What This Code Means
E53.8 is the ICD-10-CM diagnosis code for deficiency of other specified b group vitamins. This code represents deficiency of other B vitamins not specifically listed, such as biotin, pantothenic acid, or folate deficiency. E53.8 sits in the ICD-10-CM chapter for endocrine, nutritional and metabolic diseases (e00-e89), within the section covering other nutritional deficiencies (e50-e64).
E53.8 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.
Specify which B vitamin is deficient in the documentation for clarity.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for E53.8 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Specify which B vitamin is deficient in the documentation for clarity
- •Note that folate and B12 deficiencies have their own specific codes (E53.2 and E53.8 respectively); verify correct code selection
Excludes 1, Do NOT code together
- folate deficiency anemia (D52.-)
Excludes 2, Not included here, may code separately
- vitamin B12 deficiency anemia (D51.-)
