A nine-year-old amputee who raised $30k for a prosthetic arm denied by her insurers is paying it forward - and giving the money to another deserving child.

Remington Bateman was born without a left hand and after outgrowing her conventional prosthetic, tried out a robotic 'Hero Arm'.

But she was left devastated when insurer Select Health deemed it 'not medically necessary', her family say.

She launched a GoFundMe - raising $25k in a matter of hours - but then company CrowdHealth stepped in to pay for her arm in full.

She was encouraged to use the GoFundMe donations as she wished - so she decided to help a stranger.

Kind Remington, from Utah, found the fundraising page for Tyraun "Taj" Johnson Jr., eight, from Caroline County, Virginia, also born without a left arm - who was raising money for a bionic limb."

She gave him the money so now both children - born without hands and denied insurance approval their families say - will get Hero Arms.

Open Bionics will make Remington's new arm over Christmas - a multi-grip bionic hand controlled via sensors sat atop muscles in the forearm of the wearer.

"I'm so excited to get my Hero Arm, I could jump to the moon," Remi said. "

"Being able to help Taj means a lot to me."

"As soon as I saw that I had raised enough money to help someone else I wanted to."

Kaitlin Skinner, Taj's Mom, was ecstatic.

"We are just so grateful to Remi and her family," she said. "This is a blessing."

Remi's mom, Jami, added: "Telling Taj's family was just so amazing."

"Every kid deserves a chance and we were so grateful to be able to help them and they were so surprised and grateful to receive the help."

"The reason we shared Remi's story in the first place was to raise awareness of the impact insurance denials have."

"Remi absolutely needs this device to aid her in two-handed tasks and activities. It is going to support her spinal and shoulder health as she grows too. "

"We are thrilled that a company stepped forward to pay for Remi's arm, enabling us to use the donations to help another limb-different family in need. "

"We hope this helps them as much as it helped us."

Jami said Remi was born without a left arm "due to an amniotic band in the womb"."

She needed an upgrade to a robotic arm after using prosthetics which she had outgrown.

After Remi and her family traveled to Colorado, where she had the opportunity to test out a Hero Arm — which costs $24,000 without insurance — her mother received a denial letter from Select Health.

"They've approved three prosthetics before in her lifetime, so I can't figure out why they refuse to deny this one," Jami told KUTV last week."

Upon appealing the decision — which Select Health denied — Jami stated that the arm was "100 percent needed."

With CrowdHealth covering the costs and Open Bionics set to create her new arm, Remi will have greater dexterity — and Taj will receive the same blessing.

Elise Dreiling, Remy's clinician at Open Bionics, noted that the company is "so glad" Remi will receive her Hero Arm. "

"After a careful evaluation, we determined that Remi could utilize this technology to great effect and it would improve her life and health," she added. "

"We hope insurance companies will begin to approve more devices for upper limb amputees that can significantly impact their health and quality of life."

Select Health did not immediately respond to request for comment.
