HCPCS Code V2521: Contact Lens, Hydrophilic, Toric, or Prism Ballast, per Lens

HCPCS code V2521 is defined as "Contact lens, hydrophilic, toric, or prism ballast, per lens" and is used to report monthly hydrophilic toric contact lenses designed to correct astigmatism. This code applies only to soft (hydrophilic) toric or prism ballast lenses. It should not be used for rigid lenses, such as translating multifocal GP lenses, corneoscleral lenses, or PMMA scleral lenses, which have their own codes.

Medicare generally does not cover HCPCS code V2521 when these hydrophilic toric or prism ballast contact lenses are used for the treatment of non-diseased eyes with spherical ametropia, refractive astigmatism, or corneal astigmatism.

A medically necessary contact lens diagnosis refers to specific medical conditions of the eye that justify the need for specialized contact lenses as part of treatment. These diagnoses typically involve corneal or ocular abnormalities that cannot be effectively managed with standard glasses or lenses.
