What This Code Means
L75.9 is the ICD-10-CM diagnosis code for apocrine sweat disorder, unspecified. An unspecified disorder of the apocrine sweat glands when the exact type of problem cannot be determined. L75.9 sits in the ICD-10-CM chapter for diseases of the skin and subcutaneous tissue (l00-l99), within the section covering disorders of skin appendages (l60-l75).
L75.9 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.
This is a last-resort code; query the provider if more specific information about the apocrine sweat disorder is available.
HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for L75.9 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
