The current procedural terminology (CPT) code used to report the removal of a cyst depends on criteria such as lesion type, location and size. For a benign cyst excision, the CPT codes are from 11400 to 11446, and for the removal of a malignant lesion, the CPT codes are from 11600 to 11646, as noted by the American Academy of Professional Coders. The specific location of the cyst on the body determines the exact CPT code used for reporting its removal.
For the excision of a benign cyst on the trunk, arms or legs, the CPT codes assigned can be from 11400 to 11406 and 11440 to 11446 for different areas of the face or ears. Similarly, a malignant lesion that is removed from an area of the face may have a CPT code from 11640 to 11646.
Along with the CPT code, other information used to report removal of lesions are their diameter sizes. The diameter size of the excision is given by adding together the lesion length at its biggest point and twice the narrowest margin necessary to completely excise the lesion, as noted by the American Academy of Professional Coders.
Additionally, besides the CPT codes used for excisions of either malignant or benign lesions, there are other CPT code for other types of procedures on cysts, such as shaving and the use of laser surgery. For example, the CPT codes for shaving of a benign lesion are from 11300 to 11313, as noted by Blue Cross Blue Shield of Mississippi.
