It pits doctors — represented by the politically powerful California Medical Assn. — defending their turf against other medical providers. They're nurse practitioners, optometrists and pharmacists.  In political speak, it's about "scope of practice" — the type of medical care non-doctors are allowed to provide. The war has been waged for many decades, at times also involving chiropractors, podiatrists and any number of medical professions trying to encroach on the docs' terrain.  Mostly, the well-heeled docs have held their ground.  But now the nurse practitioners, optometrists and pharmacists are attacking all-out, fighting for a larger chunk of the action to be funded by Obamacare, officially called the Affordable Care Act.  When the act kicks in next January, most Americans will be required to buy health insurance or pay a penalty.  In California, that is expected to swell the insurance rolls by 4 million to 5 million people. (About 7 million currently are uninsured, but that includes illegal immigrants, who won't be eligible for Obamacare.)  There simply won't be enough doctors to care for all the newly insured, contend the turf invaders.  "If we're going to be mandating that everyone have health insurance, it's incumbent on the Legislature to make sure they have access to care," says state Sen. Ed Hernandez (D-West Covina), chairman of the Senate Health Committee. He's also an optometrist.  There seem to be ample primary care physicians in most urban areas. But Hernandez says there are major shortages in rural regions and minority communities. An estimated two-thirds of counties lack enough doctors. Moreover, around a quarter of the physicians are at retirement age.  Hernandez is pushing three bills (SB 491, 492, 493) that would allow, for example, nurse practitioners — more highly trained than RNs — to open their own shops and operate separately from physicians, who now are their supervisors.  "They wouldn't do anything above and beyond what they're now doing," Hernandez says, "But they'd be more accessible in inner cities and rural areas."  Optometrists, however, would be permitted to expand their scope of care for such maladies as diabetes.  Pharmacists could "do direct patient management," Hernandez says. "Prescribe birth control pills, smoking cessation pills…. Pharmacists are the most overly trained and underutilized professionals we have."  "This is all very contentious," the senator adds.  It amounts to a full-time employment act for lobbyists.  The California Medical Assn. spent $2.9 million on lobbying during the last legislative session and funneled $1.2 million into campaign contributions during the 2012 elections. It donated $500,000 to Gov. Jerry Brown's tax-increase measure, Proposition 30.  Seventeen states allow nurse practitioners to operate independently, but the CMA is opposed.  "They need supervision," says CMA President Paul Phinney, a Sacramento pediatrician.
