Coded from your documentation
Certified coders assign CPT, ICD-10-CM and HCPCS Level II codes from what is actually in the note. Where the documentation does not support the level of service the encounter appears to be, the question comes back to the provider before the claim goes out rather than after a payer asks.
Modifiers and edit pairs
Modifier use is reviewed against NCCI procedure-to-procedure edits and unit limits. Modifier 25 and 59 are the two that attract the most payer scrutiny and the most bundling denials, so their use is deliberate and supportable rather than routine.
Feedback that reaches the provider
Patterns get reported back in plain language — which documentation elements are routinely missing, which service lines are consistently under-coded relative to the note. This is the part that changes next quarter, rather than just cleaning up last quarter.
