What are Vitamin D Deficiency ICD-10-CM Codes?

If your patient has a vitamin D deficiency, the appropriate ICD-10 code you can use is E55: Vitamin D deficiency. This falls under broader categories of vitamin deficiency and nutritional deficiencies, particularly those related to vitamin D levels and inadequate absorption of nutrients.

However, if you discovered that vitamin D is either a cause or symptom of what the patient is feeling, you can use the following Vitamin D Deficiency associated ICD Codes:

  • E55.9 - Vitamin D deficiency, unspecified: Used when clinical details (e.g., cause, type) are unavailable. It covers deficiency caused by insufficient dietary intake, inadequate skin production from sunlight, poor absorption, or abnormal metabolism of vitamin D. This may also relate to hereditary vitamin D-dependent conditions and deficiency sequelae when left untreated.
  • E55.0 - Rickets, active: This applies to pediatric cases of vitamin D deficiency. Rickets involves defective bone mineralization, leading to soft, weak bones and skeletal deformities. It is important for pediatric cases and requires more specific documentation than E55.9. This can be seen in vitamin D-dependent rickets or other forms of the disease.
  • M83.3 - Adult osteomalacia due to malnutrition: This code is used for adult osteomalacia, a softening of bones due to defective bone mineralization from vitamin D deficiency or malnutrition. It is not billable alone without more specific documentation in some coding systems, but relevant for detailed clinical records, especially in the presence of other vitamin deficiencies and nutritional conditions produced by insufficient vitamin intake.
  • E64.3 - Sequelae of rickets: This code covers long-term consequences or residual effects after rickets has been treated or resolved. It is used as a secondary code along with the primary diagnosis of rickets or vitamin D deficiency, often categorized under vitamin deficiency sequelae and other nutritional deficiencies.

E55 and M83 aren't valid for submission because they aren't specific enough. To add, one must use two diagnosis codes before using E64.3.

Which Vitamin D Deficiency ICD-10-CM Codes are billable? 

E55 (general vitamin D deficiency) and M83 (adult osteomalacia) lack specificity and are not billable. E64.3 requires two prior diagnosis codes for billing. For best results, always verify documentation supporting codes relating to vitamin deficiency or ICD-10 categorization protocols.

Clinical information

  • A patient usually has a Vitamin D deficiency condition if they don't include enough Vitamin D in the diet, their skin doesn't produce enough Vitamin D, their body can't absorb enough Vitamin D from their diet, or they cannot convert Vitamin D into a form that the body can metabolize. This also applies to cases of abnormal conversion, which may impact coagulation factor synthesis or bone metabolism.
  • If a patient doesn't have enough vitamin D, their body cannot absorb calcium, and their immune, nervous, and muscle systems are at risk of getting compromised. In addition, a deficiency can lead to the patient developing conditions and other ocular manifestations like osteoporosis and fractures and diseases like rickets in children and osteomalacia in adults. These may also include vitamin B deficiency, vitamin E deficiency, and rare cases of vitamin K deficiency, which affect different systems.
  • A patient is usually asked to take supplements to treat vitamin D deficiency. Additional evaluation may reveal overlapping issues such as unspecified niacin deficiency, metabolic diseases, corneal xerosis, vitamin impact, keratomalacia, vitamin damage, or even night blindness, depending on the underlying other B group or other vitamins vitamin deficiency causes.
  • Prevention of this condition is as simple as eating vitamin D-rich food in moderation, like fatty fish, cheese, mushrooms, egg yolks, milk, orange juice, soy drinks, dairy, etc. These efforts may help prevent insufficient production of vitamin-related hormones and reduce the risk of developing xerosis vitamin and other deficiency of vitamin complications.
