Is anyone aware of any guidelines relating to destruction of nail matrix cpt 11750 partial ; lateral or medial performed at two separate visits ? My experience has always been that you can only bill one 11750 per toe. However, the situation we were presented with,not once but twice ,was that we did a partial matrix of the lateral border and then a week later patient presents with medial border ingrown and the doctor performs another 11750 of the same toe. Can this be billed separately if documentation supports a new condition ?
