Code Classification

  • Neoplasms
    • Benign neoplasms, except benign neuroendocrine tumors
      • Benign neoplasm of eye and adnexa

D31.32 is a billable diagnosis code used to specify a medical diagnosis of benign neoplasm of left choroid. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

The following anatomical sites found in the Table of Neoplasms reference the parent code D31.3 of the current diagnosis code given the correct histological behavior: Neoplasm, neoplastic choroid .

Approximate Synonyms

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

  • Benign neoplasm of left choroid
  • Benign neoplasm of left choroid
  • Benign neoplasm of right choroid
  • Bilateral benign neoplasm of choroid
  • Nevus of choroid
  • Nevus of choroid of left eye

Clinical Classification

Clinical Information

  • Choroid

    the thin, highly vascular membrane covering most of the posterior of the eye between the retina and sclera.
  • Choroid Diseases

    disorders of the choroid including hereditary choroidal diseases, neoplasms, and other abnormalities of the vascular layer of the uvea.
  • Choroid Hemorrhage

    hemorrhage from the vessels of the choroid.
  • Choroid Neoplasms

    tumors of the choroid; most common intraocular tumors are malignant melanomas of the choroid. these usually occur after puberty and increase in incidence with advancing age. most malignant melanomas of the uveal tract develop from benign melanomas (nevi).
  • Choroid Plexus

    a villous structure of tangled masses of blood vessels contained within the third, lateral, and fourth ventricles of the brain. it regulates part of the production and composition of cerebrospinal fluid.
  • Choroid Plexus Neoplasms

    benign or malignant tumors which arise from the choroid plexus of the ventricles of the brain. papillomas (see papilloma, choroid plexus) and carcinomas are the most common histologic subtypes, and tend to seed throughout the ventricular and subarachnoid spaces. clinical features include headaches, ataxia and alterations of consciousness, primarily resulting from associated hydrocephalus. (from devita et al., cancer: principles and practice of oncology, 5th ed, p2072; j neurosurg 1998 mar;88(3):521-8)
  • Choroidal Effusions

    finding of fluid accumulation between the choroid and the sclera.
  • Choroidal Neovascularization

    a pathological process consisting of the formation of new blood vessels in the choroid.
  • Choroideremia

    an x chromosome-linked abnormality characterized by atrophy of the choroid and degeneration of the retinal pigment epithelium causing night blindness.
  • Choroiditis

    inflammation of the choroid.
  • Multifocal Choroiditis

    a multifocal uveitis syndrome involving the retinal pigment epithelium and capillary layer of the choroid. it is characterized by chronic uveitis and multiple choroid lesions referred to as white dots, blurry vision, floaters, sensitivity to light, blind spots, and eye discomfort.
  • Papilloma, Choroid Plexus

    a usually benign neoplasm that arises from the cuboidal epithelium of the choroid plexus and takes the form of an enlarged choroid plexus, which may be associated with oversecretion of csf. the tumor usually presents in the first decade of life with signs of increased intracranial pressure including headaches; ataxia; diplopia; and alterations of mental status. in children it is most common in the lateral ventricles and in adults it tends to arise in the fourth ventricle. malignant transformation to choroid plexus carcinomas may rarely occur. (adams et al., principles of neurology, 6th ed, p667; devita et al., cancer: principles and practice of oncology, 5th ed, p2072)
  • Polypoidal Choroidal Vasculopathy

    a choroid neovascularization characterized by serosanguineous retinal pigment epithelial detachment and leakage of serous exudate sometimes associated with aneurysmal polypoidal lesions.
  • White Dot Syndromes

    a group of idiopathic multifocal posterior uveitis syndromes involving the choroid; retinal pigment epithelium; and retina. they are characterized by multiple lesions of hypoautofluorescent dots in the fundus oculi and reduced visual acuity. several entities including birdshot chorioretinopathy are hla-a antigens serotype a29 positive.

Convert D31.32 to ICD-9-CM

  • ICD-9-CM Code: 224.6 - Benign neoplasm choroid
    Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.

Table of Neoplasms

The parent code D31.3 of the current diagnosis code is referenced 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.

Neoplasm, neoplastic Malignant

Patient Education

Benign 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.

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.

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
