What ICD-10 codes are used for hallux valgus?
Hallux valgus, commonly known as a bunion, is a foot deformity in which the first metatarsal deviates medially, causing the first metatarsal head to protrude and the hallux to deviate laterally (with or without rotation).
This condition affects the alignment of the foot and can cause discomfort or pain. It often develops in adulthood but, in certain cases, may be one of the many congenital deformities of the musculoskeletal system.
Here are two valgus ICD codes under the category disease of the musculoskeletal system and connective tissue you can use:
M20.10: Hallux valgus (acquired), unspecified foot
This ICD-10 code is meant to be used on a patient confirmed to have hallux valgus. If the specific location hasn't been determined, you can use this ICD code.
M20.11: Hallux valgus (acquired), right foot
This is similar to Item 1, but it's meant to be used only if the hallux valgus is confirmed to be on the right foot.
M20.12: Hallux valgus (acquired), left foot
This is similar to Item 2, but it's meant to be used only if the hallux valgus is confirmed to be on the left foot.
