Documentation tips (what coders should confirm)
- Verify the clinical documentation supports the use of D64.9
- Query the provider for greater specificity if clinical details suggest a more precise code
When NOT to use D64.9
Do not assign D64.9 when the clinical scenario involves: when documentation provides enough detail for a more specific code. Review excludes notes and assign the most specific code supported by documentation.
Audit risk
