T70.2 — Other and unspecified effects of high altitude
T70.2 is a non-billable header ICD-10-CM code for other and unspecified effects of high altitude. 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
- A
- initial encounter
- D
- subsequent encounter
- S
- sequela
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.
- polycythemia due to high altitude (D75.1)
Other codes that can never be billed with T70.2
These codes carry an Excludes1 note pointing at T70.2. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading T70.2 alone.
- T71Asphyxiation
Risk adjustment
T70.2 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.
Code to one of these instead T70.2
