ACHC Home Infusion Therapy Accreditation: Medicare Part B Enrollment for a Growing Infusion Provider
Client Case Study — Anonymized
Client Profile
- Organization Type: Independent home infusion pharmacy and clinical services provider
- Size: Growing organization — approximately 200 active patients across anti-infective, TPN, and biologic therapy programs
- Services: Anti-infective therapy, TPN, specialty biologics, hydration therapy; nursing services for patient assessment and training
- Prior Accreditation: URAC Specialty Pharmacy Accreditation (for commercial payer networks); no CMS-approved home infusion therapy accreditation
- Driver for Engagement: Medicare Part B home infusion therapy benefit enrollment under the 21st Century Cures Act — required CMS-approved accreditation that URAC does not provide
Situation
The organization had been providing home infusion services to commercial payer patients for four years and held URAC Specialty Pharmacy Accreditation. When the Medicare home infusion therapy benefit became effective in 2021, the organization initially operated without Medicare enrollment, referencing commercial payer revenue as sufficient. By 2025, the volume of Medicare-eligible patients being referred to the organization — and turned away or billed privately — had grown to a level that made Medicare enrollment strategically essential.
The organization engaged IHS to prepare for ACHC Home Infusion Therapy Accreditation, leveraging their existing URAC accreditation as a foundation but addressing the significant standards differences between URAC and ACHC in the clinical services domain.
IHS's initial assessment identified three significant gaps between the URAC-accredited program and ACHC requirements:
- Patient and caregiver training documentation: URAC standards require patient education; ACHC requires documented competency demonstration. The organization's training records documented education delivery but not assessed competency — a critical distinction.
- Infection surveillance: The organization tracked adverse events but did not have a formal CRBSI surveillance system with prospective monitoring, rate calculation, and trend reporting.
- 24/7 clinical support documentation: On-call nursing and pharmacy coverage existed but was not documented — no on-call logs, call records, or response documentation was maintained.
IHS Approach
Phase 1: URAC-to-ACHC Gap Analysis (Month 1)
IHS conducted a targeted analysis comparing the organization's existing URAC-compliant policies and systems to ACHC Home Infusion Therapy requirements. This approach avoided redundant work on the substantial overlap between the two programs while identifying the specific ACHC-unique requirements that needed to be addressed.
Phase 2: Patient Training Competency System (Months 1-3)
IHS designed therapy-specific competency assessment tools for all four therapy categories — anti-infective, TPN, biologics, and hydration. Each tool included: a structured skills checklist, a return demonstration assessment, a knowledge verification component, and a documentation of the patient's or caregiver's demonstrated ability to manage infusion therapy independently between nursing visits. Nursing staff were trained on the new competency assessment approach and the documentation standard.
The organization also implemented a "competency re-assessment trigger" system — automatically flagging patients for competency re-evaluation when therapy changes, after hospitalizations, or at 90-day intervals for complex therapies.
Phase 3: CRBSI Surveillance System (Months 2-4)
IHS designed a formal CRBSI surveillance system using CDC NHSN definitions for central line-associated bloodstream infections (CLABSIs). The system included: prospective patient tracking by catheter type and therapy category, monthly rate calculation (infections per 1,000 catheter days), root cause analysis for each identified infection, and quarterly trend reporting to the QAPI committee. Six months of surveillance data was available by survey time.
Phase 4: 24/7 Documentation System (Month 2)
IHS implemented an on-call documentation system capturing: all after-hours patient or caregiver calls, the clinical concern reported, the clinician response, and any follow-up action taken. The system was simple — a structured call log maintained by the on-call nurse and reviewed weekly by the clinical director — but generated the documentation trail that ACHC surveys require.
Phase 5: Policy Integration and Mock Survey (Months 5-8)
IHS integrated ACHC-specific requirements into the organization's existing URAC-aligned policy library, avoiding policy duplication while ensuring ACHC standards were explicitly addressed. The mock survey in month 8 identified two findings: one patient record where the competency re-assessment trigger had not been activated after a hospitalization, and one month where the CRBSI rate calculation had used an incorrect denominator. Both were corrected within one week.
Outcome
- Survey Result: ACHC accreditation awarded with zero RFI findings
- Timeline: 9 months from engagement to accreditation award
- Medicare Enrollment: Medicare Supplier Number obtained following accreditation; organization began billing for Medicare home infusion therapy benefit within 60 days of accreditation award
- CRBSI Surveillance: 6 months of surveillance data demonstrated rates below national benchmarks; data used in commercial payer quality reporting
- URAC Alignment: All new ACHC systems designed to satisfy both programs — no duplication of documentation effort required for the next URAC renewal cycle
Key Lessons for Home Infusion Providers
- URAC and ACHC have significant overlap but critical differences. Organizations with URAC accreditation should not assume ACHC readiness — the patient training competency documentation standard is a material difference that requires system redesign, not just policy adjustment.
- 24/7 coverage must be documented, not just real. Many providers have genuine 24/7 coverage that they cannot demonstrate because they have never maintained call logs. This is a fixable problem that takes 30 days to address — but only if you start before the survey.
- CRBSI surveillance is not adverse event reporting. The two are different things. Adverse event reporting captures incidents after they occur; CRBSI surveillance proactively monitors all patients with central access to detect infection signals early. ACHC requires the latter.
