Though our office cannot find any documentation or articles from CMS we are now being denied for bilateral procedures. We use a 50 modifier with 1 unit, double price. The denials are for invalid or improper modifier for bilateral hip x-rays. Last time I checked my anatomy book humans still had 2 hips not one. Anyone else experiencing this? ![Confused :confused: :confused:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
