ICD-10-CM J98.19
CMSSource: CMS FY 2027 ICD-10-CM dataset · Effective Oct 1, 2026 – Sep 30, 2027

J98.19 is a billable ICD-10-CM diagnosis code for other pulmonary collapse. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 205 through 206, 791, 793. 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 10 closely related codes. Coders also document this condition as bulla of lung. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Pleurisy, pleural effusion and pulmonary collapse.

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to J98.19: its own notes plus those printed at J98.1, J98, and Chapter 10. A note printed at a category, block or chapter applies to every code under it.

Excludes1

Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.

From J98.1 Pulmonary collapse applies to 2 codes
  • therapeutic collapse of lung status (Z98.3)

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.

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).

Clinical InformationClinical

  • Middle Lobe Syndrome

    atelectasis of the right middle pulmonary lobe, with chronic pneumonitis. (dorland, 27th ed)

Patient EducationClinical

Collapsed Lung

A collapsed lung happens when air enters the pleural space, the area between the lung and the chest wall. If it is a total collapse, it is called pneumothorax. If only part of the lung is affected, it is called atelectasis.

Questions About J98.19Overview

What is the ICD-10 code for other pulmonary collapse?

The ICD-10-CM code for other pulmonary collapse is J98.19 (sometimes written as J9819). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

Is J98.19 (Pulmonary collapse) a billable code?

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

What MS-DRG does J98.19 group to?

When other pulmonary collapse is the principal diagnosis on an inpatient stay, it groups to MS-DRG 793, 791, 206, 205, with relative weights from 0.9255 to 4.2192 depending on complications. Higher weights mean higher Medicare reimbursement.

Is J98.19 a CC or MCC?

CMS lists J98.19 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 10 closely related codes in its exclusion list.

Can J98.19 be reported with Z98.3?

Not as a rule. The Excludes1 note at J98.1, which applies to J98.19, lists "therapeutic collapse of lung status (Z98.3)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
