What left ankle pain ICD codes can I use?
Here are some left ankle pain ICD codes that you can use:
- M25.572 - Pain in left ankle and joints of left foot
This ICD-10 code is meant to be used on a person confirmed to have pain in their left ankle and the joints of their left foot. This is the most specific code you can use for left ankle pain, specifically general pain.
- S96.912A - Strain of unspecified muscle and tendon at ankle and foot level, left foot, initial encounter
This ICD-10 code is meant to be used on a person confirmed to have a strain in an unspecified muscle and tendon somewhere in the ankle and foot, specifically their left foot. The initial encounter means that they’re currently receiving active treatment for it.
- S96.912D - Strain of unspecified muscle and tendon at ankle and foot level, left foot, subsequent encounter
This ICD-10 code is the same as Item 2, but this time, it’s meant for patients who are in the recovery phase and are still receiving routine care for the problem, hence the subsequent encounter.
- S96.912S - Strain of unspecified muscle and tendon at ankle and foot level, left foot, sequela
What sequela is can be summed up as the late effects of a specific problem (chronic or residual). Given this, this ICD-10 code should be accompanied by two other ICD-10 codes, one of which should designate the sequela’s nature, while the other should describe the sequela (meaning its effects). In the context of this ICD-10 code, these problems were caused by left ankle pain.
- T50.905A - Adverse effect of unspecified drugs, medicaments and biological substances, initial encounter
This ICD-10 code is meant to be used on a patient dealing with a specific problem caused by certain drugs. This has an initial encounter label on it. If you’re wondering what this has to do with left ankle pain, you can use it for any problems in the left ankle that are causing pain that came from certain drugs or medication, or biological substances.
- T50.905D - Adverse effect of unspecified drugs, medicaments and biological substances, subsequent encounter
Same as Item 5, but this time, there’s a subsequent encounter label.
- T50.905S - Adverse effect of unspecified drugs, medicaments and biological substances, sequela
Same as Item 5, but this time, there’s a sequela label.
