Allergic conjunctivitis is a common condition affecting millions worldwide, causing discomfort and impacting daily life. In the medical field, accurate diagnosis and coding are crucial for patient care and insurance purposes. The International Classification of Diseases, 10th Revision, Clinical Modification (ICD-10-CM) provides a standardized system for classifying diagnoses. For cases of other chronic allergic conjunctivitis, the specific code is H10.45.
What is ICD-10-CM Code H10.45?
ICD-10-CM code H10.45 is designated as “Other chronic allergic conjunctivitis.” This code is used to classify cases of persistent allergic conjunctivitis that are not categorized under more specific types, such as vernal conjunctivitis or atopic conjunctivitis. It’s important to note that this is a billable/specific code, meaning it is precise enough to be used for reimbursement claims. The code officially came into effect on October 1, 2015, with the adoption of ICD-10-CM, and the latest 2025 edition remains current as of October 1, 2024. This code is specific to the American ICD-10-CM version, and international versions may have variations.

Synonyms and Related Terms for H10.45
To better understand H10.45, it’s helpful to know some of the terms that are considered approximate synonyms:
- Perennial allergic conjunctivitis
- Bilateral perennial allergic conjunctivitis
- Perennial allergic conjunctivitis of bilateral eyes
- Perrenial allergic conjunctivitis (likely a misspelling, but still listed)
- Seasonal allergic conjunctivitis (While seemingly contradictory to “chronic,” in some contexts, persistent seasonal allergies might be classified under chronic if they occur over extended periods each year).
These synonyms highlight that H10.45 often refers to ongoing, year-round allergic conjunctivitis, rather than acute or seasonal forms.
Importance of Accurate Diagnosis Coding
Using the correct ICD-10-CM code like H10.45 is vital for several reasons:
- Reimbursement: Accurate coding ensures that healthcare providers receive appropriate reimbursement for their services. Using a billable and specific code like H10.45 is necessary for claims processing.
- Data Collection and Statistics: Standardized coding allows for the collection of consistent data on disease prevalence and trends. This information is crucial for public health research and resource allocation.
- Effective Communication: ICD-10-CM codes provide a common language for healthcare professionals to communicate about diagnoses, regardless of location or specialty.
In summary, ICD-10-CM code H10.45 is a key tool for classifying and documenting cases of other chronic allergic conjunctivitis. Understanding its definition, synonyms, and importance contributes to accurate medical coding and effective healthcare management.
