Answer 1

Persons with latent TB infection do not feel sick and do not have any symptoms.They are infected with M.tuberculosis,but do not have TB disease.The only sign of TB infection is a positive reaction to the tuberculin skin test or TB blood test.

ICD - 10 - CM Code for latent TB Infection is Z22.7 “ Carrier of latent tuberculosis” which includes a previous positive test for TB infection without evidence of disease,but excludes :

• ” nonspecific reaction to cell-mediated immunity measurement of gamma interferon antigen response without active tuberculosis”(R76.12)and
• ” nonspecific reaction to tuberculin skin test without active tuberculosis”(R76.11)

ICD - 10-CM Code for disorders of skin and subcutaneous tissue unspecis L98.9
