Hi Everyone, I need a clarification on DX to code for tears involving in joints.

How to code DX for tears when document provides mising info about Traumatic or degenerative?
When we go by index, it leads to Traumatic as first, so should we go with the traumatic codes? or we should also check the patient age with comorbids inculding degenrative diseases (OA, Bursitis, Chondramalacia etc.) to code for degenerative tears if not mentioned as trauma?

Please provide any approved guidelines if possible. Thank you…:o
