T70.0 — Otitic barotrauma
T70.0 is a non-billable header ICD-10-CM code for otitic barotrauma. 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.
This code requires a 7th character
The appropriate 7th character is to be added to each code from category T70

Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Aero-otitis media
- Effects of change in ambient atmospheric pressure or water pressure on ears
Other codes that can never be billed with T70.0
These codes carry an Excludes1 note pointing at T70.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading T70.0 alone.
- H65.1Other acute nonsuppurative otitis media
Risk adjustment
T70.0 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 T70.0 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 T70.0.
