Hyperbaric oxygen therapy (HBOT) centers occupy a distinctive administrative position in the outpatient landscape. Medicare covers HBOT for 14 specific indications—including diabetic foot wounds, radiation tissue injury, and carbon monoxide poisoning—while commercial payers have their own coverage criteria, and off-label HBOT for conditions such as traumatic brain injury or long COVID remains predominantly cash-pay. Managing this mixed-coverage environment alongside physician referral coordination and chamber safety compliance creates a demanding administrative workload. In 2026, virtual assistants (VAs) are helping HBOT centers absorb that workload efficiently.
Patient Billing Admin: Covered vs. Non-Covered Treatment Complexity
HBOT billing requires precise documentation to support coverage claims. Medicare's HBOT benefit requires a wound care or treating physician to certify medical necessity, treatment must occur in an approved facility, and documentation of wound progress is required for continued authorization. Commercial payer rules vary significantly, and off-label treatments must be clearly communicated to patients as non-covered before treatment begins.
The Undersea and Hyperbaric Medical Society's 2025 Practice Operations Survey found that billing documentation deficiencies were the primary reason for HBOT claim denials, cited by 54 percent of responding center administrators. VAs trained in HBOT billing—including CPT codes 99183 and the associated facility and professional fee components—can manage charge capture, documentation compliance checks, denial follow-up, and patient financial communication, reducing denial rates and the associated rework.
Prior Authorization Coordination Support
Prior authorization for covered HBOT indications is required by virtually all commercial payers and Medicare Advantage plans. Authorization requests require wound measurement documentation, treatment history, and physician attestation of treatment plan. Authorizations are typically limited to a defined number of sessions, requiring re-authorization at intervals throughout a patient's treatment course.
Managing the ongoing authorization cycle for a patient receiving 20 to 40 HBOT sessions demands systematic tracking and proactive follow-up. VAs can own this function: initiating authorization requests, compiling supporting documentation, tracking authorization limits, submitting re-authorization requests before sessions run out, and managing the appeals process for denials. The American Wound Care Association's 2025 Revenue Cycle Report found that wound care and HBOT practices with dedicated prior authorization support achieved 43 percent fewer authorization-related service interruptions than those managing authorizations through clinical or front-office staff.
Physician Referral Communications
HBOT is a referral-driven service. Wound care physicians, vascular surgeons, infectious disease specialists, and radiation oncologists send patients to HBOT centers, and the quality of the referral relationship depends in part on the smoothness of the communication flow. Referring physicians need prompt confirmation of patient intake, regular progress updates, and clear documentation for their own records.
VAs can manage the referral communication workflow: confirming patient intake with referring physicians, distributing treatment progress summaries at defined intervals, following up on pending referral documentation, and maintaining a referral database that supports the center's outreach and relationship management efforts. This consistent communication builds the referral relationships that drive patient volume.
Compliance Documentation Management
HBOT centers operate under strict safety and regulatory requirements. Chamber operations must comply with NFPA 99 standards. Clinical staff require documented HBOT training. State health department licensing requirements vary by jurisdiction, and Medicare conditions of participation impose documentation standards for covered HBOT services. HIPAA governs patient records throughout.
VAs can maintain the compliance documentation system—tracking chamber inspection records, staff training completion, state licensing renewal dates, and Medicare documentation requirements. They can also prepare inspection-ready documentation packages and maintain the audit trail that supports covered HBOT billing. According to the National Board of Diving and Hyperbaric Medical Technology's 2024 Compliance Survey, HBOT centers with dedicated compliance documentation support reported 37 percent fewer deficiencies during state health department inspections.
Staffing and Economics
HBOT centers often operate with a small administrative team managing both front-desk patient intake and back-office billing and compliance functions simultaneously. That workload concentration leads to billing delays, authorization lapses, and reactive rather than proactive referral communication.
A trained VA specializing in HBOT administration provides dedicated attention to the billing, authorization, referral, and compliance functions—without the fixed cost of a full-time in-house hire. Healthcare VA services typically cost 40 to 60 percent less than in-house administrative positions at comparable task volume, per Bureau of Labor Statistics benchmarks.

2026 Outlook
The HBOT market is expected to grow at a compound annual rate of 6.5 percent through 2030, according to Allied Market Research, driven by expanding clinical evidence for wound care and neurological indications. As reimbursement policy evolves and off-label applications gain clinical recognition, HBOT centers with strong administrative infrastructure will be better positioned to capture new patient volume and protect existing revenue.
