Retinal hemorrhage, left eye

This code signifies bleeding within the retina of the left eye. This can manifest as various types of hemorrhages, such as dot-and-blot, flame-shaped, or preretinal, indicating damage to the retinal blood vessels.

Apply this code when documentation explicitly states a retinal hemorrhage is present in the left eye. This diagnosis is often associated with conditions like diabetic retinopathy, retinal vein occlusion, or trauma. Look for ophthalmologist notes detailing the location and laterality of the hemorrhage.

• Ensure the documentation specifies "left eye" for accurate laterality. If unspecified, query the provider.
• Distinguish from subconjunctival hemorrhage (H11.3-) or vitreous hemorrhage (H43.1-), which are distinct conditions.
• Always code the underlying cause of the retinal hemorrhage, if known and documented, as a primary diagnosis when applicable.
