Every Optometrist practice or Doctors of Optometry face challenges in coding and billing. Professional coding and billing expertise is necessary to code and bill primary eye care claims. Optometry coding and billing is complex and requires experienced, trained and certified coders to accurately code the procedures such as routine eye exam,refractions, ophthalmic diagnostic imaging, optic nerve, fundus photography, contact lenses, perimetry testing, OCB (Optical coherence biometry), fluorescein angiography, refractive vision exams, binocular and accommodative tests, retinoscopy, ametropia, binocular and biocular balance refraction in VL, stereopsis, convergence, phoria, opthalmoscopy, pupillary functions, ocular tonometry, biomicroscopy etc.
