T39 — Poisoning by, adverse effect of and underdosing of nonopioid analgesics, antipyretics and antirheumatics
T39 is a non-billable header ICD-10-CM code for poisoning by, adverse effect of and underdosing of nonopioid analgesics, antipyretics and antirheumatics. 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 T39
- A
- initial encounter
- D
- subsequent encounter
- S
- sequela
Other codes that can never be billed with T39
These codes carry an Excludes1 note pointing at T39. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading T39 alone.
- T39.4Poisoning by, adverse effect of and underdosing of antirheumatics, not elsewhere classified
Risk adjustment
T39 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.
