Clinical Information

• Iridocyclitis

  acute or chronic inflammation of the iris and ciliary body characterized by exudates into the anterior chamber, discoloration of the iris, and constricted, sluggish pupil. symptoms include radiating pain, photophobia, lacrimation, and interference with vision.

• Ophthalmia, Sympathetic

  granulomatous uveitis which follows in one eye after a penetrating injury to the other eye; the secondarily affected eye is called the sympathizing eye, and the injured eye is called the exciting or activating eye.

• Uveitis

  inflammation of part or all of the uvea, the middle (vascular) tunic of the eye, and commonly involving the other tunics (sclera and cornea, and the retina). (dorland, 27th ed)

• Uveitis, Anterior

  inflammation of the anterior uvea comprising the iris, angle structures, and the ciliary body. manifestations of this disorder include ciliary injection, exudation into the anterior chamber, iris changes, and adhesions between the iris and lens (posterior synechiae). intraocular pressure may be increased or reduced.

• Uveitis, Intermediate

  inflammation of the pars plana, ciliary body, and adjacent structures.

• Uveitis, Posterior

  inflammation of the choroid as well as the retina and vitreous body. some form of visual disturbance is usually present. the most important characteristics of posterior uveitis are vitreous opacities, choroiditis, and chorioretinitis.

• Uveitis, Suppurative

  intraocular infection caused mainly by pus-producing bacteria and rarely by fungi. the infection may be caused by an injury or surgical wound (exogenous) or by endogenous septic emboli in such diseases as bacterial endocarditis or meningococcemia.

• Pars Planitis

  form of granulomatous uveitis occurring in the region of the pars plana. this disorder is a common condition with no detectable focal pathology. it causes fibrovascular proliferation at the inferior ora serrata.

• Iritis

  inflammation of the iris characterized by circumcorneal injection, aqueous flare, keratotic precipitates, and constricted and sluggish pupil along with discoloration of the iris.

• Chronic Iridocyclitis|Chronic Uveitis

  uveitis that is usually insidious in onset, bilateral, and can be asymptomatic, most often affecting the anterior uveal tract, including the iris and ciliary body, and can result in long-term complications. it is most commonly associated with certain forms of juvenile idiopathic arthritis, but may occur independent of arthritis.

• Iridocyclitis

  inflammation of the iris and the ciliary body.

• Acute Anterior Uveitis

  sudden onset of anterior uveitis, usually unilateral, and associated with pain, erythema, photophobia, and blurred vision. often associated with hla-b27, with or without co-existing spondyloarthritis.

• Anterior Uveitis

  inflammation of the iris and anterior chamber of the eye.

• CDAI Version 1 - Iritis/Uveitis|CDAI01-Iritis/Uveitis|CDAI01-Iritis/Uveitis|CDAI0110

  crohn's disease activity index version 1 (cdai version 1) iritis/uveitis.

• Grade 1 Uveitis, CTCAE|Grade 1 Uveitis|Grade 1 Uveitis

  anterior uveitis with trace cells

• Grade 2 Uveitis, CTCAE|Grade 2 Uveitis|Grade 2 Uveitis

  anterior uveitis with 1+ or 2+ cells

• Grade 3 Uveitis, CTCAE|Grade 3 Uveitis|Grade 3 Uveitis

  anterior uveitis with 3+ or greater cells; intermediate posterior or pan-uveitis

• Grade 4 Uveitis, CTCAE|Grade 4 Uveitis|Grade 4 Uveitis

  best corrected visual acuity of 20/200 or worse in the affected eye

• HBI - Complication: Uveitis|HBI01-Complication: Uveitis|HBI01-Complication: Uveitis|HBI0105B

  harvey-bradshaw index (hbi) complication: uveitis.

• Intermediate Uveitis|Pars Planitis

  inflammation of the pars plana.

• Panuveitis

  a disorder characterized by inflammation of the entire uvea which includes the iris, ciliary body, and choroid. causes include systemic infections, sarcoidosis, and cancers.

• Posterior Uveitis|Choroiditis

  an inflammatory process that affects the choroid.

• Tubulointerstitial Nephritis and Uveitis|TINU

  an autoimmune disorder comprising tubulointerstitial nephritis and uveitis.

• Uveitis

  an inflammatory process affecting a part of or the entire uvea. causes include inflammatory agents (e.g., herpes simplex, herpes zoster, leptospirosis) and systemic diseases (e.g., inflammatory bowel disease, multiple sclerosis, systemic lupus erythematosus, ankylosing spondylitis). patients present with pain and redness in the eye, light sensitivity, and blurred and decreased vision.

• Uveitis Glaucoma and Hyphema Syndrome|UGH (Uveitis Glaucoma Hyphema) Syndrome

  clinical triad of uveitis, glaucoma, and hyphema (ugh), especially associated with the early anterior chamber intraocular lens (iol). glaucoma is believed to be caused by movement of the iol against the iris causing release of inflammatory and red blood cell debris, which obstruct the trabecular meshwork. the haptic also may cause direct damage to the trabecular meshwork contributing to the glaucoma. incidence of ugh is dependent on both surgical methodology applied in the cataract population and type of iol used. ugh is particularly common if metal clip lenses have been used. components of the condition may be reversed if the offending iol is removed before permanent damage has occurred.

• Uveitis, CTCAE|Uveitis|Uveitis|Uveitis

  a disorder characterized by inflammation to the uvea of the eye.

• Cyclitis

  inflammation of the ciliary body.

• Pars Planitis

  an inflammatory disorder of the cilliary body in the uvea that affects healthy, younger individuals who are often asymptomatic. it has a long clinical course with relapses and remissions. symptoms include mildly decreased vision and floaters. it may be associated with autoimmune disorders.

• Iritis

  inflammation of the iris.

H20.9 is grouped with Diagnostic Related Groups - MS-DRG Mapping

Diagnostic Related Groups (DRGs) are a classification system used to group together diagnosis codes for the purpose of reimbursement and healthcare management. DRGs are used to standardize the way hospitals and other providers are paid for inpatient services. In this system patients are grouped together based on their principal diagnosis in areas referred to as Major Diagnostic Categories (MDC). Once a patient is assigned a particular diagnostic category, providers receive a predetermined payment rate for the services rendered. This reimbursement rate is often fixed and is meant to cover the cost of care for that patient. Reimbursement is also affected by the relative weight of a diagnostic related group based on the severity of a patient's illness and the associated cost of care during hospitalization.

Diagnostic related groups encourage healthcare providers to focus on quality and efficiency in patient care while managing costs effectively. The diagnosis code is present in the following groups for version MS-DRG V41.0 applicable from 10/01/2023 through 09/30/2024.

MS-DRG	MS-DRG Title	MCD	Relative Weight
124	OTHER DISORDERS OF THE EYE WITH MCC OR THROMBOLYTIC AGENT	02	1.3219
125	OTHER DISORDERS OF THE EYE WITHOUT MCC	02	0.7975

The relative weight of a diagnostic related group determines the reimbursement rate based on the severity of a patient's illness and the associated cost of care during hospitalization.

Convert H20.9 to ICD-9-CM

• ICD-9-CM Code: 364.3 - Iridocyclitis NOS
  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.

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.
