Procedure code #83901

The insurance provider denied #83901 stating "this service represents an add on that is only consdered for reminbursement when reported with a primary procedure that is also considered for separate reimbursement".

Does this want me to submit 83900 as one unit, and then 83901 x the number of units with a modifer?

83901

How many sequences did you do?

Are you billing the 83900 and the 83901? You cant use the 83901 unless you use the 83900 first.

83900 should be billed as one unit, and covers your first two sequences.
83901 should be billed for each add'l sequence... so you may have multiple units.

Do I use a Modifer w this

So, if since there are a total of 5 units.
I should bill 83900, then 83901 x 4 units for a total of 5 units?
Should I use a Modifer for 83901 because it is x 4 units?
