About coding foot lightning
The ICD-10-CM code for foot lightning is E53.8 (Deficiency of other specified B group vitamins).
Within E53, choose E53.8 (Deficiency of other specified B group vitamins) only when documentation doesn't support a more specific option: Riboflavin deficiency (E53.0), Pyridoxine deficiency (E53.1) and vitamin B deficiency, unspecified (E53.9).
Don't report E53.8 together with the conditions in its Excludes1 note: folate deficiency anemia (D52.-).
The conditions in its Excludes2 note aren't part of E53.8, but may be coded alongside it if the patient has both: vitamin B12 deficiency anemia (D51.-).
Don't confuse with (Excludes1 for E53.8)
- folate deficiency anemia (D52.-)
