Confusing erythema multiforme major with Stevens-Johnson syndrome.
Impact
Reimbursement: Incorrect coding can lead to inappropriate DRG assignment., Compliance: May result in compliance issues during audits., Data Quality: Affects the accuracy of clinical data.
Mitigation
Differentiate based on mucosal involvement and percentage of epidermal detachment.

Impact
Failure to sequence drug reaction codes first can lead to audit findings.
Mitigation
Educate coders on proper sequencing rules.
