2025 ICD-10-CM code A21.1

Oculoglandular tularemia is a rare bacterial infection of the eye caused by Francisella tularensis.

Use additional code to identify resistance to antimicrobial drugs (Z16.-).Certain localized infections are excluded and can be found in other chapters. Carrier or suspected carrier of infectious disease (Z22.-), infectious and parasitic diseases complicating pregnancy, childbirth and the puerperium (O98.-), infectious and parasitic diseases specific to the perinatal period (P35-P39) and influenza and other acute respiratory infections (J00-J22) are excluded.

Medical necessity for treatment of oculoglandular tularemia is established by the confirmed diagnosis, as it can lead to serious complications if left untreated.

Clinicians diagnose oculoglandular tularemia based on patient history, symptoms, physical examination, and laboratory tests like blood cultures, serologic tests, PCR, and microscopic analysis of specimens from lymph nodes or lesions. Treatment involves antibiotics such as doxycycline, ciprofloxacin, streptomycin, and tetracycline. Patient education on prevention includes handwashing, consuming safe food and water, and wearing gloves when handling dead animals.

In simple words: Oculoglandular tularemia is a rare eye infection you can get from touching your eye after handling infected meat or from contaminated water or fluids getting in your eye. It makes your eye red, swollen, and painful, and sometimes pus comes out. The lymph nodes near your ear might also swell up.

Oculoglandular tularemia is a rare form of tularemia, a zoonotic bacterial disease caused by Francisella tularensis. This form is characterized by infection of the eye, resulting in symptoms such as pain, redness, swelling, and discharge, often accompanied by swollen lymph nodes around the ear.

Example 1: A hunter develops eye pain, redness, and discharge after handling a rabbit carcass. Swollen preauricular lymph nodes are also noted. Diagnostic tests confirm oculoglandular tularemia., A laboratory worker accidentally splashes contaminated fluid into their eye, leading to oculoglandular tularemia. , A child develops oculoglandular tularemia after swimming in a contaminated pond.

Documentation should include patient history (e.g., exposure to infected animals, tick bites, contaminated water), presenting symptoms (e.g., eye pain, redness, swelling, discharge, swollen lymph nodes), physical exam findings, and laboratory results confirming the diagnosis of oculoglandular tularemia.
