Laterality matters! 🔹 Right eye (1) 🔹 Left eye (2) 🔹 Bilateral (3) 🔹 Unspecified (9) Example: H25.11 – Age-related nuclear cataract, right eye 2. Always note the stage and type of disease, especially for 🔹 Glaucoma: Requires stage (mild, moderate, severe) 🔹 Diabetic retinopathy: Needs type, severity, and presence of macular edema 3. If the condition is linked to diabetes, use both the diabetes code (E11.3x) and the eye disorder code (H36.x) 4. Use additional codes for: 🔹 Postoperative status (Z98.89) 🔹 Eye prosthesis or implants (Z96.1x) 04:45 Section 4: Real-Life Case Examples 🔸 Example 1: A patient with bilateral age-related cataracts. ✅ Code: H25.13 🔸 Example 2: Type 2 diabetic with moderate nonproliferative diabetic retinopathy, right eye, without macular edema. ✅ Codes: E11.329, H36.811 🔸 Example 3: Acute viral conjunctivitis, left eye. ✅ Code: H10.212 🔸 Example 4: Primary open-angle glaucoma, left eye, severe stage. ✅ Code: H40.11X3 05:36 Section 5: Common Diagnoses from Chapter 🔹 H10.9 – Conjunctivitis, unspecified 🔹 H25.13 – Age-related cataract, bilateral 🔹 H40.11X2 – Primary open-angle glaucoma, left eye, moderate stage 🔹 H52.13 – Myopia, bilateral 🔹 H54.0 – Blindness, both eyes 🔹 H36.0 – Diabetic retinopathy #ICD10CM #ICD10Chapter7 #EyeCoding #OphthalmologyCoding #CataractCoding #DiabeticRetinopathy #MedicalCodingTutorial #RHITPrep #ICD10CM2025 #GlaucomaCoding medical coding medical coding classes online medical coding and billing medical coding for beginners medical coding course medical coding interview questions for freshers medical coding course details medical coding in tamil medical coding jobs for freshers medical coding jobs medical coding malayalam medical coding in telugu medical coding work demo medical coding interview
