About H35.41

H35.41 is the ICD-10-CM diagnosis code for Lattice degeneration of retina. It belongs to category H35 (other retinal disorders), block H30-H36 (disorders of choroid and retina) and chapter 7 (diseases of the eye and adnexa). It is a header code, so it can't be reported by itself; one of its 4 subcodes must be used instead.

Related codes cover unspecified peripheral retinal degeneration (H35.40), Microcystoid degeneration of retina (H35.42), Paving stone degeneration of retina (H35.43), age-related reticular degeneration of retina (H35.44), secondary pigmentary degeneration (H35.45) and secondary vitreoretinal degeneration (H35.46).
