ICD-10-CM J82.83
CMSSource: CMS FY 2027 ICD-10-CM dataset · Effective Oct 1, 2026 – Sep 30, 2027

J82.83 is a billable ICD-10-CM diagnosis code for eosinophilic asthma. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 196 through 198. As a secondary diagnosis, it counts as a complication or comorbidity (CC) and moves an inpatient stay to a higher severity level within its MS-DRG family. It does not count, however, when the principal diagnosis is one of 4 closely related codes. Coders also document this condition as asthmatic pulmonary eosinophilia. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Other specified and unspecified lower respiratory disease.

J82.83 does not risk-adjust for Medicare Advantage under the CMS-HCC V28 model. It still risk-adjusts in the RxHCC Part D (V08) category 229 for payment year 2027.

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to J82.83: its own notes plus those printed at J82 and Chapter 10. A note printed at a category, block or chapter applies to every code under it.

Excludes2

Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.

From J82 Pulmonary eosinophilia, not elsewhere classified applies to 4 codes
  • pulmonary eosinophilia due to aspergillosis (B44.-)
  • pulmonary eosinophilia due to drugs (J70.2-J70.4)
  • pulmonary eosinophilia due to specified parasitic infection (B50-B83)
  • pulmonary eosinophilia due to systemic connective tissue disorders (M30-M36)
  • pulmonary infiltrate NOS (R91.8)
From Chapter 10 (J00-J99) Diseases of the respiratory system applies to 366 codes
  • 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)

Code First

The underlying condition named in the note is sequenced before this code.

  • asthma, by type, such as:
  • mild intermittent asthma (J45.2-)
  • mild persistent asthma (J45.3-)
  • moderate persistent asthma (J45.4-)
  • severe persistent asthma (J45.5-)

Use Additional Code

Add a second code, after this one, to fully describe the condition.

From Chapter 10 (J00-J99) Diseases of the respiratory system applies to 366 codes
  • 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)

Notes

General instructions on how these codes are used.

From Chapter 10 (J00-J99) Diseases of the respiratory system applies to 366 codes
  • When a respiratory condition is described as occurring in more than one site and is not specifically indexed, it should be classified to the lower anatomic site (e.g. tracheobronchitis to bronchitis in J40).

Excludes2 2

These codes carry an Excludes2 note naming J82.83: its condition is not part of those codes, and both may be reported when the patient has both.

  • D72.1 Eosinophilia
    pulmonary eosinophilia (J82.-) names J82.-, which includes this code
  • Block J09-J18 Influenza and pneumonia
    allergic or eosinophilic pneumonia (J82) names J82, which includes this code

Use Additional Code 1

Clinical InformationClinical

  • Pulmonary Eosinophilia

    a condition characterized by infiltration of the lung with eosinophils due to inflammation or other disease processes. major eosinophilic lung diseases are the eosinophilic pneumonias caused by infections, allergens, or toxic agents.

Patient EducationClinical

Asthma

Asthma is a chronic (long-term) lung disease. It affects your airways, the tubes that carry air in and out of your lungs. When you have asthma, your airways can become inflamed and narrowed. This can cause wheezing, coughing, and tightness in your chest. When these symptoms get worse than usual, it is called an asthma attack or flare-up.

Questions About J82.83Overview

What is the ICD-10 code for eosinophilic asthma?

The ICD-10-CM code for eosinophilic asthma is J82.83 (sometimes written as J8283). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

Is J82.83 (Pulmonary eosinophilia, not elsewhere classified) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report eosinophilic asthma on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What MS-DRG does J82.83 group to?

When eosinophilic asthma is the principal diagnosis on an inpatient stay, it groups to MS-DRG 198, 197, 196, with relative weights from 0.7256 to 1.8335 depending on complications. Higher weights mean higher Medicare reimbursement.

Is J82.83 a CC or MCC?

CMS lists J82.83 as a CC (complication or comorbidity) for FY 2027. Reported as a secondary diagnosis, it moves the inpatient stay to a higher-weighted DRG within its severity family. It does not count when the principal diagnosis is one of the 4 closely related codes in its exclusion list.

What is coded first with J82.83?

The Code First note reads: asthma, by type, such as: mild intermittent asthma (J45.2-); mild persistent asthma (J45.3-); moderate persistent asthma (J45.4-); severe persistent asthma (J45.5-). When one of these applies, it is sequenced before J82.83.

Does J82.83 risk-adjust for Medicare Advantage payment?

Not for Medicare Advantage: J82.83 maps to no category in the CMS-HCC V28 model. It still risk-adjusts in the RxHCC Part D (V08) category 229 (Chronic Obstructive Pulmonary Disease, Bronchiectasis, and Other Asthma).
