Learn about Acute Conjunctivitis (Pink Eye) diagnosis, clinical documentation, and medical coding. Find information on Conjunctivitis symptoms, treatment, and ICD-10 codes for accurate healthcare records and billing. This resource helps medical professionals ensure proper documentation and coding for Pink Eye and Acute Conjunctivitis cases.
Inflammation of the conjunctiva (eye's outer membrane), causing redness and discomfort.
Redness, tearing, itching, burning, discharge, gritty feeling, swollen eyelids.
Viral or bacterial infections, allergies, irritants (smoke, dust, chlorine).

When to use each related code
| Description | When to use |
|---|---|
| Inflammation of the conjunctiva. | Use for red, itchy eyes with discharge. Consider bacterial, viral, or allergic causes. |
| Allergic reaction affecting the conjunctiva. | Use for itchy, watery eyes with a history of allergies. Often seasonal or triggered by specific allergens. |
| Viral infection of the conjunctiva. | Use for watery discharge, often with preauricular lymph node swelling. Highly contagious. |
Best-practice checklist
- ✓Acute Conjunctivitis (Pink Eye) diagnosis: Document laterality (e.g., right, left, bilateral).
- ✓Conjunctivitis diagnosis: Describe discharge characteristics (e.g., watery, mucoid, purulent).
- ✓Pink Eye diagnosis: Document symptom onset and duration.
- ✓Acute Conjunctivitis: Note any associated symptoms like preauricular lymphadenopathy, photophobia.
- ✓Conjunctivitis: If bacterial, document antibiotic prescribed and rationale.
Common pitfalls to avoid
Missing or incorrect laterality (right, left, bilateral) for Acute Conjunctivitis can lead to claim rejections or inaccurate data.
Coding 'Acute Conjunctivitis' without specifying the cause (viral, bacterial, allergic) may impact reimbursement and quality metrics.
Incorrectly coding other types of conjunctivitis (e.g., chronic, neonatal) as Acute Conjunctivitis can lead to coding errors.
Best-practice tips
- 01Hand hygiene: Wash frequently.
- 02Avoid touching eyes.
- 03Don't share personal items.
- 04Disinfect surfaces regularly.
- 05Consult physician for diagnosis, treatment (ICD-10 H10, SNOMED CT 32786002).

Ready-to-paste narrative
Patient presents with acute onset of conjunctivitis, also known as pink eye. Symptoms include ocular redness, itching, tearing, and a foreign body sensation. The patient reports bilateral conjunctival injection with mucopurulent discharge, primarily in the morning. No significant visual changes are reported. Differential diagnosis includes bacterial conjunctivitis, viral conjunctivitis, allergic conjunctivitis, and other inflammatory eye conditions. Based on clinical presentation and examination, the diagnosis of acute conjunctivitis is made. Treatment plan includes warm compresses, frequent hand hygiene, and over-the-counter artificial tears. Patient education provided regarding contagious nature of conjunctivitis and preventive measures. Follow-up scheduled in one week to assess response to treatment. ICD-10 code H10.9, unspecified conjunctivitis, will be used for billing and coding purposes. Patient advised to return if symptoms worsen or do not improve with current treatment regimen. Conjunctival cultures may be considered if the condition does not respond to initial therapy.
Common questions and answers
What are the most effective differential diagnosis strategies for distinguishing bacterial, viral, and allergic acute conjunctivitis in adults?+
Differentiating between bacterial, viral, and allergic acute conjunctivitis requires a thorough clinical assessment. Bacterial conjunctivitis typically presents with purulent discharge, often unilateral initially, and eyelid matting. Viral conjunctivitis is commonly associated with a watery discharge, often bilateral, and may accompany other viral symptoms like upper respiratory infection. Allergic conjunctivitis features intense itching, bilateral watery discharge, and often co-occurring allergic symptoms such as rhinitis or sneezing. Consider implementing a systematic approach to eye examination, including assessing the type and quantity of discharge, presence of preauricular lymphadenopathy (more common in viral), and patient history of allergies. Explore how PCR testing can confirm adenoviral conjunctivitis when the diagnosis is uncertain. For cases with severe inflammation or atypical presentations, consider referral to an ophthalmologist.
How do I manage acute conjunctivitis in a patient with contact lenses, considering both infection control and appropriate treatment?+
Managing acute conjunctivitis in contact lens wearers requires immediate cessation of lens wear to prevent further complications and facilitate healing. Thorough cleaning or disposal of the current lenses and case is crucial to minimize re-infection. Emphasize the importance of proper contact lens hygiene to patients. Treatment will vary depending on the etiology. Bacterial conjunctivitis often requires topical antibiotic drops or ointment. Viral conjunctivitis is typically self-limiting, focusing on supportive care like cool compresses and artificial tears. Allergic conjunctivitis benefits from topical antihistamines and mast cell stabilizers. Instruct patients not to resume lens wear until the infection fully resolves and symptoms subside. Learn more about the latest guidelines on contact lens care and conjunctivitis management to ensure optimal patient outcomes. Consider implementing patient education materials addressing proper lens hygiene and the risks associated with continued lens wear during an active infection.
When should I refer a patient with acute conjunctivitis to an ophthalmologist, considering red flags and potential complications like keratitis?+
While most cases of acute conjunctivitis are self-limiting or readily managed in primary care, certain red flags warrant prompt ophthalmological referral. These include severe pain, photophobia, decreased visual acuity, or signs of corneal involvement like corneal ulcers or infiltrates. Suspect keratitis in patients presenting with these symptoms and refer immediately to prevent permanent vision impairment. Furthermore, atypical presentations, such as membranous or pseudomembranous conjunctivitis, recurrent or persistent conjunctivitis unresponsive to standard treatment, or suspected gonococcal or chlamydial conjunctivitis also require specialist evaluation. Explore how to implement a standardized referral pathway for acute conjunctivitis to ensure timely and appropriate specialist care when needed. Consider implementing a follow-up protocol to monitor patient response to treatment and identify any potential complications early.
