Last updated: January 31, 2025

Documentation Requirements
- Document Clinical Activity Score (CAS) if available
- Note presence and severity of proptosis (exophthalmometer readings)
- Document any extraocular muscle involvement or restriction
- Note thyroid status (hyperthyroid, euthyroid, hypothyroid)
- Specify laterality of eye involvement
Common Coding Scenarios
Documentation:
"Bilateral thyroid eye disease with proptosis. Graves hyperthyroidism, on methimazole."
Code:
H06.23, E05.00 - Dysthyroid exophthalmos bilateral + Thyrotoxicosis with diffuse goiter
Rationale:
Code both the eye manifestation (H06.23) and the underlying thyroid condition (E05.00).
Documentation:
"Right eye thyroid eye disease. Patient currently euthyroid on levothyroxine after thyroidectomy."
Code:
H06.21, E89.0 - Dysthyroid exophthalmos right eye + Postprocedural hypothyroidism
Rationale:
TED can persist after treatment. Code the eye findings plus current thyroid status.
Frequently Asked Questions
Use H06.2x codes for the eye manifestation (H06.21 right, H06.22 left, H06.23 bilateral). Also code the underlying thyroid condition (typically E05.00 for Graves disease).
Yes. Code both H06.2x for dysthyroid exophthalmos and the appropriate thyroid code (E05.x for hyperthyroidism, E89.0 for post-surgical hypothyroidism, etc.).
Still code H06.2x for the eye disease. For thyroid status, code E89.0 (postprocedural hypothyroidism) if post-thyroidectomy, or the appropriate code for their current thyroid condition.
