Wiki Help with ICD-10 code for knee arthroscopy

[tammy roach]

Patient was seen May of 2015 and was DX'd with CURRENT meniscus tear (836.0). Came back a year later and DX used is S83.231D. Knee scope was done in July 2016 (over a year later) and I used DX code
M23.231. Am I correct using this DX code or should I have used the CURRENT DX of S83.231A?? Thanks for any responses.
