Tips for accurate ICD-10 code lookup
- Search by clinical term first, then refine by specificity — start broad (e.g., "diabetes") and narrow down to the exact type and manifestation
- Check Excludes1 and Excludes2 notes before assigning a code to avoid invalid code combinations on the same claim
- Verify laterality (left, right, bilateral) when applicable — many musculoskeletal and ophthalmologic codes require a laterality designation
- Use the most specific code supported by documentation — unspecified codes should only be used when the medical record lacks sufficient detail
- Cross-reference with official coding guidelines for sequencing rules — code order matters for etiology/manifestation pairs and principal diagnosis selection

After finding your code, validate it against all 13 ICD-10 coding guidelines using our Code Auditor to catch sequencing errors, excludes conflicts, and specificity issues.
