The coders in our facility recently had conflicting views on this subject. An inpatient was placed on Bi-PAP. Previously this has not been coded as a procedure for any type visit. One of the coders questioned as to whether we should be coding this as there is a code for a noninvasive mechanical ventilation (93.90). Simply because we had not previously coded this does not mean that we should not have been or should not now. Anybody have any further info on this? There is a charge for it on the account. We have not prevoiusly heard any feedback from the Business Office about needing this code on the account since there is a charge. Should we be coding this procedure on inpatients and/or all accounts?
