I'm having an issue with this specific Excludes 1 problem:
Why does a code appear in the Excludes 1 column of one code, but it's not true in the converse?
Can someone clear this up for me? Thank you.
- M20.4 (Other hammer toe(s), Acquired) shows Q66 (Congenital deformities of feet) in the Excludes 1; However, Q66 does not have the M20.4 codes in their Excludes 1.
Why does a code appear in the Excludes 1 column of one code, but it's not true in the converse?
Can someone clear this up for me? Thank you.
