E88.A — Wasting disease (syndrome) due to underlying condition
E88.A is a billable, specific ICD-10-CM code for wasting disease (syndrome) due to underlying condition. It is valid for submission on a claim.
Excludes1 — never code together
These conditions cannot occur together. Billing both on the same encounter is a denial.
Excludes2 — not included here, but may coexist
The excluded condition is not part of this code, but a patient can have both. You may code both.
Code first
The underlying condition must be sequenced before this code.
- underlying condition
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Cachexia due to underlying condition
Other codes that can never be billed with E88.A
These codes carry an Excludes1 note pointing at E88.A. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading E88.A alone.
- R64Cachexia
Risk adjustment
E88.A 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.
How E88.A is indexed
Coders do not find codes by browsing the tabular list — they look them up in the alphabetic index, under the word the physician wrote. These are the index entries that lead here, so you can see which chart wordings map to E88.A.
