Update to 2018 ASA CROSSWALK® Entries for Procedure Codes 45330 and 45378

The 2018 CPT^® code set includes five new codes specific to anesthesia care for GI endoscopy. These five new codes replace two codes that were deleted from CPT and cannot be used to report care provided on/after January 1, 2018.

In this Timely Topic, we provide additional information specific to the 2018 CROSSWALK entries for procedure codes 45330 - Sigmoidoscopy, flexible; diagnostic, including collection of specimen(s) by brushing or washing, when performed (separate procedure) and 45378 - Colonoscopy, flexible; diagnostic, including collection of specimen(s) by brushing or washing, when performed (separate procedure).

The 2018 CROSSWALK entries for these procedures list code 00812 as the primary anesthesia code option and offer code 00813 as an alternative to be reported when the patient undergoes both an upper and lower GI endoscopy during the same anesthetic.

The ASA CROSSWALK Editorial Panel notes that in some instances, it may be appropriate to report anesthesia care for these procedures with code 00811, such as when a screening colonoscopy becomes a diagnostic colonoscopy. The Centers for Medicare & Medicaid Services (CMS) has posted instructions that support this stance via MM10181 and R3844CR.

The CROSSWALK Editor, the CROSSWALK Editorial Panel and the ASA Committee on Economics appreciates comments and questions about CROSSWALK content. Users are encouraged to submit suggestions using the form found in the CROSSWALK and included with this memo.

Proposed Change or Addition for 2019 CROSSWALK

The effectiveness of the ASA CROSSWALK^® document is dependent upon regular revisions reflecting changes in anesthesia practice.
