Pay for performance (P4P) is causing physicians to examine how they provide care individually and collectively within local health systems. It is the most recent attempt by Medicare and commercial payers to reduce the cost and improve the outcomes of health care. Understanding P4P and deciding how to manage the multiple programs being implemented by payers will challenge physicians' ethics and practice resources. Improving health care for musculoskeletal diseases will require cooperation among the specialties that share responsibility for this care and improved methods for coordinating and documenting it.
