Step-by-step explanation:
The student's question pertains to assigning the correct ICD-10-CM diagnosis code for juvenile rheumatoid arthritis, specifically affecting both ankles.
Since juvenile rheumatoid arthritis is a specific form of arthritis with its unique characteristics, you would use the ICD-10-CM code specifically designated for it. While I am not able to directly assign the ICD-10-CM code without having access to the most up-to-date medical coding resources, juvenile rheumatoid arthritis typically falls under the category of 'M08' in the ICD-10-CM coding system. However, to pinpoint the exact code, one would need to consider specifics such as the current ICD-10-CM manual and the particularities of the patient's condition, including the fact that it is affecting both ankles.
