What This Code Means

A genetic condition where the body produces little to no melanin affecting skin, hair, and eyes, but whether the enzyme deficiency is complete or partial is not specified.

Coding Tips

• •This is the least specific oculocutaneous albinism code; attempt to determine tyrosinase status from clinical documentation
• •Document all skin and eye manifestations to support medical necessity

Clinical Significance

Oculocutaneous albinism, unspecified, indicates confirmed albinism affecting both skin and eyes where the specific subtype (tyrosinase-negative, tyrosinase-positive, or other) has not been determined. This code reflects either incomplete genetic evaluation or cases where the clinical presentation does not clearly differentiate between subtypes. These patients still require dermatologic surveillance and ophthalmologic management.

Documentation Requirements

• ✓Documentation should include clinical findings demonstrating reduced pigmentation in both skin/hair and eyes, ophthalmologic examination results, and the reason the specific type cannot be determined.
• ✓If genetic testing is planned, document the referral.
• ✓Visual acuity, nystagmus assessment, iris transillumination, and skin examination findings should be detailed.
• ✓Sun protection counseling and cancer screening frequency should be noted.
