Which MS-DRGs does J84.841 group to?

J84.841 sits in MDC 04 and helps define the logic of 3 MS-DRGs (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.

  • 196Interstitial Lung Disease with MCCmedical
  • 197Interstitial Lung Disease with CCmedical
  • 198Interstitial Lung Disease without CC/MCCmedical

As a secondary diagnosis, J84.841 is a major complication or comorbidity (MCC), which can move a stay into a higher-paying DRG.

How is J84.841 listed in the Alphabetic Index?

These are the routes through the Alphabetic Index that lead to J84.841. They show the wording a clinician may have documented, which often differs from the Tabular description.

  • Hyperplasia, hyperplasticneuroendocrine cell, of infancy

Excludes1 — never code together — inherited from J84

The conditions below can never be reported together with J84.841 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

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

Excludes1 — never code together — inherited from J84.8

The conditions below can never be reported together with J84.841 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • exogenous lipoid pneumonia (J69.1)
  • unspecified lipoid pneumonia (J69.1)

Use additional code — inherited from Chapter 10

Report an additional code alongside J84.841 to fully describe the condition. J84.841 is sequenced first.

  • code, where applicable, to identify:
  • exposure to environmental tobacco smoke (Z77.22)
  • exposure to tobacco smoke in the perinatal period (P96.81)
  • history of tobacco dependence (Z87.891)
  • occupational exposure to environmental tobacco smoke (Z57.31)
  • tobacco dependence (F17.-)
  • tobacco use (Z72.0)

Excludes2 — not included here — inherited from Chapter 10

The conditions below are not part of J84.841, but a patient may have both at the same time. When documentation supports it, J84.841 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 J84.841, but a patient may have both at the same time. When documentation supports it, J84.841 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 J84.841 is sequenced first depends on the reason for the encounter.

How long has J84.841 existed?

J84.841 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.
