X52 — Prolonged stay in weightless environment
X52 is a non-billable header ICD-10-CM code for prolonged stay in weightless environment. It cannot be billed on its own: choose one of the more specific child codes below. This code also requires a 7th character before it is complete.

Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Weightlessness in spacecraft (simulator)
Risk adjustment
X52 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 X52 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 X52.
- Weightlessness(causing injury) (effects of) (in spacecraft, real or simulated)
- Prolonged›stay in›weightless environment
Code to one of these instead X52
3 child codes. Green means billable.
