2025 ICD-10-CM code H10.509
(Active) Effective Date: N/A Disorders of conjunctiva - Blepharoconjunctivitis 7 (Diseases of the eye and adnexa (H00-H59)) Feed
Unspecified blepharoconjunctivitis affecting an unspecified eye.
Medical necessity for the diagnosis of unspecified blepharoconjunctivitis must be supported by the documentation of the patient's symptoms and clinical findings. The medical record should clearly demonstrate the need for medical intervention.
Diagnosis and treatment of blepharoconjunctivitis. This includes a thorough eye exam, identifying the underlying cause, and prescribing appropriate treatment such as warm compresses, eyelid scrubs, or topical medications.
In simple words: This code refers to a type of pink eye where both the eyelid and the white part of the eye are inflamed, but it doesn't specify which eye is affected.
Unspecified blepharoconjunctivitis, unspecified eye. This code indicates a combined inflammation of the eyelid (blepharitis) and the conjunctiva (conjunctivitis) without specifying which eye is affected.
Example 1: A patient presents with redness, irritation, and swelling in both eyelids and the white part of their eyes. The physician diagnoses blepharoconjunctivitis but does not specify which eye is affected, using H10.509., A patient with a history of blepharitis develops conjunctivitis. The physician diagnoses blepharoconjunctivitis, unspecified eye, using H10.509., A patient reports blurry vision, gritty sensation, and swollen eyelids. The doctor diagnoses unspecified blepharoconjunctivitis affecting an unspecified eye and uses H10.509.
Documentation should include the signs and symptoms of blepharoconjunctivitis, including redness, swelling, discharge, itching, burning, and foreign body sensation. It should also mention any associated conditions such as dry eye or meibomian gland dysfunction. Laterality (which eye is affected) needs clarification; in cases of unspecified laterality,"unspecified eye" should be explicitly documented to justify the use of H10.509. The documentation should also include the clinical findings and treatment plan.
