Coding Headache with Tonsillitis

Hi I need your input, I am currently coding ED charts. I encountered a physician documentation of headache (784.0) and tonsillitis (463) as final diagnoses. My initial thought was to code both but then I checked mayo clinic and merck manual online. Both include headache as a common symptom of tonsillitis.

Should I just code tonsillitis (463)?

Thank you
