Other corneal degeneration
Billable CodeBillable codes are sufficient justification for admission to an acute care hospital when used a principal diagnosis.
H18.49 is a billable ICD code used to specify a diagnosis of other corneal degeneration. A 'billable code' is detailed enough to be used to specify a medical diagnosis.
The ICD code H184 is used to code Arcus senilis
Arcus senilis (or arcus senilis corneae) is a white, grey, or blue opaque ring in the corneal margin (peripheral corneal opacity), or white ring in front of the periphery of the iris. It is present at birth, but then fades; however, it is quite commonly present in the elderly. It can also appear earlier in life as a result of hypercholesterolemia. Arcus senilis can be confused with the limbus sign, which reflects calcium rather than lipid deposits.
|ICD 9 Code:||371.41|
Four representative slides of corneal arcus - arcus deposits tend to start at 6 and 12 o'clock and fill in until becoming completely circumferential. There is a thin, clear section separating the arcus from the limbus, known as the lucid interval of Vogt. Image from Zech and Hoeg, 2008.
