DRG and Code Reconciliation – CDI and HIM Coding

NIX Process CDI reviews and codes chart concurrently.

CDI queries opportunities as identified.

Final review is done at discharge prior to coding, for identification of any missed opportunities.

Coding notified if missed opportunity is identified and will impact DRG.

After discharge Coding reviews and codes chart.<br>

Coding notifies CDI if any missed opportunity is encountered or if further clarification is needed for existing documentation.

After chart is coded, CDI is notified of any mismatches.
CDI does secondary review to identify cause of mismatch.

CDI coding is either adjusted to match coder or mismatch is discussed between CDI and Coder.

If unable to reconcile, account is referred to physician advisor or corporate HIM.<br>
