    ICD-10-CM Code For Vitamin D Deficiency: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group E55 includes diagnoses for vitamin D deficiency and related metabolic bone conditions such as osteomalacia and rickets caused by low levels of vitamin D. These ICD-10-CM diagnosis codes are used to document clinical presentations of vitamin D insufficiency, deficiency-related bone disease, and associated symptoms like muscle weakness or fractures, capturing severity and related complications. Accurate coding within the ICD-10-CM E55 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

    ICD-10-CM E55: Vitamin D Deficiency Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group E55 covers diagnoses related to inadequate vitamin D levels and associated clinical effects on bone and mineral metabolism. These conditions primarily affect the musculoskeletal system and metabolic processes, potentially causing osteomalacia, rickets, muscle weakness, and increased fracture risk. Accurate coding matters for correct claim processing and to reflect clinical complexity that influences care decisions and reimbursement.

    Use a code from this group when a clinical assessment or laboratory testing documents vitamin D insufficiency or deficiency leading to symptomatic or biochemical abnormalities. Select the specific code that reflects the documented severity, presence of complications like osteomalacia, or associated clinical manifestations.

    Typical Clinical Scenarios

    • An elderly patient with progressive proximal muscle weakness, diffuse bone pain, and a history of limited sun exposure presents to primary care for evaluation of falls and fatigue. Laboratory testing shows low serum 25-hydroxyvitamin D consistent with a symptomatic deficiency; the clinician assigns a vitamin D deficiency diagnosis to explain musculoskeletal symptoms and guide supplementation and follow-up. Typical codes: E55.9
    • A breastfeeding infant or toddler is brought to pediatric clinic for delayed growth and signs of rickets (widened wrists, bowing of legs) after a history of inadequate dietary vitamin D and minimal sunlight; radiographs confirm rickets changes and labs show markedly low 25-hydroxyvitamin D. The pediatrician documents vitamin D deficiency as the underlying nutritional cause of the child’s bone disease to direct treatment and monitoring. Typical codes: E55.0
    • A middle-aged patient with chronic malabsorption from celiac disease undergoing routine specialty follow-up is found to have persistently low vitamin D levels without acute symptoms; the deficiency is recorded as a comorbidity to address bone health and influence long-term management. Typical codes: E55.9
