The procedure described by CPT® Code 11977 involves the removal and reinsertion of implantable contraceptive capsules, which are small devices that release hormones to prevent pregnancy. These capsules are designed to be inserted under the skin, typically in the upper arm, where they can provide effective contraception for a duration of 3 to 5 years. The process begins with the physician administering a local anesthetic to minimize discomfort during the procedure. A small incision is made in the skin to access the capsules. If the capsules need to be removed, the physician will locate them by palpating the area; if they are not easily felt, imaging such as a radiograph may be used to assist in their identification. Once the expired capsules are removed, new capsules are then inserted using a trocar, ensuring that they are placed in a fan-like configuration if multiple capsules are used. This procedure is crucial for patients who wish to continue using hormonal contraception without interruption, as it allows for the seamless transition from old to new capsules.
