AHRQ’s CCSR groups this code into broader clinical categories.

• Electronic Nose

  a device used to detect airborne odors, gases, flavors, volatile substances or vapors.

• Fasciculation

  involuntary contraction of the muscle fibers innervated by a motor unit. fasciculations may be visualized as a muscle twitch or dimpling under the skin, but usually do not generate sufficient force to move a limb. they may represent a benign condition or occur as a manifestation of motor neuron disease or peripheral nervous system diseases. (adams et al., principles of neurology, 6th ed, p1294)

• Glossitis, Benign Migratory

  an idiopathic disorder of the tongue characterized by the loss of filiform papillae leaving reddened areas of circinate macules bound by a white band. the lesions heal, then others erupt.

• Oral Frenectomy

  surgical procedures to release or remove abnormally short or tightly attached frenum (e.g., lingual frenum or labial frenum) associated with a pathological condition (e.g., tongue tie and lip tie).
