Hi Guest! D4266 – guided tissue regeneration – resorbable barrier, per site This code listed above does not have a direct crosscodes we are aware of – so you can either bill the “D” code on the medical claim (many insurers these days will process “D” codes when they are medically necessary services), or you can use the CPT code below and include a narrative report describing the procedure: 41899 – Unlisted procedure, dentoalveolar structures Hope this helps!
