Documentation & Coding Risks

Avoid these common issues when documenting Lacunar Infarct.

Documenting 'stroke' without specifics

Impact

Clinical: Leads to unspecified diagnosis, Regulatory: Non-compliance with documentation standards, Financial: Potential for lower reimbursement

Mitigation

Ensure detailed documentation of imaging and clinical findings

Using I63.9 when 'lacunar' is documented

Impact

Reimbursement: Incorrect coding may lead to lower reimbursement, Compliance: Non-compliance with coding guidelines, Data Quality: Inaccurate clinical data representation

Mitigation

Always code I63.81 for confirmed lacunar infarct

Imaging confirmation

Impact

Coding without imaging confirmation may trigger audits

Mitigation

Ensure all lacunar infarcts are confirmed by imaging
