- Billable — Valid for Submission
- CC — Complication or Comorbidity
- Not Chronic
J82.89 is a billable ICD-10-CM diagnosis code for other pulmonary eosinophilia, not elsewhere classified. 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 allergic bronchopulmonary mycosis. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Other specified and unspecified lower respiratory disease.
J82.89 no longer risk-adjusts for Medicare Advantage: it mapped to HCC 112 under the retired CMS-HCC V24 model through payment year 2025 but maps to no category in the live V28 model. It still risk-adjusts in the PACE (CMS-HCC V22) category 112, ESRD (V21) category 112, and ESRD (V24) category 112 for payment year 2027.

Notes
General instructions on how these codes are used.
- 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).

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
Eosinophilic Disorders
Eosinophils are a type of white blood cell. They help fight off infections and play a role in your body's immune response. They can also build up and cause inflammation.

Questions About J82.89Overview
What is the ICD-10 code for other pulmonary eosinophilia, not elsewhere classified?
The ICD-10-CM code for other pulmonary eosinophilia, not elsewhere classified is J82.89 (sometimes written as J8289). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is J82.89 (Pulmonary eosinophilia, not elsewhere classified) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report other pulmonary eosinophilia, not elsewhere classified on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does J82.89 group to?
When other pulmonary eosinophilia, not elsewhere classified 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 J82.89 a CC or MCC?
CMS lists J82.89 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.
Does J82.89 risk-adjust for Medicare Advantage payment?
Not for Medicare Advantage. J82.89 mapped to HCC 112 in the retired CMS-HCC V24 model, which last determined payment in 2025, but it maps to no category in the live V28 model; see all codes that no longer risk-adjust. It still risk-adjusts in the PACE (CMS-HCC V22) category 112 (Fibrosis of Lung and Other Chronic Lung Disorders), ESRD (V21) category 112 (Fibrosis of Lung and Other Chronic Lung Disorders), and ESRD (V24) category 112 (Fibrosis of Lung and Other Chronic Lung Disorders).
