Medicare patient. Admitted with a 99223 and 5 hours later requires critical care which includes an arterial line. What is the proper modifier usage?

modifier 25

re: Modifier 25 usage

If a patient is admitted 99223 and later goes critical you can also bill the critical care code 99291 as well as the art line 36620. You would use the 25 on both 99223 and 99291. Your notes should be very clear and support the admission and later going critical.

Thank you for the replies. Here is another one.
Medicare patient is admitted with a 99223 and later in the day requires critical care with 99291 and 99292.
How is the 25 modifier used in this instance?
Thank you.

re: Modifier 25 usage

99223-25
99291-25
99292-25
Is how we submit our cases like that.

Thank you for your reply. Can you tell me why you have a 25 on the 99223?
