modifier, which is an informational modifier.
