J95.821Acute postprocedural respiratory failure

J95.821 is the ICD-10-CM diagnosis code for acute postprocedural respiratory failure. It belongs to category J95 (intraoperative and postprocedural complications and disorders of respiratory system, not elsewhere classified), block J95 (intraoperative and postprocedural complications and disorders of respiratory system, not elsewhere classified) and chapter 10 (diseases of the respiratory system). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within J95.82 (postprocedural respiratory failure), J95.821 is specifically for acute postprocedural respiratory failure. Related codes cover and chronic postprocedural respiratory failure (J95.822).

As a secondary diagnosis it is an MCC (major complication or comorbidity), which can move an inpatient stay into the highest-paying "with MCC" MS-DRG of its family, unless the principal diagnosis excludes it.

In MS-DRG v44.0, it is part of the grouping logic for DRG 189 (Pulmonary Edema and Respiratory Failure, relative weight 1.2108), DRG 928 (Full Thickness Burn with Skin Graft or Inhalation Injury with CC/MCC, relative weight 7.6477), DRG 929 (Full Thickness Burn with Skin Graft or Inhalation Injury without CC/MCC, relative weight 3.0193) and DRG 934 (Full Thickness Burn without Skin Graft or Inhalation Injury, relative weight 1.9895), in MDC 04 (Diseases and Disorders of the Respiratory System) and MDC 22 (Burns), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 518.51 (acute respiratory failure following trauma and surgery).
