Please advise on this and if you need more explanation, please contact.
Per the ADA coding companion, you would code D6545 for the retainer tooth and D6242 for the pontic. Any D-999 codes are typically NCB and depending on your contract may also not be billable to the patient. These 999 codes should also be used as a last resort and cannot be used for additional lab fees either.
