NASHVILLE (AP) — Tennessee officials have revoked the medical license of a Goodlettsville physician.

The Tennessee Board of Medical Examiners said Dr. Warren T. Hill's license to practice medicine was revoked for "unprofessional, dishonorable or unethical conduct," according to The Tennessean (http://bit.ly/ny8uIK ).

In also surrendering his federal certificate to prescribe narcotics, Hill conceded he was a poor record keeper.

Hill co-founded Urgent Care and Diagnostic Center in Goodlettsville. The action was taken after the Department of Health reviewed 16 of Hill's patient records. He voluntarily surrendered his license and his federal certificate.

The board previously disciplined Hill in 2009 and 1997.
