We are attempting to bill post-op care for a cataract/iStent insertion using a 55 modifier. Medicare has denied our submission of 0191T-55.
Can the 55 modifier ONLY be used with the actual cataract code, 66984?

Any input is appreciated!

0191T does not have a global period assigned you would want to use the primary surgical code.
