K22.1 — Ulcer of esophagus

Not billable

Is K22.1 billable?

No — K22.1 is a non-billable header code. K22.1 groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 2 billable codes beneath K22.1.

Excludes1 — never code together

The conditions below can never be reported together with K22.1 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

Code first

The underlying condition below must be sequenced before K22.1. K22.1 describes a manifestation and cannot be the principal or first-listed diagnosis.

  • poisoning due to drug or toxin, if applicable (T36-T65 with fifth or sixth character 1-4)

Use additional code

Report an additional code alongside K22.1 to fully describe the condition. K22.1 is sequenced first.

  • code for adverse effect, if applicable, to identify drug (T36-T50 with fifth or sixth character 5)
