I was reading your “As the Practice Codes” October 2011 issue about OB billing. I have a mother that delivered on September 22, 2011. My doctors in the clinic have performed the prenatal and delivery. The patient had scheduled a PP follow up visit on 11-16-11 but no-showed the visit. (I typically try to wait until the PP visit has been performed in our clinic to bill out). Most likely if patient does eventually schedule her PP visit, it would probably be at our clinic but none has been rescheduled. So I am trying to decide if I would bill the 59400 (total OB care) (even though no outpatient PP follow up care has been performed at this point) or would I bill out antepartum visits (59426) and delivery only (59409) plus E & M codes after delivery (like 99231, 99238). Just not sure when the patient does not come back in for her PP follow up visit. What would happen if we bill this out and then several months later comes in for PP follow up visit after we have billed?
