One of the fascinating things about Land Hermit Crabs is that they live in other creatures discarded shells. As they grow they will leave their old shell and find another larger one to move into. To assist the crabs with this, a few spare shells should be kept in the aquarium for such occasions.
The case involved multiple medical conditions and procedures is properly coded as Diagnosis Codes 366.16 (cataract) and 365.10 (glaucoma) and CPT Codes 66982-RT (right eye complex cataract surgery) and 66180-RT (right eye revision of an aqueous shunt/Aquaflo prosthesis).
This code is designated as a separate procedure in the CPT Manual. Use code 20680 for deep pin removal procedures, (which are usually done in an ASC). The physician makes an incision overlying the site of the implant using deep dissection to visualize the implant (usually below the muscle level and within bone).se code 20670 for superficial pin removal when the physician makes a small incision overlying the site of the implant, and the physician removes the implant by pulling or unscrewing it. The incision is closed with sutures/steri-strips (no layered closure is involved).
