ICD-10 Code E83.32 – Hereditary vitamin D-dependent rickets (type 1) (type 2) (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E83.32 – Hereditary vitamin D-dependent rickets (type 1) (type 2)
What it is
This code identifies an inherited disorder of vitamin D metabolism that causes rickets. It applies to hereditary vitamin D-dependent rickets type 1 or type 2, which affect bone mineralization in children.
Clinical signs
Typical findings include bowed legs, delayed growth, bone pain, and other signs of rickets. Clinical features vary; refer to documentation for the specific hereditary type and supporting diagnosis.
When to use this code
Use E83.32 when the provider documents hereditary vitamin D-dependent rickets, including type 1 or type 2. Code it when the record clearly supports a genetic vitamin D metabolism disorder rather than nutritional deficiency.
Choose this code for confirmed diagnoses in outpatient, inpatient, or specialist notes. If the documentation only says “rickets” or is unclear about cause, check documentation before assigning this code.
Do not use for
Do not use this code for nutritional rickets, renal rickets, or unspecified bone disease. If the record does not identify a hereditary vitamin D-dependent form, select the more accurate documented diagnosis.
Coding tip
Confirm the hereditary type in the chart; if type 1 or type 2 is stated, E83.32 is appropriate.
