Unspecified peripheral retinal degeneration

This code represents a general diagnosis of deterioration of the outer edges of the retina, the light-sensitive tissue at the back of the eye. This degeneration is not specified as cystic, lattice, or other named types, and the specific cause or pattern of the degeneration is unknown or not documented. It indicates a non-specific form of retinal thinning or changes in the peripheral retina.

Use this code when the physician documents "peripheral retinal degeneration" without further specifying the type (e.g., lattice, snail-track, paving-stone). This code is appropriate when the documentation indicates a non-specific or unspecified form of peripheral retinal degeneration. Supporting documentation would include ophthalmic exam findings noting peripheral retinal changes without a definitive classification.

• Avoid using this code if a more specific type of peripheral retinal degeneration (e.g., lattice, cystic) is documented; instead, use the appropriate specific code from the H35.4 subcategory.
• Ensure the documentation clearly states "unspecified" or lacks further detail regarding the type of degeneration to justify using this code.
• Consider laterality if specified in the documentation, though this code is for unspecified laterality. If right or left eye is documented, a more specific laterality code (H35.41x or H35.42x) should be used.
