Code Section 12-36-2120(28) exempts from the sales and use taxes:
To assist in the administration of this exemption, the Department has adopted definitions for the terms "medicine" and "prosthetic devices" as follows:
"Medicine"--a substance or preparation used in treating disease.
"Prosthetic Device"--an artificial device to replace a missing part of the body.
The sale of prescription lenses that replace a missing part of the eye are exempted from the tax, as for example eyeglasses prescribed for a person whose natural lenses have been surgically removed.
Eyeglasses, contact lens, hearing aids and orthopedic appliances, such as braces, wheelchairs and orthopedic custom-made shoes, do not come within the exemption at Code Section 12-36-2120(28). However, sales of hearing aids are exempt pursuant to Code Section 12-36-2120(38).
Hypodermic needles, insulin, alcohol swabs, blood sugar testing strips, monolet lancets, dextrometer supplies, blood glucose meters, and other similar diabetic supplies sold to diabetics are only exempt if sold pursuant to the written authorization and direction of a physician.
