An ED provider documents 'otitis media' without specifying right, left, or bilateral, and the ICD-10-CM index leads to laterality-specific codes. What is the correct coding action?

Short Explanation
Laterality is like labeling left and right shoes — if nobody wrote which ear, you do not guess. When the code set expects a side, missing side means you stay at the documented level or get clarification. Common patterns and encoder folklore are not documentation.
Full Explanation
Many ICD-10-CM diagnosis codes require laterality for a complete, valid code. Documentation that states only 'otitis media' without right, left, or bilateral does not support assigning a side-specific code. Coders may report a non-lateralized or unspecified code when that is what the classification and documentation support, or query for laterality when greater specificity is needed for accurate reporting. Assumptions based on epidemiology or encoder hints are not substitutes for documented side.
