icd 10 dx code for pellucid marginal degeneration

Full Answer

What is pellucid marginal degeneration?

Pellucid marginal degeneration is a condition characterized by peripheral corneal thinning and corneal ectasia. Pellucid marginal degeneration (PMD) is a non-inflamatory thinning of the peripheral cornea.

What is the ICD 10 code for bilateral peripheral corneal degeneration?

Peripheral corneal degeneration, bilateral. H18.463 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2020 edition of ICD-10-CM H18.463 became effective on October 1, 2019. This is the American ICD-10-CM version of H18.463 - other international versions of ICD-10 H18.463 may differ.

What is the ICD 10 code for chondromalacia?

H18.469 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2022 edition of ICD-10-CM H18.469 became effective on October 1, 2021. This is the American ICD-10-CM version of H18.469 - other international versions of ICD-10 H18.469 may differ.

What is pellucid marginal corneal degeneration?

Pellucid marginal corneal degeneration (PMD) is a rare ectatic disorder which typically affects the inferior peripheral cornea in a crescentic fashion. The condition is most commonly found in males and usually appears between the 2nd and 5th decades of life affecting all ethnicities.

Is pellucid marginal degeneration progressive?

Pellucid marginal corneal degeneration is a progressive peripheral corneal thinning disorder with an adjoining area of ectasia above it. It is a relatively rare ocular condition and usually occurs in males in the 2nd to 5th decades.

How is pellucid marginal degeneration diagnosed?

Pellucid marginal degeneration is diagnosed by corneal topography. Corneal pachymetry may be useful in confirming the diagnosis. Treatment usually consists of vision correction with eyeglasses or contact lenses. Intacs implants, corneal collagen cross-linking, and corneal transplant surgery are additional options.

Is pellucid marginal degeneration keratoconus?

Unlike keratoconus, which usually stops progressing in the third or fourth decade of life, pellucid marginal degeneration is progressive throughout the patients' lifetime and is non-inflammatory. Corneas are usually clear and without lipid deposition.

What is the cause of pellucid marginal degeneration?

The etiology of pellucid marginal degeneration has not been clearly established, but collagen abnormalities, as seen in keratoconus, have been reported. The thinned and presumably weakened cornea may protrude as a result of the positive intraocular pressure.

How is pellucid marginal degeneration treated?

In early-to-moderate cases, contact lenses are beneficial in providing visual rehabilitation. Spectacles and toric hydrophilic contact lenses are useful in mild pellucid marginal degeneration. Spherical hydrophilic contact lenses cannot correct the astigmatism associated with this condition.

Is pellucid marginal degeneration bilateral?

Pellucid Marginal Degeneration or PMD is a bilateral (both eyes), non-inflammatory corneal disease characterized by severe inferior crescent shaped thinning. Often times this condition is confused with Keratoconus and shares many of its characteristics and prognosis.

Is pellucid marginal degeneration hereditary?

Although most cases of KC are considered sporadic, hereditary associations have been found.In contrast to KC, Pellucid Marginal Degeneration (PMD) is less common and is distinguished by a band of thinning of the inferior cornea and corneal protrusion superior to this band.

Can pellucid marginal degeneration cause blindness?

It usually affects both eyes, although one eye can be worse than the other. Although no one can be sure how severe the keratoconus will be in an individual, the condition does not cause blindness. With current management options available most patients should be able to lead a normal lifestyle.

What is the difference between keratoconus and Keratoglobus?

Keratoconus is different from keratoglobus in the age of presentation. Whereas keratoglobus presents at birth, keratoconus develops around puberty and may progress until 40–50 years of age. Keratoglobus is considered a non-progressive or minimally progressive disorder.

What is the difference between degeneration and dystrophy?

Degenerations are usually unilateral, asymmetric and often peripheral. Changes caused by inflammation, maturity or systemic disease result in deposition, thinning or vascularization of the corneal tissue. Dystrophies are rare conditions and may not present in a primary setting.

What is Fuchs dystrophy?

Fuchs' dystrophy; Fuchs' endothelial dystrophy; Fuchs' corneal dystrophy. Fuchs (pronounced "fooks") dystrophy is an eye disease in which cells lining the inner surface of the cornea slowly start to die off. The disease most often affects both eyes.
