ICD-10 Code B90: Sequelae of tuberculosis
Reviewed by HealthAssure Clinical TeamUpdated 21 May 2026
What is this code?
ICD-10 entries help standardize how diagnoses are organized for coding, reporting, analytics, and documentation. This code sits within the broader ICD-10 area for Certain infectious and parasitic diseases (A00-B99).
đź“‹Clinical overview
This ICD-10 code is commonly used when documentation describes sequelae of prior tuberculosis. The most accurate code depends on whether the lasting residual effects involve the central nervous system, genitourinary system, bones and joints, other organs, or respiratory and unspecified tuberculosis patterns.
When is it used?
- May be used when a clinician documents sequelae of tuberculosis in a patient's medical record.
- May appear in hospital records, claims, referrals, and clinical documentation.
- This code may act more like a grouping or parent code, so a more specific child code may be used in final documentation when available.
What it does not mean
- A code alone does not explain severity, treatment plan, or outcome.
- A medical code should not be treated as a substitute for a doctor's diagnosis or advice.
- This entry may represent a broader category rather than the most specific billable code.
đź©şClinical context
When commonly used
- Primary-care, infectious-disease, pulmonary, neurology, urology, orthopedics, rehabilitation, and follow-up documentation where long-term effects of prior tuberculosis remain clinically relevant after active infection has resolved.
- Coding and utilization-review workflows where the chart distinguishes residual site-specific tuberculosis sequelae from active tuberculosis and that distinction changes final code specificity.
Common management context
- Sequelae-of-tuberculosis follow-up often includes review of prior tuberculosis history, residual organ dysfunction, imaging or functional monitoring, symptom management, and specialty follow-up based on the body system affected by the lasting sequelae.
- Documentation usually becomes more specific when the chart identifies the residual organ system more clearly rather than using a broad post-tuberculosis sequelae label.
- Specialist context already linked on this page includes Infectious Disease Specialist, General Physician.
🔍Key distinctions
Important notes
- This ICD-10 family captures residual long-term effects of prior tuberculosis rather than current active tuberculosis disease.
- Residual site detail matters here, because central nervous system, genitourinary, musculoskeletal, other-organ, and respiratory tuberculosis sequelae are coded separately when documented.
- This parent page groups residual conditions left after prior tuberculosis, so the final billable code usually depends on whether the lasting sequelae involve the central nervous system, genitourinary system, bones and joints, other organs, or respiratory and unspecified tuberculosis patterns.
- Documentation that describes sequelae of tuberculosis is coded differently from active tuberculosis because this family captures residual long-term effects after prior infection rather than current active disease.
