A new set of codes was released for use beginning on Oct. 1, 2017. The category, H54, includes codes for blindness and low vision and with that brings many changes for documentation and coding.
In 2013 the World Health Organization (WHO) campaigned for greater clarity in the reporting of blindness and low vision and with this latest update we will be following those parameters. What that means for us is a potential change in documentation standards and understanding the category levels.
The definition of visual impairment and blindness contained the term “best Corrected Vision in the better eye. According to WHO, recent studies have shown that the use of “best corrected” vision overlooks large portions of visual impairments, including blindness, due to uncorrected refracted error. This is common occurrence in many parts of the world.
Uncorrected refractive error is now considered to be a major cause of visual impairment and estimations are under way to calculate the loss in terms of disability-adjusted life years (DALY) resulting from this cause.
In the new coding convention, the words “best corrected” is being replaced with the word “presenting.”
The new codes introduce categories. Documentation will need to include:
- Type
- Stage (category)
- Laterality
Categories are divided between mild or no visual impairment, moderate, severe and blindness.
| Category | Worse than: | Equal to or better than: |
| Mild or no visual impairment 0 |
6/18 3/10 (0.3) 20/70 |
|
| Moderate visual impairment 1 |
6/18 3/10 (0.3) 20/70 |
6/60 1/10 (0.1) 20/200 |
| Severe visual impairment 2 |
6/60 1/10 (0.1) 20/200 |
3/60 1/20 (0.5) 20/400 |
| Blindness 3 |
3/60 1/20 (0.5) 20/400 |
1/60* 1/50 (0.02) 5/300 (20/1200) |
| Blindness 4 |
1/60* 1/50 (0.02) 5/300 (20/1200) |
Light perception |
| Blindness 5 |
No light perception | No light perception |
| 9 | Undetermined or unspecified | Undetermined or unspecified |

H54.7 Unspecified visual loss
These codes could be confusing when first starting to use them due to the complexity of the combination codes. There is also a new guideline applicable as well.
If “blindness” or “low vision” of both eyes is documented but the visual impairment category is not documented, assign code H54.3, Unqualified visual loss, both eyes. If “blindness” or “low vision” in one eye is documented but the visual impairment category is not documented, assign a code from H54.6-, Unqualified visual loss, one eye. If “blindness” or “visual loss” is documented without any information about whether one or both eyes are affected, assign code H54.7, Unspecified visual loss.
This guideline is the new chapter specific guideline for the codes listed above. If the visual impairment category is not documented we are instructed to use the unspecified.
Always be cautious when using unspecified codes and be sure to check payer policies to avoid rejections.
