I'm reading the LCD for debridements which inform me to code to the deepest tissue removed but notice that per they contract with a HMO ins. the company bills the codes that the ins agreed to pay. they justification is that in order to get to the deepest tissue, the clinican passed the other tissues. My judgement that this is undercoding. The right way would to get all codes associated with the practice on the contract. or contract to state "that regardless to what is performed you will only be reimburse for contractual procedures". The coders are being asked to code the procedures according to contract. I disagree with this method. I wonder if there any edvidence besides coding guidelines from the LCD.
