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

J95.811 is a billable ICD-10-CM diagnosis code for postprocedural pneumothorax. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 199 through 201. 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 18 closely related codes. Coders also document this condition as iatrogenic pneumothorax. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Pneumothorax and Postprocedural or postoperative respiratory system complication.

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).

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.

What is the ICD-10 code for postprocedural pneumothorax?

The ICD-10-CM code for postprocedural pneumothorax is J95.811 (sometimes written as J95811). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

Is J95.811 (Postprocedural pneumothorax and air leak) a billable code?

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

What MS-DRG does J95.811 group to?

When postprocedural pneumothorax is the principal diagnosis on an inpatient stay, it groups to MS-DRG 201, 199, 200, with relative weights from 0.6782 to 1.7314 depending on complications. Higher weights mean higher Medicare reimbursement.

Is J95.811 a CC or MCC?

CMS lists J95.811 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 18 closely related codes in its exclusion list.

What is the ICD-9 equivalent of J95.811?

Under the General Equivalence Mappings, postprocedural pneumothorax converts to ICD-9-CM 512.1 (iatrogenic pneumothorax). The mapping is approximate, so confirm the match fits the documentation.
