What This Code Means
H44.322 is the ICD-10-CM diagnosis code for siderosis of eye, left eye. Siderosis of the left eye is a condition where iron deposits accumulate in the eye tissues, typically from an iron-containing foreign body or occupational exposure. This can cause discoloration and potentially damage the eye's structures over time. H44.322 sits in the ICD-10-CM chapter for diseases of the eye and adnexa (h00-h59), within the section covering disorders of vitreous body and globe (h43-h44).
H44.322 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.
Verify laterality is documented as left eye (H44.322) and not bilateral or right eye, as laterality is required for accurate coding.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for H44.322 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Verify laterality is documented as left eye (H44.322) and not bilateral or right eye, as laterality is required for accurate coding
- •Look for documentation of the cause (foreign body, occupational exposure) as this may require an additional external cause code (W-code) for proper documentation
