0.000What This Code Means
A birth defect caused by iodine deficiency during pregnancy where the specific type or presentation is not clearly documented or specified.
Coding Tips
- •Use this code only when the specific type of congenital iodine-deficiency syndrome cannot be determined from documentation
- •Query the provider if more specific information about goiter presence or neurological manifestations is available
Clinical Significance
Congenital iodine-deficiency syndrome, unspecified, is used when a patient has documented congenital iodine-deficiency syndrome but the specific type (neurological, myxedematous, or mixed) has not been determined or documented. This is a less clinically informative code that should prompt further characterization of the patient's clinical presentation. The condition remains extremely rare in regions with adequate iodine supplementation.
Documentation Requirements
- ✓Minimum documentation requires a confirmed diagnosis of congenital iodine-deficiency syndrome.
- ✓However, the provider should be queried to specify the type (neurological, myxedematous, or mixed) based on the predominant clinical features.
- ✓History of iodine-deficient environment, thyroid function tests, and neurodevelopmental assessments should be documented to support type classification.
Commonly Confused Codes
E00.0-E00.2 are more specific codes for the neurological, myxedematous, and mixed types respectively and should be used when the type is documented.E03.9 (Hypothyroidism, unspecified) captures unspecified hypothyroidism without the congenital iodine-deficiency etiology.E01.8 (Other iodine-deficiency related thyroid disorders) captures acquired iodine-deficiency conditions.
