What are Foot Pain ICD-10-CM Codes?
Foot pain can stem from various causes, including joint pain, structural deformities, soft tissue disorders, and chronic conditions. The ICD-10-CM diagnosis codes help healthcare providers document these conditions clearly for treatment and reimbursement purposes. Below is the 2025 updated list of foot pain ICD-10 codes, including related conditions involving the ankle, joints, heel, and toes.
Pain
These general codes are used for nonspecific foot pain and are some of the most frequently used ICD-10-CM diagnosis codes for foot-related symptoms:
- M79.671 – Pain in right foot
- M79.672 – Pain in left foot
- M79.673 – Pain in unspecified foot
If the pain in the foot also involves the ankle or joints, or is suspected to originate from a broader area like the lower leg, consider using:
- M25.571 – Pain in right ankle and joints of right foot
- M25.572 – Pain in left ankle and joints of left foot
- M25.579 – Pain in unspecified ankle and joints of foot
These codes are also useful for documenting arthralgia, joint pain, pain in the limb, or discomfort in the joints of the unspecified foot.
Bunion
Foot deformities, like bunions or claw-like toes, can lead to persistent pain and affect how shoes fit properly. Use the following ICD-10 codes:
- M21.611 – Bunion of right foot
- M21.612 – Bunion of left foot
- M21.619 – Bunion of unspecified foot
In severe cases, bunions may be accompanied by hammer toe or middle joint abnormalities in the toes, especially the left toe or unspecified toe.
Bone spurs or osteophytes
Bone spurs, or osteophytes, often develop in response to long-term joint stress or conditions like plantar fasciitis. These can cause significant heel pain or pain in the heel bone:
- M25.774 – Osteophyte, right foot
- M25.775 – Osteophyte, left foot
- M25.776 – Osteophyte, unspecified foot
For calcaneal spurs (heel spurs), use:
- M77.31 – Calcaneal spur, right foot
- M77.32 – Calcaneal spur, left foot
- M77.30 – Calcaneal spur, unspecified foot
These codes apply when the affected area involves the back of the heel or unusually high foot arch, often seen in foot conditions related to overuse or chronic low-impact trauma on the foot.
Corns and callouses
Hardened skin layers, such as corns and calluses, may lead to foot and toe pain, especially in patients wearing ill-fitting footwear or experiencing pressure points. The code used here is L84 – Corns and callouses.
This remains a valid ICD-10 code for 2025 and is often linked with other soft tissue disorders or foot pain complaints.
