In most groups, the electable options are limited to two or three. When the above semi-retirement options are agreed to, compensation arrangements relative thereto need to be determined as well. Sometimes a set percentage of what a full-time physician is earning is the answer. In others, a purely productivity-based compensation arrangement is the answer. There is no one formula that works in each instance.
Different practices place different weights upon different pieces of the puzzle.
Some groups will just never allow part-timers in the practice. Each situation is different. If properly structured, it will allow a senior physician to continue to work in a reasonable fashion at a fair compensation. In some situations, the senior doctor's managerial experience is viewed as a positive that the group would lose if this new work arrangement were not developed. This is becoming more popular than ever in group practices today.
