I work in a facility with over 100 providers and there are several instances per week where a direct LDL, CPT 83721 is ordered with a lipid panel, CPT 80061. NCCI policy manual states that these tests may be reasonable and necessary IF the triglyceride level is greater than or equal to 400mg/dl (too high to permit calculation of the LDL). Does that mean we have to check each result before adding the -59 modifier to 83721?
