ICD-10 Code H05.243 – Constant exophthalmos, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H05.243 – Constant exophthalmos, bilateral
What it is
H05.243 identifies constant protrusion of both eyes. Use it when the record documents bilateral exophthalmos that is persistent rather than intermittent or episodic.
Clinical signs
Typical findings include forward displacement of both globes and a prominent eye appearance. Clinical features vary; refer to documentation for cause, chronicity, and whether the protrusion is truly constant.
When to use this code
Use this code when the clinician specifically documents constant bilateral exophthalmos, proptosis, or similar wording for both eyes. It may appear in eye, endocrine, or orbital evaluations. If the laterality or persistence is unclear, check documentation before coding.
Do not use for
Do not use it for unilateral exophthalmos or for intermittent eye prominence unless the chart states constant bilateral involvement. Do not assume the cause is thyroid disease without documentation.
Coding tip
Match the code to both laterality and chronicity; if either is missing, query the provider.
