April 8, 2019 Re: Kathryn Dirkes Bass, M.D. Thank you for your recent inquiry to the American Board of Surgery (ABS) regarding the certification status of the above named surgeon. The specific status of this surgeon with the ABS is listed below. Surgery Current Status: Certified Meeting CC Requirements Certificate #042956 Initial Certification Date: February 11, 1998 Reverification Date: December 31, 2019 Pediatric Surgery Current Status: Certified Meeting CC Requirements Certificate #000880 Initial Certification Date: March 29, 2004 Expiration Date: December 31, 2024 THE REVERIFICATION DATE (ABOVE) IS PROVIDED FOR CREDENTIALING PURPOSES. As part of the ABS’s Continuous Certification Program, Board certification is contingent upon meeting the ongoing requirements of the program. Surgeons who were initially certified and/or took the continuous certification assessment after September 2018 are issued certificates with no end dates to certification. For surgeons without an expiration date on their certification(s), annual primary source verification on or immediately after the reverification date (annually on December 31) is necessary to accurately determine a surgeon’s current certification status. Please inform us immediately if your information differs from what we have supplied above. If you have questions regarding this information, please contact the ABS office. Jo Buyske, M.D. Executive Director 1617 John F. Kennedy Boulevard Suite 860 • Philadelphia, PA 19103 • ph. 215.568.4000 • www.absurgery.org
