What This Code Means
L85.1 is the ICD-10-CM diagnosis code for acquired keratosis [keratoderma] palmaris et plantaris. A condition where the skin on the palms and soles becomes abnormally thick and hardened, usually acquired over time rather than present from birth. L85.1 sits in the ICD-10-CM chapter for diseases of the skin and subcutaneous tissue (l00-l99), within the section covering other disorders of the skin and subcutaneous tissue (l80-l99).
L85.1 is a billable ICD-10-CM code, but the current payload does not show a mapping under the CMS-HCC V28, V24, ESRD, or RxHCC models. Do not assign risk adjustment value from this page when no source-backed mapping is shown; verify the applicable model and payment year.
Verify whether this is acquired or congenital; congenital cases may require a different code.
HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for L85.1 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Verify whether this is acquired or congenital; congenital cases may require a different code
- •Document the extent and severity of thickening to support medical necessity for treatment
Excludes 1, Do NOT code together
- inherited keratosis palmaris et plantaris (Q82.8)
