Non-billable headerICD-10-CM

T48.0 is a non-billable header ICD-10-CM code for poisoning by, adverse effect of and underdosing of oxytocic drugs. 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.

  • poisoning by, adverse effect of and underdosing of estrogens, progestogens and antagonists (T38.4-T38.6)

Other codes that can never be billed with T48.0

These codes carry an Excludes1 note pointing at T48.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading T48.0 alone.

  • T38Poisoning by, adverse effect of and underdosing of hormones and their synthetic substitutes and antagonists, not elsewhere classified
  • T44.6Poisoning by, adverse effect of and underdosing of alpha-adrenoreceptor antagonists

Risk adjustment

T48.0 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.

Code to one of these instead T48.0

1 child code. Green means billable.
