J84 — Other interstitial pulmonary diseases
Is J84 billable?
No — J84 is a non-billable header code. J84 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 24 billable codes beneath J84.

Excludes1 — never code together
The conditions below can never be reported together with J84 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
Excludes2 — not included here
The conditions below are not part of J84, but a patient may have both at the same time. When documentation supports it, J84 and the excluded code may both be reported.
- lung diseases due to external agents (J60-J70)
Code also
Two codes may be needed to describe the condition fully. Whether J84 is sequenced first depends on the reason for the encounter.
- , if applicable, associated condition
Use additional code — inherited from Chapter 10
Report an additional code alongside J84 to fully describe the condition. J84 is sequenced first.
Excludes2 — not included here — inherited from Chapter 10
The conditions below are not part of J84, but a patient may have both at the same time. When documentation supports it, J84 and the excluded code may both be reported.
- certain conditions originating in the perinatal period (P04-P96)
- certain infectious and parasitic diseases (A00-B99)
- complications of pregnancy, childbirth and the puerperium (O00-O9A)
- congenital malformations, deformations and chromosomal abnormalities (Q00-Q99)
- endocrine, nutritional and metabolic diseases (E00-E88)
- injury, poisoning and certain other consequences of external causes (S00-T88)
- neoplasms (C00-D49)
- smoke inhalation (T59.81-)
- symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (R00-R94)
What codes fall under J84? (5)
How long has J84 existed?
J84 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
Which codes are confused with J84?
ICD-10-CM declares these codes mutually exclusive with J84 — exactly one of each pair can be correct for a given encounter.
