A rheumatology note documents osteoarthritis of the right knee and left hip with enough detail for site-specific coding. A multiple-sites OA option also exists in the classification. What is the preferred approach?
Select an answer to reveal the explanation.
Short Explanation
Specificity wins when the note hands it to you. Right knee and left hip OA aren’t a vague ‘multiple sites’ shrug if you can code each joint cleanly. Don’t crush clear sites into a blurrier bucket just to save keystrokes.
Full Explanation
ICD-10-CM favors the highest specificity supported by documentation. When osteoarthritis sites and laterality are documented, site-specific codes are generally preferred over a less specific multiple-sites or unspecified code. Multiple-sites options remain appropriate when documentation supports that pattern without usable site detail. Coders should not omit documented sites solely for convenience.
