Alex, a 29-year-old, mentions a discharge from his lower gums for the past 3 weeks. There is also an opening at the lower back tooth gums where the discharge flows. Additionally, there is pain while chewing food. Based on the findings, the patient is diagnosed with periapical abscess with the sinus. What is the correct ICD-10 code for his condition?
  1. K04.2
  2. K04.3
  3. K04.6
  4. K04.7
Explanation
Answer: C 

K04.6 is the correct code for this case because it codes for a periapical abscess with the sinus which is the diagnosis in this patient. 

Option A is not correct because K04.2 is used to code for pulp degeneration. 

Option B is not correct because K04.3 is used to code for abnormal hard tissue formation in the pulp. 

Option D is not correct because K04.7 is used to code for periapical abscess without sinus.
