Decoding M25.572: Pain in Left Ankle and Foot Joints
M25.572 is a billable and specific code within the International Classification of Diseases, 10th Revision, Clinical Modification (ICD-10-CM) system. This means it’s a valid code for medical claims and accurately pinpoints a specific diagnosis.

This code falls under the broader category of M25.57, which denotes “Pain in ankle and joints of foot.” The digit “2” at the end of M25.572 specifies the left side of the body. Therefore, M25.572 is exclusively used when the pain is located in the patient’s left ankle and/or joints of the left foot.
Synonyms and Related Terms for M25.572
To further clarify the scope of M25.572, several approximate synonyms and related terms are associated with this diagnosis code:
- Left ankle joint pain
- Pain in left ankle
- Pain of left ankle joint
- Left ankle pain
- Sinus tarsi syndrome of left ankle
- Bilateral ankle joint pain (when both sides are affected, though M25.572 specifically points to the left)
- Bilateral foot joint pain (similarly, for bilateral cases, but M25.572 is left-specific)
- Bilateral sinus tarsi syndrome (again, for bilateral cases, M25.572 is left ankle focused)
