We have been getting denial on patients that come in for annual mammogram screenings with Tomosynthesis. These patients have had a unilateral mastectomy. For example, the patient came in for a Mammogram screening with Tomosynthesis of the left breast we would code is as follows:
77067-52, LT, Z85.3 (hx of breast CA), Z90.11 (absence of right breast)
Is this correct? This is how we coded them, and recently we have been getting denials. Please help!!
