Impact
Reimbursement: May lead to incorrect reimbursement if intentional weight loss is miscoded., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate health records and data reporting.
Mitigation Strategy
Document and code for intentional weight loss separately, using appropriate codes like Z71.3 for counseling.
Impact
Inadequate documentation of weight loss percentage and timeframe.
Mitigation Strategy
