About coding tuberculosis sequelae
The ICD-10-CM code for tuberculosis sequelae is B90.9 (Sequelae of respiratory and unspecified tuberculosis). The official index lists 5 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on B90.9.
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.
