Are you playing a zone defense?
If there's an aspect of your practice you're uncomfortable facing, whether it is your checkbook, collections, new patients or even missed appointments, it's tempting to turn over its responsibility to someone else. This is often justified as a way of freeing you up for duties that are "more important." These more important aspects are usually areas where you feel more competent and confident.
Compartmentalizing your practice by delegating issues to others so you don't have to face them, is how many practices get into trouble. It turns out you're the only person on the planet who sees these "peripheral" issues as being separate! Since it's your practice. You're responsible for EVERY aspect. Not just the ones you like or are especially resourceful in handling.
By all means, delegate. Supervise. Expect accountability. But be unafraid to look at anything and everything. Because it's all your responsibility. Even the unpleasant parts.
