How do you measure excision of a lesion?

When coding lesion excisions, when you take measurements is just as important as how you take them. According to CPT, to determine the appropriate lesion excision code, you must measure the lesion’s diameter at its widest point and add to that measurement double the width of the narrowest margin.Click to see full answer. Similarly one may ask, how do you calculate excision of a lesion?In plain language, the excised diameter equals the length of the lesion at its longest point, plus two times the narrowest margin. For example, if the lesion measures 1 cm at its greatest, and the surgeon removes a margin of 0.5 cm on all sides, the total excised diameter is 2.0 cm (1.0 cm + [2 x 0.5 cm]).Beside above, how are skin lesions measured? CPT® specifies that to find a final measurement, you add together the largest diameter of the lesion, plus twice the smallest margin (3 cm + 0.5 cm x 2 = 4 cm). The payment difference between 11403 and 11404 is small—approximately $10, on average, for Medicare payers—but over time these amounts can really add up. Also to know is, what is excision of lesion? Skin Lesion Excision. Skin lesion excision is a procedure in which the surgeon removes a cancerous skin lesion and an area of surrounding tissue called the margin. Many types of benign skin growths may look like malignant tumors and are removed for a biopsy.How should the excision of multiple lesions be reported? Coding Information If there are multiple lesions treated, multiple codes may be reported but you must follow National Correct Coding Initiative guidelines. CPT code 11200 should be reported with one unit of service. CPT code 11201 should be reported with 1 unit for each additional group of 10 lesions.
