When you-re coding for the microscope use, find out which type of magnification your physician is using. You-re looking for terms such as "operating microscope," "surgical microscope," "binocular microscope," or "telescope" and brand names such as Zeiss, Weck or Leica. Operating microscope: An operating microscope is a large, expensive piece of equipment found in an operating suite. It's binocular -- that is, it has two eyepieces (or even two sets of eyepieces). This is typically the equipment to which +69990 refers. Binocular microscope: This is a smaller piece of equipment that you are likely to find in your ENT's clinic. This is typically the equipment you use 92504 to indicate. Telescope: An ENT inserts a telescope into the patient's throat or nose. Treat a telescope the same as an operating microscope used with an endoscope for purposes of coding many procedures, such as 31526 (Laryngoscopy, direct, with or without tracheoscopy; diagnostic, with operating microscope or telescope). These are included in the codes that indicate both endoscopy and microscopy. Other lenses: Don't confuse a microscope or telescope with a loupe (which may fit over a pair of glasses) or the ENT's hand-held otoscope. If your ENT is using lesser equipment, don't even consider coding for microsurgery.
