Harmonycares

HarmonyCares is a physician-led, value-based, in-home primary care organization headquartered in Troy, Michigan, and one of the nation's largest house-call practices. It brings primary care, palliative care, and ancillary services such as in-home laboratory, radiology, and comprehensive health assessments directly to older adults living with serious and complex chronic conditions. Operating across roughly a dozen states, HarmonyCares supports more than 70,000 patients through value-based arrangements with Medicare Advantage plans and Medicare ACO programs. The company was surfaced through the API Evangelist network as a General Catalyst portfolio company; it publishes a public marketing site, a patient portal, and corporate policy documents, but no public developer program, API, or SDK was found during enrichment.
