ICD-10: H54.42A3

The ICD-10 code H54.42A3 specifically refers to a clinical diagnosis of blindness in the left eye, categorized as "category 3," while the right eye maintains normal vision. This classification is part of the broader ICD-10-CM coding system, which is used for documenting and billing various health conditions.

Clinical Description

Definition of Blindness

In the context of ICD-10 coding, "blindness" is defined as a significant loss of vision that cannot be corrected with standard glasses or contact lenses. The classification of blindness is often based on visual acuity measurements, with "category 3" indicating a specific level of visual impairment.

Category 3 Blindness

Category 3 blindness typically refers to a visual acuity of less than 20/200 in the affected eye (in this case, the left eye) or a visual field that is severely restricted. This level of impairment significantly impacts daily activities and quality of life, necessitating appropriate medical and rehabilitative interventions.

Normal Vision in the Right Eye

The designation of "normal vision" in the right eye indicates that the individual has no significant visual impairment in that eye. This distinction is crucial for treatment planning and rehabilitation, as it allows for the potential use of the right eye for visual tasks, while the left eye's blindness requires specific accommodations.
