Valid for Submission
H59.099 is a billable diagnosis code used to specify a medical diagnosis of other disorders of unspecified eye following cataract surgery. The code H59.099 is valid during the fiscal year 2021 from October 01, 2020 through September 30, 2021 for the submission of HIPAA-covered transactions.
The ICD-10-CM code H59.099 might also be used to specify conditions or terms like brown-mclean syndrome, strabismus following cataract surgery, strabismus following ocular surgery, visual loss after cataract extraction or vitreous syndrome following cataract surgery.
Unspecified diagnosis codes like H59.099 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Brown-McLean Syndrome
- Strabismus following cataract surgery
- Strabismus following ocular surgery
- Visual loss after cataract extraction
- Vitreous syndrome following cataract surgery

The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code H59.099 its ICD-9 equivalent. The approximate mapping means there is not an exact match between the ICD-10 code and the ICD-9 code and the mapped code is not a precise representation of the original code.
Information for Patients
A cataract is a clouding of the lens in your eye. It affects your vision. Cataracts are very common in older people. By age 80, more than half of all Americans either have a cataract or have had cataract surgery.
A cataract can occur in either or both eyes. It cannot spread from one eye to the other. Common symptoms are
- Blurry vision
- Colors that seem faded
- Glare - headlights, lamps or sunlight may seem too bright. You may also see a halo around lights.
- Not being able to see well at night
- Double vision
- Frequent prescription changes in your eye wear
Cataracts usually develop slowly. New glasses, brighter lighting, anti-glare sunglasses or magnifying lenses can help at first. Surgery is also an option. It involves removing the cloudy lens and replacing it with an artificial lens. Wearing sunglasses and a hat with a brim to block ultraviolet sunlight may help to delay cataracts.
