Coverage Criteria — Medical Necessity and Levels of Care

Medical necessity criteria for level of care and discharge

Management is medically necessary at the indicated level of care when the following criteria are met:

Episode Day 1 — Well-appearing infants: Well-appearing infants who are on 48 hours of antibiotics pending blood culture results are appropriate for level II nursery (rev code 172).

Episode Day 1 — Symptomatic infants

a: Signs of neonatal sepsis (examples: hypotonia, lethargy, poor oral feeding, tachycardia, bradycardia, grunting, nasal flaring, cyanosis).
b: Temperature ≥ 100.4 °F or ≤ 96.8 °F (≥ 38.0 °C or ≤ 36.0 °C).≥ 100.4 °F or ≤ 96.8 °F
c: On 48 hours of antibiotics pending blood culture results or receiving treatment for positive blood cultures.48 hours

Episode Day 2 and subsequent days — negative cultures requiring antibiotics: Infants with negative cultures who require antibiotics beyond 48 hours may be appropriate for transitional care or level I nursery (rev code 171) once antibiotics are the only intervention necessitating continued stay and outpatient antibiotics are inappropriate or unmanageable.> 48 hours

Transitional care considered if home IV antibiotics are unsafe/unmanageable.

Episode Day 2 and subsequent days — symptomatic infants

a: Signs of neonatal sepsis (examples: hypotonia, lethargy, poor oral feeding, tachycardia, bradycardia, grunting, nasal flaring, cyanosis).
b: Temperature ≥ 100.4 °F or ≤ 96.8 °F (≥ 38.0 °C or ≤ 36.0 °C).≥ 100.4 °F or ≤ 96.8 °F
c: On 48 hours of antibiotics pending blood culture results or receiving treatment for positive blood cultures.48 hours

Asymptomatic infants on antibiotics: Asymptomatic infants on 48 hours of antibiotics pending blood culture results for ≤ two days are appropriate for Level II nursery (rev code 172).≤ 2 days

Asymptomatic with positive blood culture: Asymptomatic infants with a positive blood culture and no other indications are appropriate for transitional care; once culture and sensitivity results are known and the infant is medically stable, transition to a lower level of care for treatment completion if no other indications exist.

Once culture and sensitivity known and infant medically stable, transition to lower level for treatment completion if no other indications.

Discharge criteria (with or without home antibiotics): All applicable: member/enrollee clinically stable; home situation assessed and adequate; parent/caretaker agreeable. If going home with antibiotics, all of the following must be met: contractual agreement with a home infusion company experienced in neonatal IV or short-term IM therapy; secure IV access if chosen; contact information for responsible physician and backup facility provided to family and home care agency prior to discharge; provider follow-up scheduled within 48 hours of discharge.48 hours (follow-up)

There are no explicit exclusions listed in this portion of the policy document.

Coverage and administration of benefits described in this policy are subject to the terms, conditions, exclusions and limitations of the member's coverage documents (for example, evidence of coverage, certificate of coverage, policy or contract of insurance) and to applicable Health Plan administrative policies and procedures; providers should consult those documents when making coverage or prior authorization determinations.

As clinical guidance under these coverage criteria, antibiotic therapy may be discontinued by 36–48 hours of incubation when blood cultures remain sterile unless there is clear evidence of a site-specific infection; this timing reflects the recommended observation period for ruling out early-onset sepsis and informs level-of-care placement and discharge planning.

Billing Rule

Level-of-care coding requirements and placement

Level-of-care placement must match clinical criteria and affects billing/revenue coding. Place well-appearing infants on ≤48 hours of empiric antibiotics pending blood cultures in Level II (revenue code 172). Symptomatic infants meeting sepsis criteria (signs such as hypotonia, lethargy, poor feeding, abnormal temperature, respiratory or cardiovascular instability) and on 48 hours of antibiotics or being treated for positive cultures should be placed in Level III (revenue code 173). Asymptomatic infants on ≤2 days of antibiotics pending cultures are appropriate for Level II (rev code 172); asymptomatic infants with a positive blood culture and no other indications may be appropriate for transitional care. Transitional care or Level I (rev code 171) may be appropriate for infants with negative cultures who require antibiotics beyond 48 hours when antibiotics are the only remaining intervention and outpatient antibiotics are inappropriate or unmanageable.

Level II revenue code: 172 — well-appearing infants on up to 48 hours of antibiotics pending blood culture results
Level III revenue code: 173 — symptomatic infants meeting sepsis criteria and on 48 hours of antibiotics or treating positive cultures
Level I / Transitional revenue code: 171 — infants stable for transitional care or Level I when antibiotics are sole remaining intervention and home therapy is unsuitable

Background and Epidemiology

Group B Streptococcus (GBS) is the leading cause of early-onset neonatal sepsis and remains an important driver of evaluation and empiric therapy in newborns. Identification and intrapartum treatment of colonized or infected birthing individuals reduces early-onset disease, but cases still occur despite negative maternal cultures. Management decisions for neonates therefore balance gestational age, perinatal risk factors, clinical status, and culture results to guide level-of-care placement and duration of therapy.

Definitions and Risk Assessment

inv-17: GBS early-onset disease

DefinitionGroup B Streptococcus (GBS) early-onset disease: blood or cerebrospinal fluid culture-proven infection occurring within the first seven days of life

Clinical relevanceGBS remains the leading cause of early-onset neonatal sepsis; cases can occur despite negative maternal cultures

inv-18: EOS risk assessment

Assessment methodsEOS risk assessment may use categorical risk assessment, the Neonatal Early-Onset Sepsis multivariate calculator, or clinical condition/judgment

Gestational-age noteInfants \u2265 35 weeks should be managed according to risk determined by these methods; preterm infants <= 34 weeks have distinct higher-risk pathways

On This Page

If antibiotics are required beyond 48 hours and home administration is unsafe/unmanageable, consider transitional care or level I nursery (rev code 171)

Prior Authorization

Check Health Plan coverage documents for prior authorization

Verify prior authorization and coverage requirements before delivering non-routine services, home infusion, or extended inpatient stays. Coverage decisions and benefit administration are subject to the member's evidence of coverage, certificate/policy, and applicable state/federal regulations and Health Plan administrative policies.

Check the member's Evidence of Coverage / policy / contract for prior authorization rules and benefit limits
Confirm plan-level prior authorization for home infusion services or extended neonatal admissions when applicable

Note

Empiric antibiotic agents and discontinuation timing

When blood cultures are sterile, empiric antibiotic therapy should be discontinued by 36–48 hours of incubation unless there is clear evidence of site-specific infection. For empiric therapy in term infants at risk for early-onset sepsis, use agents active against Group B Streptococcus and common Gram-negative organisms (e.g., IV ampicillin plus gentamicin). Stable infants ≥35 weeks treated for sepsis should be discharged the same day antibiotics are discontinued when clinically appropriate.

Empiric agents: IV ampicillin + gentamicin (covers GBS and common pathogens like E. coli)
Discontinuation timing: stop antibiotics by 36–48 hours if cultures remain sterile and no evidence of focal infection
Stable ≥35 weeks GA: consider same-day discharge once antibiotics are stopped and clinical stability achieved

Documentation Required

Discharge documentation and home antibiotics requirements

If planning discharge with home antibiotics, document a signed contractual agreement with a home infusion company experienced in neonatal IV therapy or approved short-term intramuscular therapy, confirm secure IV access if chosen, provide contact information for the responsible physician and back-up facility to the family and home care agency prior to discharge, and schedule provider follow-up within 48 hours of discharge.

Home infusion contract signed with experienced neonatal IV therapy provider
Secure IV access documented if home IV therapy planned
Responsible physician and back-up facility contact information provided to family and home care agency before discharge
Follow-up visit scheduled within 48 hours of discharge
