Vitamin D deficiency is a common health concern that can lead to various health issues, including bone disorders and a weakened immune system. In the medical field, diagnostic codes are used to classify and identify specific conditions for record-keeping and billing purposes. In this article, we'll delve into the icd 10 for vitamin d deficiency associated with vitamin D deficiency, providing an understanding of how healthcare professionals use these codes to accurately document and manage patients' conditions.

What is ICD-10?

ICD-10 stands for the International Classification of Diseases, 10th Revision. It is a standardised system developed by the World Health Organization (WHO) for classifying diseases, disorders, and other health-related conditions. The ICD-10 coding system is widely used by healthcare providers, insurance companies, and other healthcare entities for various purposes, including diagnosis documentation, billing, and statistical analysis.

ICD-10 Codes for Vitamin D Deficiency:

Vitamin D deficiency is categorised within the ICD-10 coding system under the code category "E55," which specifically addresses nutritional deficiencies. Here are some of the ICD-10 codes associated with vitamin D deficiency:

E55.0 - Rickets, active: This code is used when a patient is diagnosed with active rickets due to vitamin D deficiency. Rickets is a condition that affects bone development and can result in weakened and deformed bones.

E55.1 - Rickets, late effect: If a patient has a history of rickets due to vitamin D deficiency and is now experiencing the long-term effects of the condition, this code is used.

E55.9 - Vitamin D deficiency, unspecified: This code is used when a healthcare provider diagnoses a patient with vitamin D deficiency but does not specify whether it has led to rickets or any other specific condition.

Z87.310 - Personal history of rickets: When a patient has a history of rickets due to vitamin D deficiency, this code is used to indicate their personal medical history.

Z91.82 - Personal history of vitamin D deficiency: This code is used when a patient has a personal history of vitamin D deficiency but is not currently experiencing the condition.

Usage and Importance of ICD-10 Codes:

ICD-10 codes play a crucial role in the healthcare system for various reasons:

Accurate Documentation: ICD-10 codes ensure accurate and standardized documentation of patient conditions, allowing healthcare providers to communicate effectively with other medical professionals and insurance companies.

Billing and Reimbursement: Medical coding, including ICD-10 codes, is essential for accurate billing and reimbursement processes. Insurance companies use these codes to determine the appropriate reimbursement for medical services provided.

Research and Analysis: The use of ICD-10 codes allows for systematic tracking and analysis of various health conditions, aiding researchers and policymakers in understanding disease patterns and making informed decisions.

Healthcare Statistics: ICD-10 codes contribute to the compilation of healthcare statistics at local, national, and global levels. These statistics help identify health trends, allocate resources, and develop public health strategies.

Diagnostic Process for Vitamin D Deficiency:

When diagnosing vitamin D deficiency, healthcare providers typically follow a process that includes:

Clinical Evaluation: Healthcare professionals review the patient's medical history, symptoms, and risk factors for vitamin D deficiency. Symptoms may include bone pain, muscle weakness, fatigue, and increased susceptibility to infections.

Laboratory Testing: Blood tests, such as measuring the levels of 25-hydroxyvitamin D (25(OH)D), are used to assess the patient's vitamin D status. These tests help confirm the diagnosis and determine the severity of the deficiency.

Physical Examination: In cases where rickets or other bone-related conditions are suspected, a physical examination may reveal bone deformities or abnormalities.

Diagnostic Coding: Based on the clinical evaluation and test results, the healthcare provider assigns the appropriate ICD-10 code to accurately document the patient's condition.


ICD-10 codes play a significant role in the healthcare field by providing standardised codes for various health conditions, including vitamin D deficiency. These codes ensure accurate documentation, billing, research, and analysis. If you suspect you have a vitamin D deficiency or are experiencing symptoms related to it, it's important to consult a healthcare professional. A medical provider will conduct the necessary evaluations and tests to diagnose the condition and assign the appropriate ICD-10 code if necessary. Accurate diagnosis and proper management of vitamin D deficiency can lead to improved health and well-being.
