[The following is a wild and crazy idea to improve the clinical effectiveness of a health care encounter.]   In addition to the 'usual' information returned in response to a health care eligibility request, also return a list of all medications dispensed that the health plan and its Pharmacy Benefit Managers (PBM) and other business associates have in their files.  For medications dispensed by retail pharmacies, send both a textual description of each medication and the corresponding NDC value.  For medications dispensed from other than retail pharmacies, send a textual description plus a code set name qualifier (e.g., Medispan, First Data Bank) and the applicable drug code from that code set.  At this stage of health care, any such information is better than none at all -- which is often the present situation.
