ICD-10: H44.23

Degenerative myopia, classified under the ICD-10 code H44.23, is a condition characterized by progressive changes in the eye that can lead to significant vision impairment. The diagnosis of degenerative myopia involves several criteria, which are essential for accurate coding and treatment planning. Below are the key diagnostic criteria and considerations for H44.23:

Clinical Criteria for Diagnosis

1. Visual Acuity Assessment

• Patients typically present with reduced visual acuity that cannot be fully corrected with standard refractive lenses. This is often assessed using a Snellen chart or similar visual acuity tests.

2. Ophthalmic Examination

• A comprehensive eye examination is crucial. This includes:
  • Fundoscopy: To evaluate the retina and optic nerve head for signs of degeneration, such as:
  • Posterior staphyloma (a localized outpouching of the sclera)
  • Retinal thinning or atrophy
  • Chorioretinal degeneration
  • Optical Coherence Tomography (OCT): This imaging technique helps visualize the layers of the retina and can reveal structural changes associated with degenerative myopia.

3. Refractive Error Measurement

• The presence of high myopia (typically defined as a refractive error greater than -6.00 diopters) is a significant indicator. The degree of myopia is measured using a phoropter or autorefractor.

4. Family History

• A family history of myopia may be considered, as degenerative myopia can have a genetic component. This information can help in understanding the patient's risk factors.

5. Age of Onset

• Degenerative myopia often begins in childhood or early adulthood. The age of onset can provide context for the diagnosis, as early onset is more indicative of degenerative changes.

6. Exclusion of Other Conditions

• It is essential to rule out other causes of vision loss, such as diabetic retinopathy, retinal detachment, or other retinal diseases. This is typically done through differential diagnosis during the examination.

Additional Considerations

1. Documentation

• Accurate documentation of findings from the eye examination, visual acuity tests, and any imaging studies is critical for coding purposes. This documentation supports the diagnosis of H44.23 and is necessary for insurance reimbursement.

2. Follow-Up

• Regular follow-up examinations are often required to monitor the progression of the condition and adjust treatment plans accordingly. This may include monitoring for complications such as macular degeneration or retinal detachment.

3. Patient Symptoms

• Patients may report symptoms such as blurred vision, difficulty seeing at night, or visual distortions, which can aid in the diagnosis.

In summary, the diagnosis of degenerative myopia, bilateral (ICD-10 code H44.23), relies on a combination of clinical assessments, imaging studies, and thorough patient history. Proper identification of this condition is crucial for effective management and treatment planning, ensuring that patients receive the appropriate care for their visual needs.

Degenerative myopia, bilateral, is classified under the ICD-10-CM code H44.23. This condition is characterized by a progressive elongation of the eyeball, leading to significant refractive errors and potential complications affecting the posterior segment of the eye. Below is a detailed clinical description and relevant information regarding this diagnosis.

Clinical Description

Definition

Degenerative myopia, also known as pathological myopia, is a severe form of myopia (nearsightedness) that typically develops in childhood or early adulthood. It is distinguished from simple myopia by its associated ocular complications and the degree of refractive error, which often exceeds -6.00 diopters. In bilateral cases, both eyes are affected, leading to a range of visual impairments.

Pathophysiology

The primary mechanism behind degenerative myopia involves the abnormal elongation of the eyeball, which can lead to structural changes in the retina and other ocular tissues. This elongation can result in thinning of the retina, the development of lattice degeneration, and an increased risk of retinal detachment. Other complications may include chorioretinal atrophy and macular degeneration, which can severely impact vision.

Symptoms

Patients with bilateral degenerative myopia may experience:
- Blurred vision, particularly for distant objects
- Distorted vision due to retinal changes
- Increased sensitivity to glare
- Difficulty with night vision
- Visual field defects in advanced cases

Diagnosis

Diagnosis of degenerative myopia typically involves a comprehensive eye examination, including:
- Refraction tests to determine the degree of myopia
- Fundoscopy to assess the retina and optic nerve for signs of degeneration
- Optical coherence tomography (OCT) to visualize retinal layers and detect any abnormalities

Degenerative myopia, classified under ICD-10 code H44.23, is a progressive eye condition characterized by excessive elongation of the eyeball, leading to significant vision impairment. This condition often results in various complications, including retinal detachment, choroidal neovascularization, and other retinal pathologies. Understanding the standard treatment approaches for this condition is crucial for managing its symptoms and preventing further vision loss.

Standard Treatment Approaches

1. Regular Monitoring and Eye Examinations

Patients diagnosed with degenerative myopia should undergo regular eye examinations to monitor the progression of the disease. This includes comprehensive dilated eye exams to assess the retina and detect any early signs of complications such as retinal tears or detachments. Early detection is vital for timely intervention, which can significantly impact visual outcomes[1].

2. Corrective Lenses

For many patients, corrective lenses (glasses or contact lenses) are the first line of treatment. These lenses help to improve visual acuity by compensating for the refractive errors associated with myopia. However, they do not halt the progression of the disease but can enhance the quality of life by improving vision[1].

3. Pharmacological Treatments

In cases where complications arise, such as choroidal neovascularization, pharmacological treatments may be necessary. Vascular endothelial growth factor (VEGF) inhibitors are commonly used to manage this condition. These medications can help reduce the growth of abnormal blood vessels in the retina, thereby preserving vision[2][3].

4. Photodynamic Therapy (PDT)

Photodynamic therapy is another treatment option for managing complications associated with degenerative myopia, particularly choroidal neovascularization. This procedure involves the administration of a photosensitizing agent followed by laser treatment, which targets and destroys abnormal blood vessels while sparing surrounding healthy tissue[3][4].

5. Surgical Interventions

In more severe cases, surgical options may be considered. Procedures such as vitrectomy can be performed to address retinal detachments or to remove vitreous hemorrhage. Additionally, scleral buckling may be indicated for retinal detachment associated with degenerative myopia. These surgical interventions aim to repair the retina and restore as much vision as possible[1][2].

6. Lifestyle Modifications

Patients are often advised to adopt lifestyle changes that may help manage their condition. This includes reducing eye strain by taking regular breaks during prolonged near work, ensuring adequate lighting, and maintaining a healthy diet rich in antioxidants, which may support overall eye health[1].

Conclusion

Managing degenerative myopia, particularly bilateral cases as indicated by ICD-10 code H44.23, requires a multifaceted approach that includes regular monitoring, corrective lenses, pharmacological treatments, and possibly surgical interventions. Early detection and intervention are key to preserving vision and preventing complications. Patients should work closely with their eye care professionals to develop a personalized treatment plan that addresses their specific needs and circumstances. Regular follow-ups and adherence to treatment recommendations can significantly improve outcomes for individuals affected by this condition.
