H50: Other strabismus

H50 refers to Other strabismus, a set of eye movement and focusing disorders affecting alignment and visual clarity. These conditions can be congenital or acquired, and range from minor visual disturbances to significant functional impairments in eye coordination or focus.

Symptoms

• Double vision (diplopia) – Especially in paralytic strabismus (H49)
• Eye misalignment – Characteristic of strabismus (H49, H50)
• Crossed eyes or outward deviation – Found in esotropia or exotropia (H50)
• Difficulty with depth perception – Seen in binocular vision disorders (H51)
• Eye strain or fatigue – Common in uncorrected refractive errors (H52)
• Blurry near or far vision – Typical of hyperopia, myopia, or astigmatism (H52)
• Squinting or frequent blinking – May indicate accommodation problems

Diagnosis

Diagnosis of Other strabismus includes visual acuity testing, cover/uncover and Hirschberg tests, prism testing, refraction testing, and assessments of binocular coordination. Neurological exams and imaging may be needed for paralytic or acquired forms of strabismus.

ICD10 Code Usage

ICD10 code H50 is used in optometry, ophthalmology, pediatric eye care, and neurology. It assists with clinical documentation, corrective lens prescriptions, orthoptic therapy planning, vision therapy, and strabismus surgery approvals.

Related Codes

• H49 – Paralytic strabismus
• H51 – Other disorders of binocular movement
• H52 – Disorders of refraction and accommodation

FAQs

Q1: What is ICD10 code H50?
A: It represents Other strabismus, covering alignment and focusing issues of the eyes like strabismus, binocular movement disorders, and refractive errors.

Q2: Are these conditions treatable?
A: Yes—treatments include eyeglasses, prism lenses, patching therapy, vision therapy, or strabismus surgery depending on severity and cause.

Q3: Is strabismus always present from birth?
A: Not always—some cases are acquired due to trauma, neurological issues, or decompensation of a previously latent misalignment.

Q4: What is the difference between H49 and H50?
A: H49 refers to paralytic causes (nerve palsy), while H50 includes non-paralytic types such as esotropia or exotropia.

Q5: Who manages these conditions?
A: Optometrists, ophthalmologists, pediatric specialists, and vision therapists.

Conclusion

ICD10 code H50 ensures precise classification of Other strabismus, guiding timely intervention and helping restore optimal vision, alignment, and eye function through clinical care and corrective therapies.
