    Clinical & Coding Specifications

    Clinical Context

    A typical patient is an adult with a chronic, non-healing wound such as a diabetic foot ulcer, refractory osteoradionecrosis, or refractory soft tissue radionecrosis referred to a hyperbaric oxygen (HBO) facility. The patient arrives to an outpatient hyperbaric suite or hospital-based hyperbaric medicine unit for a planned course of C1300 therapy. Intake includes verification of indications, consent, and pre-treatment evaluation by a hyperbaric medicine physician or qualified clinician. Vital signs and a focused history (including recent chemotherapy, pneumothorax history, claustrophobia, and pulmonary status) are reviewed. The patient is assisted into a full-body monoplace chamber or a multiplace chamber depending on facility capability and staffing.

    During treatment, the chamber is pressurized to the prescribed atmospheric pressure (commonly 2.0–2.5 ATA) while the patient breathes 100% oxygen for the therapeutic period. Monitoring during each C1300 30-minute interval includes observation for barotrauma, oxygen toxicity symptoms, and claustrophobic distress. Nursing or hyperbaric technologist documents start and stop times, any interruptions, and patient tolerance. Typical course ranges from 20 to 40 treatments delivered once daily, five days per week, depending on indication and clinical response. Post-treatment, the clinician documents skin and wound status changes, any adverse events, and schedules subsequent sessions or follow-up care.
