What information is required to accurately code hypertension retinopathy in ICD-10-CM?

To accurately code hypertension retinopathy in ICD-10-CM, knowing which eye(s) is/are affected is essential. This detail helps to clarify the diagnosis and allows coders to select the appropriate code that specifies whether the condition involves one eye (unilateral) or both eyes (bilateral). Codes within ICD-10-CM for hypertension retinopathy are often differentiated based on this bilateral or unilateral distinction, which directly impacts both clinical documentation and billing processes.

While other factors like the duration of hypertension or the presence of symptoms may be relevant in a clinical context, they do not directly influence the coding of the retinopathy. Certainly, the age of the patient can have implications in certain cases, but it does not play a critical role in the initial coding of hypertension retinopathy. Therefore, the specificity required for coding is primarily focused on the anatomical details regarding which eye(s) is/are impacted.
