About coding cornea deposit
The ICD-10-CM code for cornea deposit is H18.00 (Unspecified corneal deposit). The official index lists 3 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on H18.00.
Within H18.0, choose H18.00 (Unspecified corneal deposit) only when documentation doesn't support a more specific option: anterior corneal pigmentations (H18.01), Argentous corneal deposits (H18.02), corneal deposits in metabolic disorders (H18.03), Kayser-Fleischer ring (H18.04), posterior corneal pigmentations (H18.05) and stromal corneal pigmentations (H18.06).
To report this condition, pick the subcode that matches the documentation: H18.001 (right eye), H18.002 (left eye), H18.003 (bilateral) and H18.009 (unspecified eye).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
