Postoperative Ventilator Diagnosis Coding


By Dr. Richard Pinson, MD, FACP, CCS

Q: What diagnoses could be compliantly used when a patient comes to the ICU on a ventilator from surgery and needs some more time to let the anesthesia wear off from a long OR time?

A: Any diagnosis submitted on a claim must meet the test of “clinical validity.” According to CMS: “Clinical validation involves a clinical review of the case to see whether or not the patient truly possesses the conditions that were documented in the medical record.”

Documentation of postprocedural respiratory failure or pulmonary insufficiency sometimes occurs when patients are mechanically ventilated for several hours following surgery. For clinical validity, the patient must have acute pulmonary dysfunction requiring non-routine measures and/or prolonged respiratory support. Clinicians may check for a PaO2/FIO2 <300 which would confirm acute hypoxemic respiratory failure on vent.

In an uncomplicated, routine, postoperative ventilator setting, the patient’s primary problem is usually some degree of depression of the brain’s respiratory center (code G93.89) during routine recovery from anesthesia and physiologic stress of surgery. Do not use “ventilator dependence” (Z99.11) reserved for patients who are chronically dependent on a ventilator.
