I do not have access to a 2009 CPT code book. I work for a Cardiologist who recently recieved an audit for billing a 93510 (left heart cath) with an E &M code 99238 (hosp discharge) on the same day. I was wondering if anyone could give me some assistance with this please. I would be greatful for any info that I could share with my physician to cover the 2009 guidelines. Thank you for your help!!
