ICD-10-CM Code H47.22
Hereditary optic atrophy
Billable CodeBillable codes are sufficient justification for admission to an acute care hospital when used a principal diagnosis.
H47.22 is a billable ICD code used to specify a diagnosis of hereditary optic atrophy. A 'billable code' is detailed enough to be used to specify a medical diagnosis.
The ICD code H472 is used to code Leber's hereditary optic neuropathy
Leber’s hereditary optic neuropathy (LHON) or Leber optic atrophy is a mitochondrially inherited (transmitted from mother to offspring) degeneration of retinal ganglion cells (RGCs) and their axons that leads to an acute or subacute loss of central vision; this affects predominantly young adult males. However, LHON is only transmitted through the mother as it is primarily due to mutations in the mitochondrial (not nuclear) genome and only the egg contributes mitochondria to the embryo. LHON is usually due to one of three pathogenic mitochondrial DNA (mtDNA) point mutations. These mutations are at nucleotide positions 11778 G to A, 3460 G to A and 14484 T to C, respectively in the ND4, ND1 and ND6 subunit genes of complex I of the oxidative phosphorylation chain in mitochondria. Men cannot pass on the disease to their offspring.

Equivalent ICD-9 Code GENERAL EQUIVALENCE MAPPINGS (GEM)
This is the official exact match mapping between ICD9 and ICD10, as provided by the General Equivalency mapping crosswalk. This means that in all cases where the ICD9 code 377.16 was previously used, H47.22 is the appropriate modern ICD10 code.
