Conjunctivitis due to adenovirus

BILLABLE STATUSYes
IMPLEMENTATION DATEOctober 1, 2015

Code Description

ICD-10 B30.0 is a billable code used to indicate a diagnosis of conjunctivitis due to adenovirus.

Key Diagnostic Point:

Conjunctivitis due to adenovirus is a viral infection of the conjunctiva, the membrane that covers the white part of the eye and the inner eyelids. This condition is characterized by redness, swelling, and discharge from the eye, often accompanied by symptoms such as tearing, itching, and a gritty sensation. Adenoviral conjunctivitis is highly contagious and can spread through direct contact with infected secretions or contaminated surfaces. The incubation period typically ranges from 5 to 12 days, and the condition can last from a few days to several weeks. Diagnosis is primarily clinical, based on the characteristic symptoms and patient history, although laboratory tests such as conjunctival swabs may be performed to confirm the presence of adenovirus. Treatment is generally supportive, focusing on symptom relief, as there are no specific antiviral medications for adenoviral conjunctivitis. Patients are advised to maintain good hygiene practices to prevent the spread of the virus.

Complexity Factors

  • Differentiating between viral and bacterial conjunctivitis
  • Understanding the contagious nature of adenoviral infections
  • Recognizing the need for laboratory confirmation in atypical cases
  • Documenting symptom severity and duration accurately

Audit Risk Factors

  • Inadequate documentation of symptoms and duration
  • Failure to specify the viral etiology
  • Misclassification as bacterial conjunctivitis
  • Lack of supporting lab results in complex cases

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of conjunctivitis, improving the ability to track and manage viral infections like adenoviral conjunctivitis. This specificity aids in better understanding epidemiological trends and resource allocation.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of conjunctivitis, improving the ability to track and manage viral infections like adenoviral conjunctivitis. This specificity aids in better understanding epidemiological trends and resource allocation.
