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?
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.
