What This Code Means
D31.52 is the ICD-10-CM diagnosis code for benign neoplasm of left lacrimal gland and duct. A non-cancerous tumor that develops in the lacrimal gland or duct on the left side of the eye, which are structures responsible for producing tears. This condition is benign, meaning it does not spread to other parts of the body. D31.52 sits in the ICD-10-CM chapter for neoplasms (c00-d49), within the section covering benign neoplasms, except benign neuroendocrine tumors (d10-d36).
D31.52 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.
Ensure laterality is correctly documented as left (52) versus right (51) or unspecified (50) to avoid claim denials.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for D31.52 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Ensure laterality is correctly documented as left (52) versus right (51) or unspecified (50) to avoid claim denials
- •Verify that imaging or pathology reports confirm the benign nature of the neoplasm before coding, as malignant lacrimal gland tumors use different codes (C69.5-)
