• Is it common to bill a patient as D1110 after D4341 and D4910? I read the previous posting related to this topic, but I'm looking for an answer regarding D1110. Our new hygienist has recently seen a patient who has had D4341 and many subsequent D4910's, and charted the visit as D1110. Her notes state that the patient has deep pockets and heavy generalized plaque and stain. I was taught once a perio patient always a perio patient. If this is not correct, please explain why and if the visit should be billed out as D1110. If not, then D4910? Thank you!
