What This Code Means
H30.819 is the ICD-10-CM diagnosis code for harada's disease, unspecified eye. Harada's disease is a rare inflammatory condition that affects the eye and causes swelling of the uvea (the middle layer of the eye), leading to vision problems and eye pain. This code indicates the condition is present but the specific eye affected is not documented. H30.819 sits in the ICD-10-CM chapter for diseases of the eye and adnexa (h00-h59), within the section covering disorders of choroid and retina (h30-h36).
H30.819 is a billable ICD-10-CM code, but the current payload does not show a mapping under the CMS-HCC V28 or V24 community payment models, and none under the ESRD, Part D RxHCC, or HHS-HCC models. Do not assign risk adjustment value from this page when no source-backed mapping is shown; verify the applicable model and payment year.
Always attempt to determine laterality (right eye, left eye, or bilateral) from clinical documentation to use more specific codes (H30.811 for right eye, H30.812 for left eye, H30.813 for bilateral) rather than the unspecified code.
HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for H30.819 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Always attempt to determine laterality (right eye, left eye, or bilateral) from clinical documentation to use more specific codes (H30.811 for right eye, H30.812 for left eye, H30.813 for bilateral) rather than the unspecified code
- •Harada's disease is often associated with systemic symptoms; review documentation for concurrent conditions like meningitis or hearing loss that may require additional coding
