Medical Coding ICD-10

Category - 10,000 Series

A 60-year-old woman presents to her dermatologists office with a reddish brown lesion on her right upper arm. It is approximately 0.8 cm in diameter and is raised. The patient and provider decide to proceed with a shave excision and will send this to pathology for confirmation. The dermatologist suspects this is a benign angiofibroma. The patient receives local anesthetics at the site and the area is excised with a sharp razor. What is the correct code for this procedure?
  1. 11300
  2. 11301
  3. 11302
  4. 11305
Explanation
Answer: B - 11301 is correct because this lesion was removed by shaving. It is also 0.6 to 1.0 cm in diameter and is located on the arm.

Code 11300 is incorrect because this code is for 0.5 cm diameter lesions or smaller and this patient’s lesion is 0.8 cm. Code 11302 is incorrect because this code is used for longer than 1.1 cm to 2 cm diameter lesions. Code 11305 is incorrect because the lesion location is wrong for this code and it is longer than this code indicates.
