Alex, a 33-year-old patient, complains of severe pain that generally occurs when he brushes, drinks or eats something cold. On oral examination, a black spot is found that is present below the gums suggestive of root caries in a molar tooth. What is the correct ICD-10 code for this case?
  1. K02.5
  2. K02.9
  3. K02.6
  4. K02.7
Explanation
Answer: D 

K20.7 is the correct code for dental root caries. Alex had a history of pain while chewing and drinking that demonstrates caries and the presence below the gingiva clearly points to root caries as the root surface (below the gum line) is involved. 

Option A is not correct because K02.5 is used to code for dental caries on pit and fissure surfaces. 

Option B is not correct because K02.9 is used to code for dental caries that are unspecified 

Option C is not correct because K02.6 codes for dental caries on a smooth surface.
