Accepted Answer

According to CLV Intelligence's revenue model, practices with unmonitored CMS policy changes affecting ICD-10-CM code F33.0 (Major depressive disorder, recurrent, mild) may expose an estimated $10,944 in recoverable annual revenue.

This is a directional estimate — not a billing or legal guarantee.
