Report CPT 11400 for benign (noncancerous) lesion removal for lesions on the legs, trunk, or arms with a diameter of 0.5 centimeters or less.
1. What Is CPT Code 11400?
CPT 11400 covers the excises of a noncancerous lesion with a diameter of 0.5 centimeters or less, including the margin. The lesion can be on the patient’s arms, legs, or trunk.
The official description of CPT code 11400 can be found in the CPT book: “Excision, benign lesion including margins, except skin tag (unless listed elsewhere), trunk, arms or legs; excised diameter 0.5 cm or less.”
The provider begins the 11400 procedure by prepping the patient and applying local anesthesia to the lesion area.
Next, the provider takes a scalpel or another similar instrument and holds it perpendicular and gently to the lesion before excising down into the subcutaneous.
Then, they cut into the tissue with an elliptical shape and remove the lesion of 0.5 centimeters or less. The benign lesion might be sent to a laboratory for further analysis.
Finally, they close the surgical wound in a single layer and check for bleeding before ending the procedure.
