Sepsis due to streptococcus, group B

BILLABLE STATUSYes

Code Description

ICD-10 A40.1 is a billable code used to indicate a diagnosis of sepsis due to streptococcus, group b.

Key Diagnostic Point:

Sepsis due to Group B Streptococcus (GBS) is a severe systemic infection that arises from the presence of GBS bacteria in the bloodstream. This condition is particularly concerning in vulnerable populations, including newborns, pregnant women, and the elderly. GBS can lead to significant morbidity and mortality if not promptly recognized and treated. Clinically, patients may present with fever, chills, tachycardia, hypotension, and altered mental status, indicating a systemic inflammatory response. The diagnosis of sepsis necessitates a high index of suspicion, especially in at-risk populations. Laboratory tests typically reveal elevated white blood cell counts, positive blood cultures for GBS, and other markers of infection. Management involves aggressive fluid resuscitation, broad-spectrum antibiotics, and supportive care, often requiring intensive care unit (ICU) admission for severe cases. Antimicrobial stewardship is critical in managing GBS sepsis to prevent antibiotic resistance and ensure effective treatment. Early identification and intervention are key to improving outcomes in patients with this life-threatening condition.

Coding Guidelines

Inclusion Criteria

Use A40.1 When
  • According to ICD
  • 10 guidelines, A40
  • 1 should be used when the sepsis is specifically due to Group B Streptococcus
  • It is essential to document the presence of sepsis and the causative organism clearly

Exclusion Criteria

Do NOT use A40.1 When
  • Exclusion criteria include cases where the infection is not confirmed or where another organism is identified as the cause

Initial hospital care, typically 50 minutes or more

Clinical Scenario

Used for the initial evaluation and management of a patient with sepsis in the hospital setting.

Documentation Requirements

Detailed history, examination, and medical decision-making must be documented.

Specialty Considerations

Critical care specialists should ensure that all elements of care are documented to support the level of service billed.

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more precise coding of infections, including sepsis due to specific organisms like Group B Streptococcus. This specificity aids in better tracking of infection rates and outcomes, ultimately improving patient care and resource allocation.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more precise coding of infections, including sepsis due to specific organisms like Group B Streptococcus. This specificity aids in better tracking of infection rates and outcomes, ultimately improving patient care and resource allocation.
