J84: Other interstitial pulmonary diseases

Non-billable headerICD-10-CM

J84 is a non-billable header ICD-10-CM code for other interstitial pulmonary diseases. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1: never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

  • drug-induced interstitial lung disorders (J70.2-J70.4)
  • interstitial emphysema (J98.2)

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.

  • lung diseases due to external agents (J60-J70)

Code also

Both codes may be needed to describe the encounter fully. Sequencing depends on the reason for the visit.

  • , if applicable, associated condition
