Mitigation
Remove R19.7 as A09 already includes diarrhea.
Not updating from K52.9 to a specific code after lab results
Impact
Reimbursement: Potential underpayment if specific pathogen is not coded., Compliance: Failure to comply with specificity requirements., Data Quality: Loss of specificity in patient records.
Mitigation
Update to specific code like A08.11 if pathogen is identified.
Inaccurate coding of infectious vs. non-infectious gastroenteritis
Impact
High risk of audits if documentation does not clearly differentiate between infectious and non-infectious causes.
Mitigation
Ensure thorough documentation of clinical findings and lab results.
