Unspecified acute conjunctivitis, right eye

This code indicates an acute inflammation of the conjunctiva in the right eye, where the specific causative agent or type of conjunctivitis has not been identified by the provider. It represents a sudden onset of conjunctival redness, discharge, and irritation without further diagnostic specificity.

Apply this code when documentation clearly states "acute conjunctivitis, right eye" but lacks details regarding its etiology (e.g., bacterial, viral, allergic). This is appropriate when the physician has not yet determined the specific type of conjunctivitis or when the documentation does not provide enough information for a more specific code.

• Do not use if the documentation specifies the type of acute conjunctivitis (e.g., viral, bacterial, allergic); instead, select a more specific code.
• Ensure laterality is clearly documented for the right eye; if both eyes are affected, use the bilateral code or separate codes for each eye if specified.
• Avoid using this code if the conjunctivitis is documented as chronic; refer to the H10.4- series for chronic forms.
