CPT® Code 68040

The procedure described by CPT® Code 68040 refers to the expression of conjunctival follicles, which is a targeted intervention primarily aimed at treating follicular conjunctivitis. This condition is characterized by the presence of swollen, inflamed follicles on the conjunctiva, often resulting from infections, with Chlamydia trachomatis being a common causative agent. The expression of these follicles is essential for alleviating symptoms associated with the infection, such as discomfort, redness, and discharge. During the procedure, local anesthetic drops may be administered to minimize discomfort for the patient. The eyelid is then everted, allowing for a clear view of the conjunctival surface where the follicles are located. By applying manual pressure, the clinician can effectively express any purulent material contained within the follicles, thereby facilitating drainage and promoting healing. This procedure is particularly important in managing cases of follicular conjunctivitis that do not respond adequately to conservative treatments.
