Recently, we have noticed that when we bill revision/removal of a sling (57287) and cystoscopy (52000) together, Medicare pays both procedures at 100%. After speaking with a representative at Medicare, she explained that the claims are being paid correctly due to a change that went into effect 1/1/2014. She was unable to direct me to documentation of this change and I can't find anything on the CMS website or even Google. Has anyone else noticed this or can anyone enlighten me on this particular change? Please help!
