J84.1 — Other interstitial pulmonary diseases with fibrosis
Is J84.1 billable?
No — J84.1 is a non-billable header code. J84.1 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 10 billable codes beneath J84.1.

Excludes1 — never code together
The conditions below can never be reported together with J84.1 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- pulmonary fibrosis (chronic) following radiation (J70.1)
Code also
Two codes may be needed to describe the condition fully. Whether J84.1 is sequenced first depends on the reason for the encounter.
- , if applicable, pulmonary fibrosis (chronic) due to inhalation of chemicals, gases, fumes or vapors (J68.4)
Excludes1 — never code together — inherited from J84
The conditions below can never be reported together with J84.1 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
Use additional code — inherited from Chapter 10
Report an additional code alongside J84.1 to fully describe the condition. J84.1 is sequenced first.
Excludes2 — not included here — inherited from Chapter 10
The conditions below are not part of J84.1, but a patient may have both at the same time. When documentation supports it, J84.1 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)
Excludes2 — not included here — inherited from J84
The conditions below are not part of J84.1, but a patient may have both at the same time. When documentation supports it, J84.1 and the excluded code may both be reported.
- lung diseases due to external agents (J60-J70)
Code also — inherited from J84
Two codes may be needed to describe the condition fully. Whether J84.1 is sequenced first depends on the reason for the encounter.

What codes fall under J84.1? (3)
How long has J84.1 existed?
J84.1 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 J84.1?
ICD-10-CM declares these codes mutually exclusive with J84.1 — exactly one of each pair can be correct for a given encounter.
