Corneal Pachymetry (July 2004)
July 2004 page 12 Coding Communication:Corneal Pachymetry In recent years, pachymetry has become an important component of the accurate diagnosis of glaucoma. This article will define glaucoma before explaining corneal pachymetry. Glaucoma Stedman’s Medical Dictionary defines glaucoma as “a disease of the eye characterized by increased intraocular pressure and excavation and atrophy of the optic nerve. It produces defects in the visual field and may result in blindness.” When the intraocular pressure in the eye increases, it damages the optic nerve, potentially resulting in decreased peripheral vision and even blindness. Open-angle glaucoma and angle-closure glaucoma are...

Article Overview
This July 2004 coding communication addresses corneal pachymetry as part of glaucoma evaluation and management. It reviews the clinical context for measuring corneal thickness, notes the CPT code update for the service, and presents a procedural overview and clinical example to help readers understand the subject area and relevant coding framework.
Why This Topic Matters
The article is relevant to ophthalmology and coding professionals who need to recognize when corneal thickness measurement is discussed in relation to glaucoma care and how the service was represented in CPT at the time of publication.
