Use when GGO is confirmed to be due to COVID-19.

Documentation & Coding Risks

Avoid these common issues when documenting Ground Glass Opacity.

Documenting GGO without specifying laterality or distribution.

Impact

Clinical: May lead to inadequate treatment planning., Regulatory: Non-compliance with documentation standards., Financial: Potential for claim denials.

Mitigation

Always include laterality and distribution in documentation., Use structured templates for imaging findings.

Coding R91.8 without specifying the underlying cause.

Impact

Reimbursement: May lead to claim denials or reduced reimbursement., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate representation of patient condition.

Mitigation

Always code the underlying condition first if known.

Incorrect sequencing of codes

Impact

Failure to sequence the underlying condition before R91.8.

Mitigation

Educate coders on proper sequencing rules.
