ICD-10 Code E70.310 – X-linked ocular albinism (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E70.310 – X-linked ocular albinism
What it is
E70.310 identifies X-linked ocular albinism, an inherited disorder that mainly affects the eyes. It causes reduced pigment in ocular tissues and can impair visual development.
Clinical signs
Typical findings include decreased visual acuity, nystagmus, photophobia, and reduced iris or retinal pigment. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents X-linked ocular albinism, ocular albinism, or a confirmed X-linked pattern affecting the eyes. It is appropriate for encounters focused on visual impairment linked to this inherited condition. Check documentation if the record does not clearly specify the subtype.
Do not use for
Do not use this code for generalized albinism, isolated hypopigmentation, or unspecified visual disturbance without a documented diagnosis. Do not assume X-linked inheritance unless the record supports it.
Coding tip
Assign E70.310 only when the provider clearly documents the X-linked ocular form; otherwise, query for clarification.
