ICD-10 Code E55.9

E55.9 is a billable/specific ICD-10-CM code used for "Vitamin D deficiency, unspecified." This code is included in the chapter on endocrine, nutritional, and metabolic diseases.

Detailed description of E55.9

The diagnosis coded as E55.9 refers to a nutritional condition produced by a deficiency of vitamin D in the diet, insufficient production of vitamin D in the skin, inadequate absorption of vitamin D from the diet, or abnormal conversion of vitamin D to its bioactive metabolites. It is manifested clinically as rickets in children and osteomalacia in adults. This code is used when a patient has been diagnosed with a vitamin D deficiency that has not been further specified by testing. Vitamin D is essential for bone health, and deficiency can lead to various skeletal disorders.

Symptoms commonly associated with E55.9

  • Bone pain and tenderness
  • Muscle weakness
  • Increased risk of fractures
  • Possible fatigue and general discomfort
  • E55.0: Rickets, active
  • E55.8: Other vitamin D deficiencies

Appropriate usage of E55.9 for billing

Appropriate testing should be performed to confirm Vitamin D deficiency. E55.9 should be employed when there is evidence of vitamin D deficiency, but the specific type or cause has not been fully investigated or documented.

Instructional guidelines for providers coding E55.9

It's important to document signs and symptoms that led to testing for vitamin D levels, as well as the outcomes of such tests if available, even if the exact type of deficiency isn't specified.

Common pitfalls in coding with E55.9

  • Utilizing E55.9 without sufficient clinical evidence supporting a deficiency diagnosis.
  • Failure to follow up and specify the type of deficiency if subsequent test results become available.
