I recently passed my CPC-H exam and don't have the required experience so am an apprentice for the time being. Right now I work as a biller in a local hospital. I had a claim with several CPT codes with modifier 59 and one with modifier 79. I work at a Critical Access Hospital so pro fees are on the claim along with the facility fees. This particular claim was bill type 851. I don't believe the modifiers are being used correctly so I posed my questions to my supervisor who checked with HIM and the person who coded the account. I was told it was correct and to send the claim. I did but I still don't think it is correct. I don't think the modifiers are being used correctly. The CPT codes on the claim were as follows: 96360-59; 96361; 88304; 47562; 44005-59; 94664; 94667-59; 94668; 96372-59; 96375-59; and 47562-79. The patient was in observation for 17 hours. I don't think -79 is correct at all nor do I think -59 is correct on 44005. Can anyone help clarify for me why this claim is correct? Thanks!
