2025 ICD-10-CM code H31.29
(Active) Effective Date: N/A Diseases of the eye and adnexa - Hereditary choroidal dystrophy 7 Feed
This code signifies other hereditary choroidal dystrophy, distinct from specified types like choroideremia or central areolar choroidal dystrophy.
Laterality modifiers can be applied to specify which eye is affected (right, left, or bilateral).
The medical necessity for using H31.29 arises when a patient presents with signs and symptoms consistent with choroidal dystrophy, and other, more specific, hereditary forms have been ruled out through diagnostic testing and clinical evaluation. This code specifies the underlying cause of the visual impairment, which guides treatment strategies and facilitates appropriate patient management and genetic counseling.
Diagnosis and management of this condition falls under ophthalmologists, eye specialists who can perform a comprehensive eye examination to assess the extent of the choroidal dystrophy and provide appropriate management and follow-up care.
In simple words: This code represents an inherited eye condition affecting the back part of the eye, leading to gradual vision impairment. It's different from other, more specific inherited eye problems.
This code encompasses various inherited disorders affecting the choroid, excluding specific conditions like choroideremia, central areolar choroidal dystrophy, and gyrate atrophy of the choroid. These conditions primarily impact the choroid, a vascular layer of the eye supplying blood to the retina.Hereditary choroidal dystrophies are genetically transmitted and lead to progressive vision loss.
Example 1: A 35-year-old patient presents with progressive night blindness and difficulty reading. Upon examination, the ophthalmologist notes pigmentary changes and atrophy in the choroid, and genetic testing confirms a diagnosis of a rare, unspecified hereditary choroidal dystrophy, hence H31.29 is used., A 50-year-old individual with a family history of vision loss reports blurred central vision. The ophthalmologist identifies areas of choroidal thinning and degeneration not consistent with other specific dystrophies, and after excluding other causes, assigns H31.29 to denote other hereditary choroidal dystrophy., A young patient exhibits unusual retinal changes. After extensive testing to rule out other conditions, including specific hereditary choroidal dystrophies, the diagnosis is an unclassified form of inherited choroidal dystrophy, necessitating the use of code H31.29.
Detailed clinical examination findings, including visual acuity assessment, fundus photography, and visual field tests. Genetic testing results confirming the diagnosis. Family history of similar eye conditions. Differential diagnosis ruling out other causes of choroidal changes.
