Impact

Reimbursement: Incorrect coding may lead to denied claims., Compliance: Non-compliance with ICD-10 guidelines., Data Quality: Inaccurate data on neuropathy prevalence.

Mitigation

Use G60.9 for idiopathic small fiber neuropathy.

Using E11.40 instead of E11.42 for diabetic neuropathy

Impact

Reimbursement: Potential underpayment due to less specific coding., Compliance: Failure to meet specificity requirements., Data Quality: Misrepresentation of diabetic complications.

Mitigation

Specify 'polyneuropathy' in documentation to use E11.42.
