When billing for normal implant maintenance, i.e., cleaning the implants and the IS prosthesis we use code D6080. Where we are confused is how to properly bill for O-ring replacements done at the same time. How do we bill for the O-rings? If O-rings are also billed under D6080 would we bill D6080 twice, once charging for the regular maintenance and the other charging for the O-ring replacements separately? Is this the correct way to do it, or will it be denied? Thank you.
