What code should be used for a simple excision of a skin lesion?

For a simple excision of a skin lesion, the correct code is 11400. This code is specifically designated for the excision of benign skin lesions that are less than 2.0 cm in diameter. It encompasses the entire procedure, including any margins that may be necessary to ensure complete removal of the lesion, as well as the closure if applicable.

The codes in the other options pertain to excision procedures as well but are distinct in their specifications. For instance, the code 11402 refers to excision of a benign skin lesion measuring between 2.1 cm and 3.0 cm, indicating a different scope of procedure compared to 11400. Similarly, codes 11404 and 11406 pertain to excisions of lesions larger than 3.0 cm, marking a need for different coding based on size and complexity of the excised lesion.

Thus, when coding for a straightforward excision of a benign skin lesion less than 2.0 cm, 11400 is the appropriate choice as it accurately reflects the procedure performed.
