An independent practice association (or IPA) is a US term for an association of independent physicians, or other organization that contracts with independent physicians, and provides services to managed care organizations on a negotiated per capita rate, flat retainer fee, or negotiated fee-for-service basis.
There are four basic models of Health Plans: 1  Group Model Health Plan: This type of Health Plan contracts with doctors organized as a partnership, professional corporation or other association. 2  IPA Health Plan: The Health Plan contracts with an association of medical professionals to provide medical services in return for a negotiated fee. The IPA in turn contracts with physicians who continue in their existing individual or group practices.
