A modifier explanation on page 61 of the 2019 CPT code book says:

Anesthesia Modifiers

All "anesthesia services" are reported by use of the anesthesia five-digit procedure code (00100-01999) plus the addition of a physical status modifier. The use of other optional modifiers may be appropriate.

To me this direction clearly indicates that anesthesia services are reported using codes 00100-01999 and although other services are rendered by a provider in our anesthesia unit it does not make them anesthesia codes nor do we need to place a modifier to show who did it. For instance if one of the anesthesiologists and/or a CRNA provided an epidural, blood patch a modifier of AA or QZ is not needed simply placing the provider who rendered the service in the proper field for the non-anesthesia codes should suffice.

is this not correct? i did a little google research and some of the Blue Cross’s clearly indicate that the anesthesia modifiers are to only be placed on anesthesia codes i cannot seem to find a link to an actual resource of say CMS, AAPC that has those exact words in it ….

opinions, thoughts?
