How to Code Thyroid Eye Disease (TED) with New ICD-10-CM Codes
New ICD-10-CM diagnosis codes are now available to capture thyroid eye disease (TED) with greater specificity. These codes improve the ability to identify affected patients, support clinical tracking, and strengthen documentation for research, quality reporting, and patient outcomes.
What Is Thyroid Eye Disease (TED)?
Thyroid eye disease is an autoimmune inflammatory condition affecting the tissues around the eyes. Common features include:
- Bulging eyes (proptosis)
- Pain or pressure
- Dryness or irritation
- Swelling of the eyelids
- Possible vision changes
TED is most commonly associated with Graves’ disease (hyperthyroidism) but may also occur with:
- Hashimoto’s thyroiditis
- Hypothyroidism
- Euthyroid states
New ICD-10-CM Codes for Thyroid Eye Disease
New ICD-10-CM Codes for Thyroid Eye Disease
These codes allow documentation of laterality, improving accuracy and supporting medical necessity for treatment:
| Code | Description |
|---|---|
| H05.831 | Thyroid orbitopathy, right orbit |
| H05.832 | Thyroid orbitopathy, left orbit |
| H05.833 | Thyroid orbitopathy, bilateral |
| H05.839 | Thyroid orbitopathy, unspecified orbit |
Treatment Considerations for Thyroid Eye Disease
These codes may be used to support medical necessity for treatments such as:
- Teprotumumab (Tepezza) – the first FDA-approved therapy specifically for TED
- Corticosteroids for inflammation control
- Radiation therapy in more severe or refractory cases
Coding Example & Reminder for Thyroid Eye Disease
***Reminder: Don’t Forget Associated Thyroid Diagnoses. Always code the underlying thyroid condition to provide a complete clinical picture and support medical necessity.
Coding Example
Final diagnosis: Graves’ disease with thyroid eye disease affecting both eyes.
Codes:
- H05.833 – Thyroid orbitopathy, bilateral
- E05.00 – Hyperthyroidism with goiter
