E88.1

E88.1 — Lipodystrophy, not elsewhere classified

Non-billable headerICD-10-CM

E88.1 is a non-billable header ICD-10-CM code for lipodystrophy, not elsewhere classified. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

Whipple's disease (K90.81)

Excludes1 inherited from the categories above E88.1

These are not written on E88.1, but they bind it: a note on a category applies to every code beneath it. Billing E88.1 with anything listed here is a denial.

Written on E88 — Other and unspecified metabolic disorders

histiocytosis X (chronic) (C96.6)

Risk adjustment

E88.1 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
