All claims with initial certifications calling for oxygen flow rates of more than 4 liters per minute must be reviewed before payment is authorized.

Items Requiring Special Attention -

a. Oxygen Delivery or Supply Prescribed - If the treating physician has specified the oxygen equipment to be supplied, contractors ensure that the equipment furnished is consistent with that prescribed.

b. Treating Physician Identification - Contractors must ensure that the CMN or Form CMS-484 has been signed by the treating physician. A stamped signature is unacceptable. The physician's identification number must be the Unique Physician Identification Number (UPIN).
