T88.1: Other complications following immunization, not elsewhere classified

Non-billable headerICD-10-CM

T88.1 is a non-billable header ICD-10-CM code for other complications following immunization, 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 T88

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.

vaccinia not from vaccine (B08.011)

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.

anaphylactic shock due to serum (T80.5-)
other serum reactions (T80.6-)
postimmunization arthropathy (M02.2)
postimmunization encephalitis (G04.02)
postimmunization fever (R50.83)

Inclusion terms

Alternative wordings a physician may use in the chart for this same code.

Generalized vaccinia
Rash following immunization

Excludes2 inherited from the categories above T88.1

Not part of this code, but both may be coded when both are present.
