T38.8 — Poisoning by, adverse effect of and underdosing of other and unspecified hormones and synthetic substitutes
T38.8 is a non-billable header ICD-10-CM code for poisoning by, adverse effect of and underdosing of other and unspecified hormones and synthetic substitutes. 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.

Other codes that can never be billed with T38.8
These codes carry an Excludes1 note pointing at T38.8. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading T38.8 alone.
- T48.6Poisoning by, adverse effect of and underdosing of antiasthmatics, not elsewhere classified
Risk adjustment
T38.8 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.
