Mr. Waller reports a growing swelling present behind his left earlobe that has been increasing in size. He mentions pain and numbness on that side of his face. He gives a history of being an alcoholic for the past 20 years. Based on the clinical findings, the physician gives the diagnosis as a malignant neoplasm of the parotid gland. What is the correct ICD-10 code for his condition?
  1. CO7.F10
  2. C10.2
  3. C10.3
  4. C10.4
Explanation
Answer: A 

CO7.F10 is the correct code for this case because it codes for malignant neoplasm of the parotid gland. Additionally, as the patient has a history of alcohol dependence hence, F10 represents that part. 

Option B is not correct because C10.2 is used to code for malignant neoplasm of the lateral wall of the oropharynx. 

Option C is not correct because C10.3 is used to code for malignant neoplasm of posterior wall of oropharynx. 

Option D is not correct because C10.4 is used to code for malignant neoplasm of the branchial cleft.
