Code Classification

  • Diseases of the eye and adnexa
    (H00–H59)
    • Disorders of choroid and retina
      (H30-H36)
      • Other disorders of choroid
        (H31)

H31.1 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of choroidal degeneration. The code is not specific and is NOT valid for the year 2024 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

Specific Coding Applicable to Choroidal degeneration

Non-specific codes like H31.1 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10-CM codes with a higher level of specificity when coding for choroidal degeneration:

  • H31.10 for Unspecified choroidal degeneration - NON-BILLABLE CODE

  • Use H31.101 for Choroidal degeneration, unspecified, right eye - BILLABLE CODE

  • Use H31.102 for Choroidal degeneration, unspecified, left eye - BILLABLE CODE

  • Use H31.103 for Choroidal degeneration, unspecified, bilateral - BILLABLE CODE

  • Use H31.109 for Choroidal degeneration, unspecified, unspecified eye - BILLABLE CODE

  • H31.11 for Age-related choroidal atrophy - NON-BILLABLE CODE

  • Use H31.111 for Age-related choroidal atrophy, right eye - BILLABLE CODE

  • Use H31.112 for Age-related choroidal atrophy, left eye - BILLABLE CODE

  • Use H31.113 for Age-related choroidal atrophy, bilateral - BILLABLE CODE

  • Use H31.119 for Age-related choroidal atrophy, unspecified eye - BILLABLE CODE

  • H31.12 for Diffuse secondary atrophy of choroid - NON-BILLABLE CODE

  • Use H31.121 for Diffuse secondary atrophy of choroid, right eye - BILLABLE CODE

  • Use H31.122 for Diffuse secondary atrophy of choroid, left eye - BILLABLE CODE

  • Use H31.123 for Diffuse secondary atrophy of choroid, bilateral - BILLABLE CODE

  • Use H31.129 for Diffuse secondary atrophy of choroid, unspecified eye - BILLABLE CODE

Tabular List of Diseases and Injuries

The following annotation back-references are applicable to this diagnosis code. The Tabular List of Diseases and Injuries is a list of ICD-10-CM codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more.


Type 2 Excludes

Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

Patient Education


Eye Diseases

Some eye problems are minor and don't last long. But some can lead to a permanent loss of vision.

Common eye problems include:

  • Refractive errors
  • Cataracts - clouded lenses
  • Optic nerve disorders, including glaucoma
  • Retinal disorders - problems with the nerve layer at the back of the eye
  • Macular degeneration - a disease that destroys sharp, central vision
  • Diabetic eye problems
  • Conjunctivitis - an infection also known as pink eye

Your best defense is to have regular checkups, because eye diseases do not always have symptoms. Early detection and treatment could prevent vision loss. See an eye care professional right away if you have a sudden change in vision, if everything looks dim, or if you see flashes of light. Other symptoms that need quick attention are pain, double vision, fluid coming from the eye, and inflammation.
