One of the biggest 2017 CPT changes is in interventional radiology and the new ability to separately bill and be paid for moderate sedation provided during certain procedures. While trend has been to bundle payments, this is an opportunity to unbundle and receive additional payment for services that were previously bundled in the base procedure code. The importance of proper documentation of moderate sedation can’t be stressed enough. Proper code selection and accurate reimbursement depend on clear and concise documentation. The new Moderate Sedation codes are 99151-99157.
