Question: When using code 99050 (after hours), do I just add a amount, example $25.00, to our normal total charges for that patients visit?

Answer: 99050 is a stand alone code that reports for after hours. You would establish a fee for this service itself. Any other services performed on the after hours visit would be billed accordingly at their typical fees. For example, if you saw a patient on a weekend, adjusted them 3-4 regions of the spine and performed e-stim, your coding may look like this: 99050 98941 G0283
