Patient complains about right knee pain without any injury or falls. Our doctor's diagnosis is "complex lateral meniscus tear without signs of bone marrow edema". S83.281A is for current injury, M23.261 is due to old injury/tear, but patient has never had any injury before. What is the correct ICD-10 code that I should use?

Thanks for your question.
When we search the ICD-10 CM for complex lateral meniscus tear via index, it directs us to the tear à meniscusà lateral à complex, which suggests S83.271A.
Now since the patient has never had any injury before, we may consider this a new or current injury. Injury does not mean to be a physical or external injury. It may be an internal injury too. Tear of meniscus should be considered an internal injury here. So, we should code this as S83.271A (Complex tear of lateral meniscus, current injury, right knee, initial encounter).
Please feel free to write if you have any question.
