Type 2 Excludes
A type 2 excludes note represents "Not included here".

When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

About the A65–A69 Code Range
These spirochetal diseases include nonvenereal syphilis, yaws, pinta, relapsing fever, and infections such as Lyme disease. Relapsing fever causes repeated episodes of fever separated by periods without symptoms.
A65 identifies nonvenereal syphilis. A66 separates yaws by its lesions and other manifestations, including bone and joint lesions and latent disease. A67 separates pinta by whether its lesions are primary, intermediate, late, or mixed. A68 distinguishes louse-borne from tick-borne relapsing fever. A69 groups other spirochetal infections, including Lyme disease and necrotizing ulcerative stomatitis.
