We're almost to the end of our review of oxygen billing for medical billing practices. So far, we have covered the GX0 record and the GX1 record for NSF 3.01 specifications. In this installment, we're going to cover the GX2 record, which is facility information.

Usually facility information is covered in the E records of a claim. So why do we have to include facility information in a CMN for oxygen billing? The reason is because of the nature of oxygen therapy. Oxygen therapy is strictly regulated because, quite honestly, working with oxygen can be very dangerous. The number of regulations for working with oxygen are enough to choke a horse. That's why there is all this red tape when submitting claims. Therefor, facility information is not only required in the E records but also in the GX2 record for any oxygen claim. In this installment we cover all the fields of the GX2 record.

GX2 field 1, positions 1 - 3, is the record type. This must be filled in with GX2. This record must follow the GX0 and GX1 records in that order or the claim will be denied.

GX2 field 2, positions 4 - 5, is the sequence number. Because there can be as many as 99 CMNs in a claim file, a sequence number is required for each one. The GX2 records are transmitted as GX2-01, GX2-02 and so on. These cannot be out of sequence or the claim will be denied.

GX2 field 3, positions 6 - 22, is the patient control number. This must be the same number that is transmitted in the CA0 record and all subsequent records sending patient information.

GX2 fields 4 - 8, positions 23 - 113, is the test facility information. This is the information that tells the carrier where the facility is located for testing. This must be the actual location where the testing was done and not the parent company address. The reason is because these facilities have to be licensed to dispense and test oxygen.

GX2 fields 9 - 14, positions 114 - 237, is the patient facility information. These fields tell the carrier where the patient resides, if not at home. This can be the same as the facility where the testing is done, but in any case the information must be entered in both plac

Oxygen billing is a very complex process because the treatment of a patient with oxygen is heavily regulated. Because of all the lawsuits being brought against healthcare professionals these days, insurance carriers are even more cautious about medical claims. It may seem like overkill, but an approved claim that results in a lawsuit because if malpractice only ends up costing us all more money in the long run with higher premiums, higher medical costs and higher administrative costs.

This concludes our series on the G records for medical billing of oxygen claims.
