An answer in “Coding and Documentation” [July/August 1999, page 12] gave incorrect advice regarding use of the CPT codes for prolonged services. The amount of time that CPT indicates is typically associated with the level of office visit provided should be subtracted from the time actually spent in face-to-face contact with the patient. The result of that calculation should guide the selection of the prolonged services code. For an example, see “Calculating prolonged services” on page 23.
In “The Family Practice Management Practice Self-Test,” [February 2001, page 41], we inadvertently failed to acknowledge the considerable contributions of Marc L. Rivo, MD, MPH, medical editor of FPM, to the development of the self-test. Our apologies, Dr. Rivo!
