What is a ICD-10 Code?

ICD-10 (International Classification of Diseases, 10th Revision) codes are used to classify and code all diagnoses, symptoms, and procedures recorded in association with hospital care. These codes provide a standardized way to track health conditions and their treatment outcomes.

Detailed Description

This code indicates a deficiency in one or more B-group vitamins that are not covered by other specific deficiency codes. The B vitamin group includes several essential nutrients that help your body convert food into energy and maintain healthy nerve function. This particular code applies to deficiencies in B vitamins like biotin (B7), pantothenic acid (B5), or other less commonly deficient B vitamins. Symptoms may include fatigue, skin problems, hair loss, or neurological issues depending on which specific B vitamin is deficient.

Additional Information

Treatment typically involves vitamin supplementation and dietary modifications. Most B vitamin deficiencies respond well to treatment when identified early.
