ICD-10-CM Code H11.143: Conjunctival xerosis, unspecified, bilateral

ICD-10-CM code H11.143 represents conjunctival xerosis, unspecified, bilateral, classified as a Disease or Syndrome. The code is an active terminology concept with a parent category of H11.14. Clinical literature associates conjunctival xerosis with vitamin A deficiency and related ocular surface complications. 1 2

Plain-language overview

Code H11.143 identifies a diagnosis of conjunctival xerosis that is unspecified and affects both eyes, serving as an active terminology record for this specific ocular condition. 1

What this code represents

The concept H11.143 is categorized with the semantic type of Disease or Syndrome and is nested under the parent concept H11.14 for unspecified conjunctival xerosis. 1

The terminology record for H11.143 indicates that this active diagnosis code possesses narrower concepts within the ICD-10-CM hierarchy, establishing its position as a broader category. 1

Clinical context

Clinical literature identifies conjunctival xerosis as an ocular surface complication attributed to a deficiency of retinoic acid, which plays a critical role in epithelial cell maintenance. 2

In documented clinical cases, conjunctival xerosis appears alongside other ocular findings including Bitot's spots, superficial punctate keratitis, and nyctalopia. 2

Documentation considerations

The official terminology record establishes bilateral involvement and an unspecified clinical status as the defining diagnostic elements for the H11.143 code. 1

What the sources add

While the terminology record defines the code structure, clinical case literature provides operational context by linking conjunctival xerosis to vitamin A deficiency and retinoic acid depletion. 1 2

A separate phecode mapping resource lists conjunctival xerosis with an unspecified eye designation, distinguishing it from the bilateral specificity established for code H11.143. 1 3

Two distinct official terminology platforms confirm the identical code, preferred name, and Disease semantic type for H11.143, reinforcing the validity of the diagnostic label. 1 4
