A Strategic and Clinical Framework for Building a Safe, Compliant, and Sustainable Hyperbaric Medicine Service
Starting a hospital-based hyperbaric medicine program is not primarily an equipment-purchasing project. It is the development of a specialized clinical service that combines medical decision-making, pressure-vessel operations, oxygen fire safety, engineering controls, physician supervision, emergency preparedness, and payer-specific documentation.
The strongest programs begin by defining the patients they intend to serve, the clinical capabilities they can support, and the outcomes they expect to improve. Chamber selection, construction, staffing, and financial planning should follow that clinical strategy.
Hyperbaric chambers are FDA-regulated Class II medical devices. The FDA advises facilities to follow each device’s instructions for use, maintain staff training, monitor patients throughout treatment, perform required maintenance and safety checks, and implement strict fire-prevention controls. (U.S. Food and Drug Administration)
Define the Clinical Scope Before Selecting a Chamber
Hospital leadership should first determine whether the program will function primarily as an outpatient wound and radiation-injury service, an emergency hyperbaric referral center, or a broader hospital-based program capable of treating critically ill patients.
A planned clinical scope may include:
- Advanced diabetic lower-extremity wounds
- Delayed radiation tissue injury
- Chronic refractory osteomyelitis
- Compromised grafts and flaps
- Carbon monoxide poisoning
- Arterial gas embolism
- Decompression illness
- Necrotizing soft tissue infections
- Crush injuries and acute traumatic ischemia
These conditions do not create equivalent operational requirements. A program treating stable outpatients during business hours requires a different staffing, chamber, and emergency model from a center accepting intubated patients, emergency transfers, or time-sensitive diving injuries.
The Medicare National Coverage Determination for HBOT identifies specific covered conditions and describes HBOT as adjunctive treatment for several of them. Medicare does not cover every proposed use of hyperbaric oxygen, and coverage requirements may include disease severity, failure of standard care, or continued documentation of improvement. (Centers for Medicare & Medicaid Services)
The hospital should define clearly:
- Which indications will be accepted
- Whether inpatient and outpatient treatment will be available
- Whether emergency referrals will be accepted
- The maximum level of patient acuity
- Whether ventilated or hemodynamically unstable patients can be treated
- Which specialties will share responsibility for patient management
- When patients must be transferred to another hyperbaric center
A program should not advertise emergency or critical-care capability unless staffing, equipment, chamber access, and hospital support can reliably provide that level of service.
Establish Medical and Administrative Governance
A hospital hyperbaric service requires clear clinical ownership. Leadership should identify a qualified hyperbaric medical director early in the planning process rather than waiting until the chamber is installed.
The medical director should help establish:
- Clinical indications and exclusion criteria
- Physician credentialing and privileging requirements
- Treatment protocols
- Emergency procedures
- Patient-screening standards
- Quality metrics
- Peer review and utilization review
- Relationships with referring specialties
The Undersea and Hyperbaric Medical Society publishes current guidance for credentialing, privileging, and supervision of physicians and other clinicians involved in HBOT. UHMS guidance supports formal training, appropriate proctored experience, and privileges that reflect the provider’s education and demonstrated competence. (UHMS)
Administrative governance should include representatives from:
- Hospital medical leadership
- Nursing
- Respiratory therapy
- Facilities and engineering
- Fire and life safety
- Infection prevention
- Risk management
- Pharmacy
- Finance and revenue cycle
- Emergency medicine
- Surgery and critical care
- Wound care
- Compliance and legal services
This group should remain involved through design, construction, commissioning, and clinical launch. Hyperbaric medicine crosses too many operational boundaries to be developed successfully by one department working in isolation.
Complete a Realistic Market and Referral Analysis
A feasibility assessment should be based on identifiable referral volume, not general assumptions about the prevalence of chronic wounds.
The hospital should evaluate:
- Current inpatient and outpatient cases that may meet recognized indications
- Radiation oncology survivorship volume
- Diabetic foot and limb-preservation referrals
- Vascular, podiatric, orthopedic, colorectal, urologic, and head-and-neck surgery volume
- Existing wound-center activity
- Regional trauma and emergency referral patterns
- Competing hyperbaric centers
- Travel distance for patients
- Payer mix and authorization requirements
Claims data alone may overstate demand. A patient with a diabetic foot ulcer, for example, does not automatically qualify for HBOT. Medicare coverage requires a diabetes-related lower-extremity wound classified as Wagner grade III or higher, failure of at least 30 days of standard wound therapy, and continued use of comprehensive wound care. (Centers for Medicare & Medicaid Services)
The volume model should account for the number of treatments per patient, chamber occupancy, cancellation rates, staffing ratios, emergency capacity, preventive maintenance, and the time required for patient preparation and turnover.
A program that requires consistently unrealistic chamber utilization to break even is not financially resilient.
Choose Between Monoplace and Multiplace Capability
Monoplace chambers generally treat one patient at a time. The patient is commonly surrounded by an oxygen-rich chamber atmosphere while clinical personnel remain outside.
Multiplace chambers can accommodate multiple patients and may allow trained personnel to remain inside. The chamber is usually pressurized with air while oxygen is delivered through a mask, hood, or airway circuit.
Neither design is inherently more therapeutic. Chamber selection should reflect the intended patient population and operational model.
Monoplace systems may be appropriate when the program expects:
- Primarily stable outpatients
- Individualized treatment scheduling
- Several simultaneous but independently controlled treatments
- Limited need for direct bedside intervention under pressure
- A lower initial construction footprint than a large multiplace installation
- Multiplace capability may be advantageous when the program expects:
- Critically ill or ventilated patients
- Pediatric patients requiring an attendant
- Patients who need direct clinical assistance
- Multiple patients with compatible treatment profiles
- Emergency diving or gas-embolism referrals
- Complex in-chamber monitoring or intervention
The chamber decision should include an assessment of lifecycle costs, staffing, oxygen and compressed-air infrastructure, maintenance, redundancy, evacuation, emergency access, and future service expansion.
Only FDA-cleared devices should be considered for their cleared intended use. FDA-cleared full-body hyperbaric chambers can be identified under product code CBF, and facilities should review the specific clearance, operating limits, accessories, and manufacturer instructions for each proposed system. (U.S. Food and Drug Administration)
Involve Engineering and Code Authorities Early
Hyperbaric construction should begin with a multidisciplinary design review involving the chamber manufacturer, hospital engineering, architects, mechanical and electrical engineers, fire protection specialists, infection prevention, clinical users, and the authority having jurisdiction.
NFPA 99 contains specific provisions for the design and operation of hyperbaric facilities in Chapter 14. The edition legally adopted by a state or local jurisdiction may differ, so the project team must verify the applicable code with the relevant authority. FDA safety resources also identify NFPA 99 and ASME PVHO-1 as central references for hyperbaric facilities and pressure vessels for human occupancy. (NFPA)
Facility planning may need to address:
- Chamber location and structural loading
- Oxygen and compressed-air supplies
- Ventilation and exhaust
- Electrical classification and grounding
- Fire detection and suppression
- Emergency power
- Patient and equipment egress
- Stretcher and wheelchair access
- Control panels and visibility
- Medical gas alarms
- Environmental monitoring
- Storage of approved supplies
- Separation from ignition sources
- Access for preventive maintenance
The design should also reflect actual patient flow. A critically ill patient should not require transport through congested public areas. An outpatient with limited mobility should have safe access to changing areas, restrooms, glucose testing, wound assessment, and emergency care.
Equipment placement should allow staff to observe patients continuously and respond without unnecessary delay.
Build a Qualified Hyperbaric Team
A hospital hyperbaric program requires more than a physician and a chamber operator. Staffing should reflect the chamber configuration, patient acuity, treatment volume, and services offered.
The core team may include:
- Hyperbaric medical director
- Credentialed hyperbaric physicians
- Registered nurses
- Hyperbaric technologists
- Respiratory therapists
- Wound-care clinicians
- Hyperbaric safety director or coordinator
- Program manager
- Biomedical and facilities support
- Revenue-cycle and authorization staff
Programs treating unstable or ventilated patients may also require support from critical care, anesthesia, emergency medicine, surgery, pharmacy, and respiratory therapy.
UHMS recommends using formal hyperbaric operations and credentialing guidance to determine appropriate staffing and qualifications. Staffing decisions should account for patient acuity, chamber type, team experience, emergency responsibilities, and the ability to respond safely when more than one patient is under pressure. (UHMS)
Training should include:
- Hyperbaric physiology and gas laws
- Patient selection and contraindications
- Ear and sinus pressure management
- Oxygen toxicity recognition
- Chamber operation
- Fire prevention
- Approved and prohibited materials
- Emergency decompression
- Cardiac and respiratory emergencies
- Glucose management
- Equipment compatibility
- Infection prevention
- Patient transfer and evacuation
Staff competency should be verified through direct observation, simulation, written assessment, and documented retraining. Attendance at an educational course does not, by itself, establish operational competence.
Appoint a Hyperbaric Safety Director
The hyperbaric safety director or coordinator should be appointed during planning, not after the program opens.
This role typically oversees:
- Fire-safety policies
- Product and equipment risk assessment
- Chamber-compatible materials
- Preventive maintenance coordination
- Safety training
- Emergency drills
- Incident and near-miss review
- Regulatory and code compliance
- Changes to equipment or clinical practice
- Contractor and vendor access
UHMS accreditation guidance evaluates the qualifications and responsibilities of the hyperbaric safety function. UHMS also recommends specialized safety education and sufficient operational experience for those responsible for this role. (UHMS)
The safety director should have meaningful authority. A program is not safe when the designated safety professional can identify a hazard but lacks the authority to stop a treatment, reject an item, or remove equipment from service.
Create a Comprehensive Fire-Safety System
Oxygen does not ignite independently, but it allows combustible materials to ignite more easily and burn with greater intensity. Fire prevention must therefore be embedded into every stage of treatment.
The FDA’s August 25, 2025 safety communication emphasizes:
- Following manufacturer instructions
- Using proper grounding
- Maintaining staff training
- Monitoring and supervising patients
- Following cleaning and maintenance schedules
- Controlling electrical and static-producing items
- Using hyperbaric-compatible clothing
- Maintaining fire-prevention procedures (U.S. Food and Drug Administration)
The program should develop a formal approval process for every item entering the chamber environment, including:
- Patient clothing and linens
- Wound dressings
- Skin products
- Catheters and tubing
- Monitoring devices
- Prostheses and implants
- Infusion equipment
- Batteries and electronics
- Cleaning products
- Emergency supplies
An item used routinely elsewhere in the hospital is not automatically safe under pressure or in an oxygen-enriched environment.
The hospital should also conduct drills for chamber fire, external fire, power failure, gas-supply failure, communication loss, patient seizure, cardiac arrest, respiratory deterioration, and emergency evacuation.
Develop Standardized Clinical Pathways
Each accepted diagnosis should have a written clinical pathway that defines:
- Referral requirements
- Diagnostic criteria
- Required records
- Standard-care prerequisites
- Contraindication screening
- Treatment protocol
- Monitoring requirements
- Reassessment intervals
- Discontinuation criteria
- Coordination with the referring specialist
A diabetic wound pathway, for example, should confirm vascular assessment, offloading, debridement, infection treatment, glucose management, nutritional support, wound measurement, and failure of standard care when required. CMS specifically states that HBOT must supplement, not replace, these measures. (Centers for Medicare & Medicaid Services)
A radiation-injury pathway should include confirmation of prior radiation exposure, evaluation for recurrent malignancy, organ-specific specialist assessment, and documentation of conventional treatment.
Emergency pathways should define how surgery, resuscitation, antibiotics, critical care, and HBOT will be sequenced. Chamber treatment must not delay a time-critical operation or another definitive intervention.
Build Reimbursement and Documentation Processes Before Launch
Revenue-cycle planning should occur before the first patient is scheduled.
The hospital should create payer-specific matrices for:
- Covered diagnoses
- Prior authorization
- Required wound classifications
- Standard-care documentation
- Physician supervision
- Treatment units
- Continued-coverage requirements
- Medical-necessity appeals
- Inpatient versus outpatient billing
CMS treats HBOT as a physician and hospital outpatient service and limits national Medicare coverage to listed indications. HBOT for diabetic lower-extremity wounds requires continued wound evaluation, and treatment is not covered when measurable healing is not demonstrated during a 30-day treatment period. (Centers for Medicare & Medicaid Services)
Documentation should establish:
- The qualifying diagnosis
- Why HBOT is medically necessary
- Treatments already attempted
- Relevant imaging, cultures, operative findings, or radiation records
- The prescribed pressure and oxygen exposure
- Patient assessment before and after each session
- Adverse events or treatment modifications
- Objective response to therapy
- Continued coordination with standard care
The program should audit documentation before launch using test cases. Discovering a documentation gap after claims are denied is expensive and may expose the hospital to compliance risk.
Commission the Facility Before Treating Patients
Installation does not mean the program is ready for clinical use.
Commissioning should verify:
- Chamber installation and manufacturer acceptance
- Medical gas function
- Pressure controls and alarms
- Communications
- Grounding
- Fire protection
- Emergency power
- Environmental systems
- Preventive maintenance schedules
- Equipment compatibility
- Staff competency
- Emergency response
- Documentation systems
- Medication and supply workflows
The team should perform simulated treatments using realistic scenarios. These exercises should include stable outpatients, nonambulatory patients, glucose abnormalities, ear pain, anxiety, oxygen-delivery failure, seizure, cardiac symptoms, and emergency decompression.
Problems identified during simulation should be corrected before patient treatment begins.
Pursue Hyperbaric Facility Accreditation
UHMS accreditation evaluates the adequacy of a facility’s equipment, staffing, training, policies, safety systems, and quality of patient care. Accreditation is voluntary in many settings, but it provides an external review specifically designed for clinical hyperbaric operations. (UHMS)
Accreditation readiness should be incorporated from the beginning. Designing policies, staffing, records, and physical space around recognized standards is more efficient than attempting to rebuild the program after it is operational.
The hospital should conduct a formal gap analysis before opening and repeat it before an accreditation survey.
Measure Clinical Quality and Operational Performance
A hyperbaric program should be evaluated by more than chamber occupancy and revenue.
Useful quality measures may include:
- Treatment completion rates
- Ear and sinus barotrauma
- Oxygen-toxicity events
- Glucose-related interruptions
- Emergency decompressions
- Fire-safety variances
- Prohibited-item interceptions
- Equipment failures
- Wound-healing progress
- Limb preservation
- Resolution of radiation-related bleeding
- Graft or flap salvage
- Hospitalizations and emergency visits
- Patient-reported function
- Documentation and authorization denials
Near misses should be reviewed even when no injury occurs. A prohibited item found before compression, an incorrect treatment profile caught during the safety pause, or an equipment alarm detected during setup can reveal weaknesses in the system.
The quality process should include regular case review, treatment-utilization review, policy updates, staff education, and documented corrective actions.
Common Mistakes When Starting a Hospital Hyperbaric Program
Several planning errors can weaken an otherwise promising service:
- Purchasing chambers before defining the clinical model
- Building the business plan around noncovered or poorly supported indications
- Treating the program as an extension of wound care rather than a separate specialty service
- Underestimating fire-safety and engineering requirements
- Delaying recruitment of the medical director and safety director
- Assuming existing hospital equipment is chamber compatible
- Advertising emergency capability without sustainable staffing
- Failing to integrate vascular, surgical, infectious disease, radiation oncology, and critical-care services
- Opening before emergency drills and competency validation are complete
- Measuring success primarily through treatment volume
A successful hospital hyperbaric program is a clinical system supported by specialized equipment, not an equipment service searching for patients.
The hospital should be able to explain why the program is needed, which patients it will treat, how those patients will be protected, how outcomes will be measured, and how the service will integrate with the rest of the organization. When those questions are answered before construction begins, the program is far more likely to provide safe, clinically appropriate, and sustainable care.
