Hanger Orthopedic, the nation's largest maker of prosthetic and orthotic devices and an operator of patient care centers, reported a loss of $34.9 million ($1.68 a share) for the three months ended Sept. 30, compared with a profit of $8.7 million (32 cents) for the same period a year earlier.

Executives with the Bethesda-based company said the quarter would have been profitable if not for a $45.8 million adjustment for "non-cash goodwill impairment." The charge reflects the impact of allegations of improper billing at a West Hempstead, N.Y., patient care center. In August, Hanger restated expenses for the past three years, cutting earnings for that period by $2 million. An outside firm hired by Hanger to investigate the billing allegations concluded in August that any billing problems were isolated at the West Hempstead unit.

The U.S. attorney's office for the Eastern District of New York in June subpoenaed Hanger officials for information regarding 14 patient care centers in downstate New York, including the West Hempstead office. During a conference call yesterday, Hanger officials said the U.S. attorney has amended the subpoenas to cover only the West Hempstead location. The company said it has turned over requested information.
