ICD-10-CM Code D31.1

Benign neoplasm of cornea

Version 2021 Non-Billable Code Neoplasm Benign

Not Valid for Submission

D31.1 is a "header" nonspecific and non-billable code code, consider using a code with a higher level of specificity for a diagnosis of benign neoplasm of cornea. The code is NOT valid for the year 2021 for the submission of HIPAA-covered transactions.

The following anatomical sites found in the Table of Neoplasms apply to this code given the correct histological behavior: Neoplasm, neoplastic cornea (limbus) or Neoplasm, neoplastic limbus of cornea .

ICD-10:D31.1
Short Description:Benign neoplasm of cornea
Long Description:Benign neoplasm of cornea

Consider the following ICD-10 codes with a higher level of specificity:

  • D31.10 - Benign neoplasm of unspecified cornea
  • D31.11 - Benign neoplasm of right cornea
  • D31.12 - Benign neoplasm of left cornea

Code Classification

  • Neoplasms (C00–D48)
    • Benign neoplasms, except benign neuroendocrine tumors (D10-D36)
      • Benign neoplasm of eye and adnexa (D31)

Code History

  • FY 2016 - New Code, effective from 10/1/2015 through 9/30/2016
    (First year ICD-10-CM implemented into the HIPAA code set)
  • FY 2017 - No Change, effective from 10/1/2016 through 9/30/2017

  • FY 2021 - No Change, effective from 10/1/2020 through 9/30/2021

Table of Neoplasms

The code D31.1 is included in the table of neoplasms by anatomical site. For each site there are six possible code numbers according to whether the neoplasm in question is malignant, benign, in situ, of uncertain behavior, or of unspecified nature. The description of the neoplasm will often indicate which of the six columns is appropriate.

Where such descriptors are not present, the remainder of the Index should be consulted where guidance is given to the appropriate column for each morphological (histological) variety listed. However, the guidance in the Index can be overridden if one of the descriptors mentioned above is present.

Information for Patients


Benign Tumors

Also called: Benign neoplasms, Noncancerous tumors

Tumors are abnormal growths in your body. They can be either benign or malignant. Benign tumors aren't cancer. Malignant ones are. Benign tumors grow only in one place. They cannot spread or invade other parts of your body. Even so, they can be dangerous if they press on vital organs, such as your brain.

Tumors are made up of extra cells. Normally, cells grow and divide to form new cells as your body needs them. When cells grow old, they die, and new cells take their place. Sometimes, this process goes wrong. New cells form when your body does not need them, and old cells do not die when they should. These extra cells can divide without stopping and may form tumor.

Treatment often involves surgery. Benign tumors usually don't grow back.

Corneal Disorders

Your cornea is the outermost layer of your eye. It is clear and shaped like a dome. The cornea helps to shield the rest of the eye from germs, dust, and other harmful matter. It also helps your eye to focus. If you wear contact lenses, they float on top of your corneas.

Problems with the cornea include

  • Refractive errors
  • Allergies
  • Infections
  • Injuries
  • Dystrophies - conditions in which parts of the cornea lose clarity due to a buildup of cloudy material

Treatments of corneal disorders include medicines, corneal transplantation, and corneal laser surgery.
