A rising number of Texas primary care practitioners are switching to a cash-based model to avoid the bureaucracy of the health insurance system and high processing costs, The Texas Tribune reported. Under the "direct primary care," physician practices can cut costs because they don't need additional staff associated with accepting coverage. Cash-based practices treat mostly uninsured patients, although patients who have insurance but want to avoid paying thousands of dollars to meet high deductibles also have shown interest in direct primary care. However, some industry experts warn that too many practitioners embracing the cash-based model could leave the state struggling to find doctors to treat insured patients as the healthcare reform law requires coverage for most Texans.
