Medical Billing - GP0 Record Fields 22 Through 33

We're finally coming to the end of our review of the GP0 record for medical billing of claims via electronic media, using NSF 3.01 specifications. In this installment we'll be covering the last twelve fields, which is where most of the differences are between the parental nutrition CMN and the enteral nutrition CMN, which we reviewed previously when we covered the GE0 record. We pick up this installment with field number 22.

GP0 field 22, positions 78 - 92, is the amino acid name. This is the field that tells the carrier the name of the amino acid that is being administered to the patient. This field must be filled in with the actual name of the acid. No abbreviations or brand names allowed.

GP0 field 23, positions 93 - 96, is the amino acid volume. This field tells the carrier how much of the amino acid the patient is to receive per day, not per feeding, for parental nutrition therapy. This amount is transmitted in milliliters and must be exact.

GP0 field 24, positions 97 - 101, is the amino acid concentration. This field tells the carrier what the exact percentage of concentration is for the amino acid that is being given to the patient for parental nutrition therapy. In this case, a decimal is used to show a concentration that is less than a whole percentage, like 10.5%.

GP0 field 25, positions 102 - 105, is the amino acid weight. This field tells the carrier how much the amino acid that is given per day, weighs in grams. If the number of grams prescribed per day is greater than 100, then a narrative explanation must be given in field number 31.

GP0 field 26, positions 106 - 109, is the dextrose volume. This field tells the carrier how much dextrose is in the prescription given to the patient, per day. This field is transmitted in milliliters and must be exact.

GP0 field 27, positions 110 - 114, is the dextrose concentration. This field tells the carrier what the percentage of dextrose is, in relation to the entire solution given to the patient on a daily basis. As with field number 24, a decimal is used if not a whole percentage.

GP0 field 28, positions 115 - 118, is the lipids volume. This field tells the carrier what the volume of lipids is given to the patient on a daily basis. This field is also transmitted in milliliters and must be exact.

GP0 field 29, positions 119 - 123, is the lipids concentration. This field tells the carrier what the percentage of lipids is in relation to the whole mixture, given to the patient on a daily basis.

GP0 field 30, positions 124 - 126, is the lipids frequency. This tells the carrier how many times per week lipids are used in therapy.

GP0 field 31, positions 127 - 226, is the narrative field. This field is used to give the carrier any information that is not covered above that is required, such as explanations.

GP0 field 32, position 227, is the administration technique indicator. This field is used to tell the carrier how the parental nutrition is being administered. Valid entries are N, G, J, or O.

GP0 field 33, positions 228 - 320, is filler national and must be filled with spaces.

In our next installment of medical billing, we'll cover another in the long list of CMNs.
