HAGATNA, Guam � A medical vendor that says it is owed more than $500,000 has stopped supplying Guam Memorial Hospital.

Ben Manibusan is general manager of MidWest Medical Supplies. He says some of the hospital�s debt is more than three years old.
Manibusan says his company won�t release any more supplies until the hospital makes a payment of at least $21,000.
The company provides the hospital pharmaceuticals, intravenous solution and sanitary supplies.
Hospital board chairman Dan Webb says the hospital owes about $8.6 million to its vendors. He says about $5.2 million is more than 90 days past due.
Hospital spokesman Connor Murphy says the hospital faces several financial challenges, including a patient population where a quarter of patients are uninsured self-payers.
