I am a fairly new coder so I am not sure about this billing scenario.
Patient came to office on 1-1-xx for lesions. 99213-25 and CPT 17110 were billed. 9 lesions were removed.
Patient came back to office on 1-8-xx for URI. One of the 9 lesions was retreated on that DOS. Provider documents: "all healing but one is left and (pt) wants to retreat".
A. Do I charge again for CPT 17110 since one lesion was "retreated" or NOT because the lesion was one of the original lesions treated and DOS is still within 10 global?
B. E&M would be appended with -24 since OV is within 10 day global of previous procedure (17110) ...correct?
Thx
