Where the denial was overturned

He was reported to be riding unhelmeted when his front tire blew out and he was thrown from his bicycle. There was reportedly a witnessed loss of consciousness. Medics on the scene noted concern for a “soft spot” on the patient’s occipital region. There was a 3-inch laceration noted to the left parietal scalp and multiple abrasions including left hip, knee, elbow and arm. The patient was initially attended to by a ground ambulance crew, however air ambulance services were requested to transport the patient to the hospital. The patient’s vital signs in the field were stable and the patient had a Glasgow Coma Scale (GCS) score of 15 at the time of transport.

A 35-year-old female has requested coverage for past air ambulance transport services. Findings: The physician reviewer found that the patient is a gravida 4, para 0, Ab 3 female who was 32 and 2/7-weeks pregnant when her membranes ruptured and she began having episodic uterine contractions. She presented to the Emergency Department (ED) and was admitted for observation and fetal monitoring. The fetus’ heart rate did not become abnormal. She was consulted on and physical examination revealed that the patient was 80% effaced and 1-cm dilated. Laboratory tests confirmed that the vaginal fluid leak was amniotic fluid. She was also noted to have a culture-proven group B strep urinary tract infection (UTI). She was treated with penicillin for her UTI, Decadron to prevent lung disease associated with pre-term delivery, and terbutaline to inhibit additional contractions.
