Dispensing (Quantity vs. Time) Limits

Dispensing limits are edits that prevent prescription claims from being processed and paid by the health plan if a member is receiving more than the clinically appropriate amount of medication over a stated period of time.

The objective of dispensing limits is to improve the quality of pharmaceutical care in order to obtain appropriate outcomes and to address inappropriate utilization at the time of dispensing to minimize health risks and reduce overall costs.

Limits are typically developed based on FDA-approved drug labeling.

The Dispensing Limits Drug List provides a listing of all the drug classes and drugs that are subject to dispensing limits:
