Ray, a 20-year-old female, wants a treatment for her skin picking problem. She repeatedly picks skin off her hands and lips such that the area is reddened. She had made several attempts to stop her habit but nothing has worked. The diagnosis of her condition is given as excoriation (skin-picking) disorder. What is the correct ICD-10 code for her condition?
  1. F42.2
  2. F42.3
  3. F42.4
  4. F42.8
Explanation
Answer: C 

F42.4 is the correct code for this case because it codes for excoriation (skin-picking) disorder which is the diagnosis for the habit in this patient. 

Option A is not correct because F42.2 is used to code for mixed obsessional thoughts and acts. 

Option B is not correct because F42.3 is used to code for hoarding disorder. 

Option D is not correct because F42.8 is used to code for other obsessive-compulsive disorders.
