Question: If a patient suffers from effusion of the same ankle and foot, should I submit two ICD-10 codes? Or is there a combination code for this diagnosis? Texas Subscriber Answer: You should report two codes, but it can be a bit confusing due to the parent code’s descriptor. The parent code for both conditions is M25.47- (Effusion, ankle and foot). From there, the parent code splits into these options: So, let’s say a patient suffers from right ankle and foot effusion. On the claim, you’d report M25.471 and M25.474.
