ICD-10 Code H05.813 – Cyst of bilateral orbits (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H05.813 – Cyst of bilateral orbits
What it is
H05.813 identifies a cyst affecting both orbits, the bony eye sockets that contain the eyes and supporting structures. Use it when documentation clearly states bilateral orbital cysts.
Clinical signs
Clinical features vary; refer to documentation. Orbital cysts may be found on imaging or exam and can be associated with swelling, fullness, or eye displacement depending on size and location.
When to use this code
Use this code when the provider documents a cyst in both orbits, or when bilateral orbital cysts are confirmed in the assessment. It may also fit imaging reports that specifically identify bilateral orbital cysts and are accepted in the record.
If the note only mentions an orbital mass, lesion, or cyst without laterality, check documentation before assigning H05.813. Coding should match the exact anatomic site and bilateral designation.
Do not use for
Do not use this code for a cyst in one orbit, an eyelid cyst, or a nonspecific eye lesion. Check documentation if the record does not clearly state bilateral orbital involvement.
Coding tip
Confirm both laterality and orbital location in the provider’s note or imaging report before coding H05.813.
