H18.319 ICD-10-CM Code: Folds and rupture in Bowman's membrane, unspecified eye

H18.319 is the ICD-10-CM diagnosis code for folds and rupture in bowman's membrane, unspecified eye. This code describes damage to Bowman's membrane, a thin layer in the front part of the eye, where folds or tears have developed but the specific eye affected is not documented. This condition can affect vision and may result from injury, disease, or degenerative changes. H18.319 sits in the ICD-10-CM chapter for diseases of the eye and adnexa (h00-h59), within the section covering disorders of sclera, cornea, iris and ciliary body (h15-h22).

H18.319 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.

If the affected eye is documented (right, left, or bilateral), use the more specific codes H18.311, H18.312, or H18.313 instead of the unspecified code H18.319.
