Documentation supports a fully specified ICD-10-CM diagnosis, but the coder stops at a truncated parent code that is not billable. What guideline concept is violated?
Select an answer to reveal the explanation.
Short Explanation
Stopping halfway through a code is like writing half an address—mail won’t land. If the note supports the full character string, take it all the way. Truncating a billable code early is a classic specificity miss.
Full Explanation
Official Guidelines require coding to the highest level of specificity supported by the medical record. Valid codes include all characters required by the Tabular List for that category. Truncating to a non-billable parent when a more complete code is supported is incorrect. Unspecified codes are reserved for when documentation does not support greater detail.
