Follow this step-by-step guide to choose the correct ICD-10 code.
Is the choroidal nevus malignant?
When to use each related code
| Description |

| Benign pigmented spot on the choroid. |
| Malignant tumor of the choroid. |
| Flat, well-defined pigmented spot on the retina, often with surrounding halo. Usually benign. Fundus examination is key. CHRPE. |
Missing or incorrect laterality (right, left, bilateral) for Choroidal Nevus impacts reimbursement and data accuracy. Important for medical coding audits.
Accurate differentiation between benign nevus (D31.1) and malignant melanoma (C69.3) of choroid is crucial for correct diagnosis coding and treatment.
Insufficient documentation detailing size, location, and other characteristics of the nevus can lead to coding errors and CDI queries for medical record review.
Q: How can I differentiate a small choroidal nevus from a small choroidal melanoma using multimodal imaging techniques?
A: Differentiating a small choroidal nevus from a small choroidal melanoma is crucial for appropriate management and can be challenging clinically. Multimodal imaging plays a vital role in this process. Ultrasound, especially enhanced depth imaging optical coherence tomography (EDI-OCT), can assess internal reflectivity, tumor thickness, and the presence of subretinal fluid, features helpful in distinguishing the two. Fundus autofluorescence (FAF) can reveal lipofuscin accumulation, often less pronounced in melanoma. Optical coherence tomography angiography (OCT-A) helps evaluate vascular patterns, with melanoma demonstrating more irregular vasculature. While each modality provides valuable information, using them in combination improves diagnostic accuracy. Consider implementing a standardized multimodal imaging protocol for all suspicious choroidal lesions to improve early detection and risk stratification. Explore how combining these techniques can enhance your diagnostic confidence in challenging cases.
Q: What are the most reliable risk factors for malignant transformation of a choroidal nevus, and how should I monitor these patients based on risk stratification?
A: Several risk factors increase the likelihood of a choroidal nevus transforming into melanoma. Thickness greater than 2mm, presence of subretinal fluid, orange pigment overlying the lesion, proximity to the optic disc, and documented growth are among the most significant. To manage patients effectively, risk stratification based on these factors is essential. Low-risk nevi typically require less frequent monitoring, such as annual fundus photography. Patients with moderate-risk features may necessitate more frequent imaging, including OCT and autofluorescence every 6-12 months. High-risk nevi warrant close observation with multimodal imaging, including ultrasound and OCT-A, every 3-6 months and referral to an ocular oncologist should be considered. Learn more about developing a comprehensive risk assessment and monitoring protocol for choroidal nevi to ensure timely intervention and optimal patient outcomes.
Patient presents for ophthalmologic evaluation of a choroidal nevus, also known as a benign neoplasm of the choroid or ocular nevus. History includes [mention specific symptoms or lack thereof e.g., blurry vision, visual field defects, floaters, flashes, or asymptomatic]. Review of systems is otherwise unremarkable. Ocular examination reveals a pigmented lesion consistent with a choroidal nevus located in the [specify location, e.g., superior temporal quadrant of the right eye]. The lesion measures [specify dimensions, e.g., 3mm x 2mm] with [describe characteristics, e.g., well-defined margins and homogenous pigmentation]. Fundus photography and optical coherence tomography (OCT) were performed for baseline documentation and to assess for features suggestive of malignant transformation, such as subretinal fluid, orange pigment, or overlying drusen. Differential diagnosis includes choroidal melanoma, congenital hypertrophy of the retinal pigment epithelium (CHRPE), and melanocytoma. Given the clinical presentation and imaging characteristics, the diagnosis of choroidal nevus is favored. The patient was educated on the benign nature of the lesion, the importance of regular monitoring for any changes, and signs and symptoms to watch for. A follow-up appointment in [specify timeframe, e.g., 6 months] is scheduled for repeat fundus photography and OCT to monitor for growth or other changes concerning for malignant transformation. ICD-10 code D31.1 (Benign neoplasm of choroid) is appropriate for this encounter.
