* Big victory for Planned Parenthood
* Texas appeals federal judge's injunction
* Ban would have affected thousands of women (Adds statement from governor's office, background)
AUSTIN, Texas, April 30 (Reuters) - A federal judge on Monday temporarily blocked a new Texas rule that would have banned state funding for Planned Parenthood clinics and ended their health services for poor women because the organization provides abortions.
The ruling by U.S. District Judge Lee Yeakel in favor of Planned Parenthood means thousands of women enrolled in the Texas Women's Health Program who go to its clinics will not have to find new healthcare providers, at least for now.
"The court is particularly influenced by the potential for immediate loss of access to necessary medical services by several thousand Texas women," Yeakel said in a 24-page ruling.
The preliminary injunction is a big victory for Planned Parenthood, which has been under siege in several states by abortion opponents. In the past year alone, states including Wisconsin, North Carolina, Tennessee and Indiana, in addition to Texas, have moved to block Planned Parenthood from receiving taxpayer money.
"For many women, we are the only doctor's visit they will have this year," Cecile Richards, president of Planned Parenthood Federation of America, said in a statement. "This ruling affirms what women have known all along: politics simply doesn't have a place in women's health."
Texas Governor Rick Perry and some Republican lawmakers have said they would rather eliminate the women's healthcare program entirely than direct money to Planned Parenthood clinics.
Texas immediately appealed the federal judge's decision.
"Texas has a long history of protecting life, and we are confident in Attorney General Abbott's appeal to defend the will of Texans and our state law, which prohibits taxpayer funds from supporting abortion providers and affiliates in the Women's Health Program," the governor's press secretary Catherine Frazier said in a statement.
The Texas program, which is part of the federal-state Medicaid program, provides cancer screenings, birth control and other health services to more than 100,000 low-income women.
The program does not pay for abortions or allow abortion providers to participate in the program. The new Texas state rule would ban program money from going to affiliates of abortion providers.
State law has included that ban on affiliates since the program began in 2007, but the state did not enforce it. Texas notified the federal government last year that it intended to begin enforcing the ban, effectively excluding Planned Parenthood from the program.
On March 9, the administration of President Barack Obama announced that it would no longer provide funding for the Texas program if Planned Parenthood was excluded. Texas then filed suit against the federal government. The ruling on Monday was on the Texas suit.
According to Planned Parenthood, about 49 percent of the women who received services through the program in 2010 obtained some services through a Planned Parenthood provider. Planned Parenthood said it would lose about $13.5 million of annual funding for preventive care and family planning if the rule is applied, forcing it to close clinics and lay off staff.
Texas has already made deep cuts in other family-planning programs. As a result, state subsidies that once provided low-cost birth control to 220,000 women a year now cover fewer than 60,000 women a year.
The federal government pays for 90 percent of the cost of the Texas Women's Health Program, which serves low-income women of reproductive age who do not qualify for regular Medicaid coverage. Texas puts up just $4 million a year.
Critics object to Planned Parenthood receiving taxpayer money, which cannot be used to provide abortions, arguing that a steady stream of government grants provide an indirect subsidy by helping pay utility bills and keep doctors on staff.
Planned Parenthood is the nation's largest abortion provider, terminating about 330,000 pregnancies a year.
It gets about a third of its revenue - $360 million in 2009 - from government grants to provide birth control, gynecological exams and care for sexually transmitted diseases to low-income women. (Reporting by Corrie MacLaggan and; Writing by David Bailey; Editing by Greg McCune and Anthony Boadle)
