SOC 2 vs HITRUST for Medical Billing Companies

The two frameworks at a glance

SOC 2 Type II in detail

SOC 2 is a Service Organization Control report defined by the American Institute of Certified Public Accountants (AICPA). Type II evaluates the operating effectiveness of controls over a 6-to-12-month observation period, in contrast to Type I which is a point-in-time evaluation.

Trust criteria (choose which to include):

• Security (always required): protection against unauthorized access
• Availability: system uptime and accessibility
• Processing integrity: complete, valid, accurate, timely processing
• Confidentiality: protection of information designated as confidential
• Privacy: personal information collection, use, retention, disclosure aligned with privacy policy

Most SOC 2 reports include security only or security plus one or two additional criteria. Broader scope adds cost.

Process:

1. Readiness assessment: identify gaps against chosen trust criteria (1-3 months)
2. Remediation: implement missing controls (2-6 months)
3. Observation period: operate controls for 6-12 months while auditor collects evidence
4. Auditor report: independent assessment of control design and operating effectiveness

Deliverable:

The SOC 2 Type II report is a lengthy document (typically 40-100 pages) covering scope, control descriptions, tests performed, and results. A public-facing SOC 3 summary is available for vendors that want to share evidence more broadly.

HITRUST CSF in detail

HITRUST (Health Information Trust Alliance) publishes the HITRUST CSF (Common Security Framework), a healthcare-specific security control framework. Certification demonstrates that an organization has implemented and validated the controls to a specified assurance level.

Assessment levels:

• e1 (Entry-level): 44 controls, foundational cybersecurity, 1-year certification
• i1 (Implemented, 1-year): 182 controls, threat-adaptive baseline, 1-year certification
• r2 (Risk-based, 2-year): 198 to 2,000+ controls scaled by scope and risk, 2-year certification with interim review

Framework coverage:

HITRUST CSF maps to and includes controls from HIPAA, HITECH, NIST 800-53, NIST 800-171, ISO/IEC 27001, PCI DSS, GDPR, CCPA, and dozens of other frameworks. A single HITRUST certification can therefore substantiate compliance-adjacent claims across multiple regulatory regimes.

Process:

1. Scoping: define assessment boundary, systems, and data flows
2. Gap analysis: identify controls not yet implemented (1-3 months)
3. Remediation: implement missing controls (3-9 months)
4. Validated assessment: HITRUST-authorized external assessor evaluates implementation
5. HITRUST review: HITRUST Alliance quality assurance and certification decision
6. Certification: valid for 2 years with interim assessment at 12 months

Deliverable:

A HITRUST certification letter naming the assessed entity, scope, control level, and validity dates. The full assessment report is a substantial document (often several hundred pages) with control-by-control evidence.

When each matters most

SOC 2 makes sense when:

• Serving enterprise customers across multiple industries
• Vendor is smaller and cannot yet absorb HITRUST cost
• Multi-tenant SaaS platform with mixed customer base
• Broad security signal is sufficient for procurement

HITRUST makes sense when:

• Serving large health systems, integrated delivery networks, or major payers
• Handling PHI at significant scale
• Vendor procurement processes at target customers specify HITRUST
• Regulatory scrutiny expected (HHS OCR audits, state AG investigations)

Many billing vendors serving both mid-market physician practices and enterprise health systems carry both certifications simultaneously.

What neither framework guarantees

• Neither certification guarantees no breach. SOC 2 and HITRUST validate control implementation, not future security outcomes. Certified vendors still suffer breaches.
• Neither certification is a HIPAA compliance certificate. HHS OCR issues no HIPAA compliance certification. HITRUST maps more directly to HIPAA but is not a substitute for a HIPAA compliance program.
• Neither certification eliminates the need for a BAA. The BAA remains required regardless of certification status.
• Neither certification covers operational quality. A HITRUST-certified vendor with bad account management delivers bad account management.

Requesting and reviewing certifications

When evaluating a vendor:

Request:

• SOC 2 Type II report (or SOC 3 summary if the full report is confidential)
• HITRUST certification letter and scope statement
• Certification dates (validity window)
• Whether certification covers the specific services your practice uses

Review:

• Certification date within 12 months (SOC 2) or 24 months with interim review (HITRUST)
• Scope covers relevant systems (not just corporate email or unrelated services)
• Trust criteria include security at minimum (SOC 2)
• Any qualifications, exceptions, or noted deficiencies
• Auditor or assessor identity (reputable firm)

Cost-benefit for smaller billing vendors

Small to mid-market medical billing vendors face a real cost question:

• SOC 2: $30K-$100K annual is achievable for most established vendors
• HITRUST r2: $60K-$200K+ every 2 years is a significant investment; many smaller vendors defer
• HITRUST e1 or i1: lower-cost entry points let vendors demonstrate baseline security without full r2 cost

For practices evaluating vendors: presence of SOC 2 signals mature security. Absence of both SOC 2 and HITRUST does not automatically disqualify a vendor, but the vendor should be able to demonstrate equivalent security control implementation through its HIPAA risk analysis, security policies, and incident response procedure.

Bottom line

SOC 2 Type II and HITRUST CSF certifications validate different aspects of a medical billing vendor's security posture. SOC 2 is broader and cheaper; HITRUST is healthcare-specific and more rigorous. Both are optional but increasingly requested in vendor procurement. Neither replaces HIPAA compliance obligations or the required BAA. Use certifications to filter for mature security posture during vendor selection; verify continued operational quality through client references and ongoing performance metrics.
