In simple words: This code covers one rigid gas permeable contact lens that is placed on the eye's surface to correct nearsightedness, farsightedness, or astigmatism. This type of lens allows oxygen to reach the eye, promoting healthier long-term wear.

This code covers the supply of a single gas permeable, spherical contact lens for corneal wear to correct refractive errors like myopia, hyperopia, or astigmatism in a healthy eye. These rigid lenses feature a convex anterior surface and a spherical posterior surface conforming to the scleral curve. The posterior surface also facilitates tear exchange between lens and cornea. Gas permeable lenses allow oxygen transmission, preventing corneal edema with extended wear.

Example 1: A patient with myopia requires a gas permeable, spherical contact lens for improved vision correction in their right eye. V2510 is billed for the supply of the lens., A patient with hyperopia and astigmatism is fitted with gas permeable, spherical contact lenses for both eyes. V2510 is billed twice, once for each lens supplied., A patient with keratoconus is fitted with a gas permeable contact lens to improve vision and corneal stability. V2510 is billed once.

Documentation should include the diagnosis necessitating the contact lens (e.g., myopia, hyperopia, astigmatism, keratoconus), the type of lens supplied (gas permeable, spherical), and the eye to which it was fitted (left, right, or both).
