T48.6 — Poisoning by, adverse effect of and underdosing of antiasthmatics, not elsewhere classified
T48.6 is a non-billable header ICD-10-CM code for poisoning by, adverse effect of and underdosing of antiasthmatics, not elsewhere classified. 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 T48
- A
- initial encounter
- D
- subsequent encounter
- S
- sequela
Excludes1 — never code together
These conditions cannot occur together. Billing both on the same encounter is a denial.
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Poisoning by, adverse effect of and underdosing of beta-adrenoreceptor agonists used in asthma therapy
Other codes that can never be billed with T48.6
These codes carry an Excludes1 note pointing at T48.6. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading T48.6 alone.
- T44.5Poisoning by, adverse effect of and underdosing of predominantly beta-adrenoreceptor agonists
Risk adjustment
T48.6 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 T48.6
1 child code. Green means billable.
