Patients aren't the only ones confused about Obamacare. Doctors are, too, says Albert Santalo, chairman and CEO of CareCloud—an IT provider to doctors' offices.
"Doctors are struggling," he said in a "Squawk Box" interview on Tuesday. "They're struggling with reimbursement. They're struggling with the complexity of the industry."
Patients are also struggling with the complexity of Obamacare and the technical problems on the federal online store designed for uninsured Americans to buy health coverage.
So the Obama administration on Monday said it is granting a six-week extension until March 31 for Americans to enroll. Under the new policy, people who sign up by the end of the open enrollment won't face a tax penalty. The previous deadline was mid-February.

In May, CareCloud surveyed about 5,000 physicians, and nearly half said "increased operational and billing pressures" will leave them unable to accept the flood of patients expected to join the health care system as a result of Obamacare.
"It's really hard for doctors to stay current with all of the legislation and requirements," Santalo said. "CareCloud is all about taking all of that complexity away from the physicians and allowing them to practice medicine."
Meanwhile, CareCloud and another health care IT company, ZocDoc, are announcing a partnership. ZocDoc allows patients to book doctor appointments online and through its mobile apps.

"CareCloud systems are the scheduling systems in the office. ZocDoc systems open up that schedule to allow better-access to care for patients," Santalo said.
ZocDoc will fully integrate into CareCloud's national physician platform, which provides thousands of doctors with electronic health record and practice management solutions, including billing.
