Understanding Dry Macular Degeneration (Nonexudative AMD or Atrophic AMD) is crucial for accurate clinical documentation and medical coding. This resource provides information on diagnosing, staging, and managing Dry AMD, including relevant ICD-10 codes and clinical findings. Learn about the symptoms, risk factors, and treatment options for Nonexudative AMD to improve patient care and ensure proper healthcare reimbursement. Explore the latest research and best practices for Atrophic AMD diagnosis and management.
Also known as
Dry age-related macular degeneration

Follow this step-by-step guide to choose the correct ICD-10 code.
Is the macular degeneration dry (nonexudative/atrophic)?
Yes
Is there geographic atrophy?
No
Do NOT code for dry macular degeneration. See exudative AMD guidelines.
When to use each related code
| Description |
|---|
| Gradual central vision loss, dry macular changes. |
| Rapid central vision loss, wet macular changes. |
| Early or intermediate AMD, drusen, pigmentary changes. |
Missing or incorrect laterality (right, left, bilateral) for dry macular degeneration impacts reimbursement and data accuracy.
Unspecified or inaccurate staging (early, intermediate, advanced) of dry AMD can lead to coding errors and claims denials.
Misdiagnosis or miscoding of wet AMD (neovascular) as dry AMD can significantly impact treatment and reimbursement.
Q: How can I differentiate between dry macular degeneration stages using multimodal imaging techniques in clinical practice?
A: Differentiating dry macular degeneration stages, specifically geographic atrophy (GA) and early/intermediate dry AMD, relies heavily on multimodal imaging. Fundus autofluorescence (FAF) reveals areas of hypo-autofluorescence corresponding to retinal pigment epithelium (RPE) atrophy in GA, while spectral-domain optical coherence tomography (SD-OCT) can identify drusen size and pigmentary changes beneath the RPE in earlier stages. Near-infrared reflectance (NIR) imaging helps visualize areas of RPE loss more clearly. In intermediate dry AMD, SD-OCT can also detect reticular pseudodrusen. Combining these techniques allows for comprehensive assessment of lesion characteristics and accurate staging. For advanced GA, OCT angiography can be used to evaluate choriocapillaris flow deficits. Explore how multimodal imaging integration enhances diagnostic accuracy in your practice and consider implementing standardized imaging protocols for improved disease management. Learn more about the specific benefits and limitations of each imaging modality in dry AMD staging.
Q: What are the best evidence-based management strategies for patients with intermediate dry age-related macular degeneration progressing towards geographic atrophy?
A: Managing intermediate dry age-related macular degeneration (AMD) with a high risk of progression to geographic atrophy (GA) involves a multifaceted approach. While there is currently no approved treatment to prevent or reverse dry AMD, certain interventions can help slow progression and preserve vision. The Age-Related Eye Disease Study 2 (AREDS2) demonstrated the benefit of specific antioxidant vitamin and mineral supplementation (vitamin C, vitamin E, lutein, zeaxanthin, zinc, copper) in reducing the risk of progression to advanced AMD. Regular monitoring with fundus photography, autofluorescence, and optical coherence tomography (OCT) is essential to detect early signs of GA. Patient education regarding lifestyle modifications, such as smoking cessation, maintaining a healthy diet, and controlling blood pressure, are crucial. Emerging therapies targeting complement activation and visual cycle modulation are under investigation for GA and should be discussed with patients when appropriate. Consider implementing a proactive approach to patient management that includes regular follow-up, comprehensive eye exams, and patient counseling regarding the latest advancements in dry AMD research and treatment options.
Patient presents with complaints consistent with dry macular degeneration (nonexudative AMD, atrophic AMD). Visual acuity decline, particularly central vision loss, was reported. The patient notes increasing difficulty with reading and recognizing faces. Amsler grid testing revealed distorted or missing areas in the central visual field. Funduscopic examination demonstrated the presence of drusen, pigmentary changes, and geographic atrophy in the macula. No signs of choroidal neovascularization or exudation were observed, confirming the diagnosis of non-exudative age-related macular degeneration. Differential diagnoses considered included cataracts and other retinal dystrophies. Patient education was provided regarding the progressive nature of dry AMD, the importance of regular monitoring, and available low vision aids. Management currently focuses on lifestyle modifications including smoking cessation, nutritional guidance with emphasis on AREDS-2 formula vitamins, and strategies for maximizing remaining vision. Follow-up appointment scheduled for reassessment of macular degeneration progression and consideration for future therapeutic options if indicated. ICD-10 code H35.32 (geographic atrophy) is documented for this encounter. CPT code 92004 was billed for the ophthalmological examination.
