Valid for Submission
H52.229 is a billable diagnosis code used to specify a medical diagnosis of regular astigmatism, unspecified eye. The code H52.229 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 H52.229 might also be used to specify conditions or terms like against-the-rule astigmatism, oblique astigmatism, regular astigmatism, regular astigmatism - corneal, regular astigmatism - lenticular , with-the-rule astigmatism, etc.
Unspecified diagnosis codes like H52.229 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:
- Against-the-rule astigmatism
- Oblique astigmatism
- Regular astigmatism
- Regular astigmatism - corneal
- Regular astigmatism - lenticular
- With-the-rule astigmatism

Convert H52.229 to ICD-9 Code
The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code H52.229 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
Also called: Farsightedness, Hyperopia, Myopia, Nearsightedness
The cornea and lens of your eye helps you focus. Refractive errors are vision problems that happen when the shape of the eye keeps you from focusing well. The cause could be the length of the eyeball (longer or shorter), changes in the shape of the cornea, or aging of the lens.
Four common refractive errors are
- Myopia, or nearsightedness - clear vision close up but blurry in the distance
- Hyperopia, or farsightedness - clear vision in the distance but blurry close up
- Presbyopia - inability to focus close up as a result of aging
- Astigmatism - focus problems caused by the cornea
The most common symptom is blurred vision. Other symptoms may include double vision, haziness, glare or halos around bright lights, squinting, headaches, or eye strain.
Glasses or contact lenses can usually correct refractive errors. Laser eye surgery may also be a possibility.
