Hallux Valgus ICD-10-CM Codes

What hallux valgus ICD codes can I use?

Hallux Valgus, commonly known as a bunion, is a foot deformity where 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.

Here are six hallux valgus ICD codes. Three of them are specific to hallux valgus, while the latter three are related to it:

1. 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 of the Hallux Valgus hasn’t been determined, you can use this ICD code.

2. 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.

3. M20.12 - Hallux valgus (acquired), left foot

This is similar to Item 2, but it’s meant to be used only if the Hallux Vagus is confirmed to be on the left foot.

4. Q66.219 - Congenital metatarsus primus varus, unspecified foot

This ICD-10 code is meant to be used on a patient confirmed to have congenital metatarsus primus varus, a foot deformity characterized by the first metatarsal bone deviating away from the second metatarsal. It is usually rotated away. In the case of this ICD code, the specific foot is unspecified. This foot deformity is commonly associated with Hallux Valgus.

5. Q66.211 - Congenital metatarsus primus varus, right foot

This is similar to Item 4, but it’s meant to be used only if the Congenital Metatarsus Primus Varus is confirmed to be on the right foot.

6. Q66.212 - Congenital metatarsus primus varus, left foot

This is similar to Item 4, but it’s meant to be used only if the Congenital Metatarsus Primus Varus is confirmed to be on the left foot.

Are these hallux valgus ICD codes are billable?

Yes. All of the aforementioned hallux valgus-related ICD-10 codes are valid and billable.

Clinical information about hallux valgus:

As previously mentioned, hallux valgus, commonly as bunions, is a foot deformity caused by prolonged pressure on the big toe joint. This misalignment of the joint results in the formation of a noticeable bump.

To determine if you have a bunion or are at risk of developing one, watch out for these indicators:

• Difficulty or inability to bend your big toe.
• Experience pain and a burning sensation when attempting to bend your big toe.
• Numbness in the big toe.
• Calluses on the big toe.
• Presence of hammertoes, characterized by tight tendons and joints in the toes.

These signs can help you identify the presence of a bunion or assess your susceptibility to developing one.

Synonyms include:

• Acquired hallux valgus
• Bunion
• Hallux valgus due to metatarsus primus varus
• Hallux valgus interphalangeus
• Valgus deformity of lesser toe
• Valgus deformity of toe
