What Blurry Vision ICD Codes Can I Use?

If you’re looking for Blurry Vision ICD codes, none specify blurry vision in their names. What you need to look for are ICD-10 codes that are specific to certain ailments characterized by blurry vision, such as astigmatism and retinopathy. Here are examples of such ICD-10 codes that you can use:

  1. H52.229 - Regular astigmatism, unspecified eye

This ICD-10 code is meant to be used on a patient confirmed to have Regular Astigmatism. Astigmatism is a common eye condition characterized by an eye with an abnormal curvature. This curve can result in blurred vision.

This code should only be used if it’s not confirmed which eye has the Astigmatism. Once the affected eye is identified, please use a more specific ICD-10 code from Items 2 to 4.

  1. H52.221 - Regular astigmatism, right eye

This is the same as Item 1, but it’s meant for the left eye this time.

  1. H52.222 - Regular astigmatism, left eye

This is the same as Item 1, but it’s meant for the right eye this time.

  1. H52.223 - Regular astigmatism, bilateral

This is the same as Item 1, but it’s meant to be used on patients confirmed to have Regular Astigmatism in both eyes.

  1. H35.039 - Hypertensive retinopathy, unspecified eye

This ICD-10 code is meant to be used on a patient confirmed to have Hypertensive Retinopathy. Retinopathy is the term used to refer to the damage of the retina’s blood vessels. This is the leading cause of preventable blindness. In the case of this ICD-10 code, Retinopathy is caused by hypertension. Having a blurred vision is a symptom of Retinopathy.

Like Item 1, this should only be used when the affected eye hasn’t been identified. Once the affected eye is identified, please use a more specific code between Items 6 and 8.

  1. H35.031 - Hypertensive retinopathy, right eye

This is the same as item 5, but it’s meant for the right eye this time.

  1. H35.032 - Hypertensive retinopathy, left eye

This is the same as item 5, but it’s meant for the left eye this time.

  1. H35.033 - Hypertensive retinopathy, bilateral

This is the same as item 5, but it’s meant to be used on patients confirmed to have Hypertensive Retinopathy in both eyes.

Are These Blurry Vision ICD Codes Billable?

Yes. These Blurry Vision-related ICD-10 codes are valid and billable.

Clinical Information

Blurry Vision is the most common eye problem people complain to eye doctors. When a person has blurred vision, it means that their vision isn’t sharp or only clear up to a specific range.

Certain deformities in the eyes can cause this. One example is Astigmatism, which we mentioned earlier.

Certain conditions can also cause blurred vision that progresses over time. An example of a basic condition that can cause blurred vision is hypertension (hence the examples above). This can be treated by addressing hypertension. However, damage can accumulate over time so that the blurry vision can last.

More severe problems like Diabetes and Lupus can cause blurry vision, too. Getting injured, especially if the injury is in the head, can cause blurry vision.

Synonyms include:

  • Regular astigmatism
  • Regular astigmatism of the right eye
  • Regular astigmatism of the left eye
  • Bilateral eye astigmatism
  • Bilateral regular astigmatism
  • Hypertension with a disorder of the right retina
  • Hypertension with a disorder of the left retina
  • Bilateral hypertension with disorder of the retinas
  • Hypertensive retinopathy

Commonly asked questions

If blurry vision is caused by a refractive problem like Astigmatism, Farsightedness, or Nearsightedness, wearing eyeglasses, putting on contact lenses, or getting eye surgery can correct it.

Examples of problems that can cause blurry vision to occur out of the blue include having a stroke, sustaining a concussion, the detachment of the retina, an eye infection, an eye injury, and something as simple as a migraine.

Blurry Vision is commonly used to refer to vision that is out of focus. Cloud vision means you can’t see clearly because it feels like you’re looking through a cloud, fog, or haze. Even adjusting your focus won’t do anything if your vision is cloudy.
