ICD-10: H54.42A5

The ICD-10 code H54.42A5 specifically refers to a clinical diagnosis of blindness in the left eye categorized as "category 5," while the right eye maintains normal vision. This classification is part of the broader ICD-10-CM (International Classification of Diseases, 10th Revision, Clinical Modification) 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, which assess the clarity or sharpness of vision.

Category 5 Blindness

Category 5 blindness indicates a profound level of visual impairment. According to the ICD-10 guidelines, this category typically includes individuals who have a visual acuity of less than 20/400 in the affected eye, or a visual field of less than 10 degrees. This level of impairment significantly impacts daily activities and quality of life, necessitating specialized support and rehabilitation services.

Normal Vision in the Right Eye

The specification of "normal vision" in the right eye indicates that the individual retains full visual function in that eye. Normal vision is generally defined as having a visual acuity of 20/20 or better, which allows for the performance of most daily tasks without visual aids.

Implications for Patient Care

Diagnosis and Management

Patients diagnosed with H54.42A5 may require a comprehensive management plan that includes:
- Ophthalmological Evaluation: Regular assessments by an eye care professional to monitor the condition of the left eye and ensure the right eye remains healthy.
