ICD-10 Code H44.313 – Chalcosis, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H44.313 – Chalcosis, bilateral
What it is
H44.313 identifies chalcosis affecting both eyes. It means copper deposition in ocular tissues, usually after a retained copper-containing intraocular foreign body. Use it when the record clearly documents bilateral involvement.
Clinical signs
Findings may include ocular discoloration, inflammation, and visual disturbance. Clinical features vary; refer to documentation, especially for evidence of copper-related eye changes in each eye.
When to use this code
Use this code when the provider documents chalcosis in both eyes, or when the assessment clearly states bilateral ocular copper deposition. It is appropriate when the condition is confirmed and not merely suspected. Check documentation for laterality if only one eye is described.
Do not use for
Do not use this code for chalcosis in one eye or when the note only mentions a retained foreign body without chalcosis. Check documentation if the eye involvement is unspecified.
Coding tip
Verify bilateral eye involvement in the assessment or impression before assigning H44.313.
