H20.00 Unspecified acute and subacute iridocyclitis

ICD10CM code

#### Name of the Condition
- Unspecified Acute and Subacute Iridocyclitis
- Also referred to as iritis or anterior uveitis when specifically involving inflammation in those areas.

#### Summary
Unspecified acute and subacute iridocyclitis is an inflammation of the iris and ciliary body within the eye. It presents suddenly over a period of days (acute) or weeks (subacute) and can lead to eye discomfort or vision problems if untreated.

#### Causes
The exact cause is often unknown. It may be associated with autoimmune disorders, infections, or trauma to the eye. In some cases, it might be idiopathic with no identifiable cause.

#### Risk Factors
- Autoimmune diseases (e.g., rheumatoid arthritis, ankylosing spondylitis)
- Previous episodes of iridocyclitis
- Eye trauma
- Certain infections (e.g., herpes simplex, tuberculosis)

#### Symptoms
- Eye redness
- Blurred vision
- Eye pain or discomfort
- Sensitivity to light (photophobia)
- Tearing

#### Diagnosis
- Comprehensive eye examination by an ophthalmologist
- Slit-lamp examination to observe inflammation
- In some cases, blood tests or imaging may be performed to rule out underlying systemic conditions.

#### Treatment Options
- Corticosteroid eye drops to reduce inflammation
- Dilating drops to alleviate pain and prevent iris adhesions
- Oral medications for severe cases
- Addressing any underlying systemic condition if identified

#### Prognosis and Follow-Up
- With timely treatment, most cases resolve with no permanent damage.
- Regular follow-up is crucial to monitor inflammation and adjust treatment.
- Chronic cases may require long-term management strategies.

#### Complications
- Cataracts or glaucoma due to prolonged inflammation or use of steroid medications
- Permanent vision impairment if untreated
- Synechiae (adhesion of parts of the eye) formation

#### Lifestyle & Prevention
- Protect eyes from trauma by using safety eyewear
- Manage underlying systemic diseases effectively
- Regular eye check-ups, especially if you have a history of uveitis

#### When to Seek Professional Help
- Sudden onset of eye pain, redness, or vision changes

#### Additional Resources
- American Academy of Ophthalmology (www.aao.org)
- Uveitis support groups and online communities

#### Tips for Medical Coders
- Ensure specificity since "unspecified" is used when detailed causation is not documented.
- Avoid generic coding errors by verifying the distinction from chronic iridocyclitis, which has separate coding.
