ICD10 code of Leber Hereditary Optic Neuropathy and ICD9 code

Leber Hereditary Optic Neuropathy (LHON) is a rare genetic disorder that primarily affects the optic nerves, leading to vision loss. The International Classification of Diseases, Tenth Revision (ICD-10) provides a specific code for LHON, which is H47.23. This code falls under the broader category of "Other optic neuropathies," denoting conditions that involve damage or dysfunction of the optic nerves.

In the previous revision, ICD-9, the code for LHON was 377.14. This code was titled "Optic atrophy, hereditary" and was part of the "Other disorders of optic nerve" category. However, it's important to note that ICD-9 codes are no longer in use, as they have been replaced by the updated ICD-10 system.

LHON is a mitochondrial disorder caused by mutations in the mitochondrial DNA. It primarily affects young adults, particularly males, and typically leads to bilateral central vision loss. The condition may progress rapidly, with symptoms such as blurred or clouded vision, color vision impairment, and eventual blindness. While LHON primarily affects the optic nerves, it can also lead to other neurological symptoms, such as movement disorders or cardiac conduction defects in rare cases.

Early diagnosis of LHON is crucial for genetic counseling and potential treatment options. Genetic testing plays a significant role in confirming the presence of LHON-related mutations. Although there is currently no cure for LHON, certain therapeutic approaches, such as idebenone, have shown some promise in potentially slowing down disease progression.

In conclusion, Leber Hereditary Optic Neuropathy is assigned the ICD-10 code H47.23, while in the previous ICD-9 system, it was coded as 377.14. It is a rare genetic disorder characterized by optic nerve damage and vision loss, primarily affecting young adults.
