B90.9Sequelae of respiratory and unspecified tuberculosis

B90.9 is the ICD-10-CM diagnosis code for sequelae of respiratory and unspecified tuberculosis. It belongs to category B90 (sequelae of tuberculosis), block B90-B94 (sequelae of infectious and parasitic diseases) and chapter 1 (certain infectious and parasitic diseases). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within B90, choose B90.9 (respiratory and unspecified tuberculosis) only when documentation doesn't support a more specific option: central nervous system tuberculosis (B90.0), genitourinary tuberculosis (B90.1), of bones and joints (B90.2) and of other organs (B90.8).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 196 (Interstitial Lung Disease with MCC, relative weight 1.8336), DRG 197 (Interstitial Lung Disease with CC, relative weight 0.9492) and DRG 198 (Interstitial Lung Disease without CC/MCC, relative weight 0.7259), in MDC 04 (Diseases and Disorders of the Respiratory System), 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 is exempt from present-on-admission (POA) reporting, so no POA indicator is required.

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 137.0 (late effects of respiratory or unspecified tuberculosis).
