Pharmacy benefit management (PBM) companies combine retail pharmacy claims processing, formulary management and home delivery pharmacy services to create an integrated product offering to manage the prescription drug benefit for payors. Some PBMs now provide specialty services to provide treatments for diseases that rely upon high-cost injectable, infused, oral or inhaled drugs which provide a more effective solution than many retail pharmacies. PBMs also have broadened their service offerings to include compliance programs, outcomes research, drug therapy management programs, sophisticated data analysis and other distribution services.
