H04.302 Unspecified dacryocystitis of left lacrimal passage

ICD10CM code

#### Name of the Condition
- Unspecified Dacryocystitis of Left Lacrimal Passage

#### Summary
Dacryocystitis is an inflammation of the lacrimal sac, often due to the obstruction of the nasolacrimal duct. When it occurs without specific indication, it is classified as unspecified. It primarily manifests in the left passage, causing discomfort and potential infection.

#### Causes
- Typically caused by a blockage in the nasolacrimal duct.
- Bacterial infections are the most common direct cause.
- May also occur due to mucous membrane swelling from allergies.

#### Risk Factors
- Age: Common in infants and older adults.
- Chronic sinusitis or rhinitis.
- Facial trauma or abnormal nasolacrimal duct anatomy.

#### Symptoms
- Pain, swelling, and redness in the inner corner of the eye.
- Tearing and discharge from the affected eye.
- Fever may occur in cases of infection.

#### Diagnosis
- Physical examination of the eye and surrounding areas.
- Imaging tests like CT or MRI if structural issues are suspected.
- Culture of the discharge to identify bacterial infection.

#### Treatment Options
- Antibiotic therapy for bacterial infections.
- Warm compresses to reduce swelling.
- Surgical procedures if caused by duct obstruction.

#### Prognosis and Follow-Up
- Generally, good prognosis with appropriate treatment.
- Regular follow-ups to manage and prevent recurring infections.
- Sometimes surgery may be required for persistent cases.

#### Complications
- Chronic infection can lead to abscess formation.
- Can contribute to more severe eye infections if untreated.

#### Lifestyle & Prevention
- Good eye hygiene; avoid rubbing the eyes.
- Addressing allergies promptly to reduce nasal congestion.
- Minimize exposure to known irritants.

#### When to Seek Professional Help
- Persistent pain, swelling, and redness around the eye.
- Development of fever or worsening symptoms.
- Symptoms not improving with initial home care treatments.

#### Tips for Medical Coders
- Verify laterality to ensure coding pertains to the left lacrimal passage.
- Ensure no other specified forms of dacryocystitis are documented to validate use of unspecified code.
