Medical Policy

Effective Date:09/18/1995 Title:Outpatient Hyperbaric Oxygen Therapy (HBOT)
Revision Date:01/01/2017 Document:BI141:00
CPT Code(s):A4575; G0277; 99183
Public Statement

Effective Date:

a)    This policy will apply to all services performed on or after the above Revision date which will become the new effective date.

b)    For all services referred to in this policy that were performed before the revision date, contact customer service for the rules that would apply.

1)    Hyperbaric oxygen therapy (HBOT) is a systemic treatment in which the entire patient is placed inside a pressurized chamber and breathes 100% oxygen under a pressure greater than one atmosphere.  It is used to treat certain diseases and conditions that may improve when increased oxygen is present such as non-healing infected deep ulcerations, acute carbon monoxide poisoning, acute air or gas embolism, or radiation necrosis. 

2)    Emergency hyperbaric oxygen therapy is covered without pre-authorization for the first two units, when performed in the emergency department or as in-patient. Additional units require pre-authorization

3)    Continued treatment with HBOT for wound care is covered when there has been evidence of progressive healing during 30 days of treatment. A renewal of the pre-authorization is required every 30 days or more frequently depending on progress.

4)    For certain conditions, HBOT is considered experimental since HBOT has not been shown to be more effective than conventional treatment.  Examples:

a)    necrotizing arachnidism (severe tissue destruction due to venomous spider bites)

b)    acute or chronic cerebrovascular insufficiency (low blood supply to the brain)

c)     cerebrovascular accident (including thrombotic or embolic stroke)

5)    There are also conditions in which HBOT is dangerous and therefore, not a covered service such as:

a)    Untreated pneumothorax

b)    Concurrent administration of doxorubicin, cisplatin, or disulfiram

c)     Premature infants (birth prior to 37 weeks gestation)

6)    Contact Customer Service for coverage information.

Medical Statement

The first two units for each code 99183 (supervision of hyperbaric oxygen) and G0277 (hyperbaric oxygen 30 minute session), when performed in the emergency room or inpatient hospital setting, do not require pre-authorization. This is to allow emergency hyperbaric oxygen treatment for certain conditions (such as acute carbon monoxide poisoning, decompression illness, acute air/gas embolism or cyanide poisoning).  Anything beyond the first two units requires preauthorization.  If retrospective review finds this is inappropriately being used for chronic conditions the payment may be retrospectively denied/adjusted.  

99183 and G0277 require pre-authorization in all other settings. 

In the outpatient setting, full body hyperbaric oxygen therapy (HBOT) is considered medically necessary for the following conditions:

1.     Non-healing infected deep ulcerations (reaching tendons or bone) of the lower extremity in diabetic adults unresponsive to at least 1 month of meticulous wound care (including aggressive debridement, maximal antibiotic therapy, tight glycemic control, and appropriate treatment of arterial insufficiency, including revascularization if necessary).
HBOT is not considered medically necessary for superficial lesions.

2.     Acute carbon monoxide poisoning.

3.     Decompression illness (“the bends”) – the standard treatment is recompression and decompression without increased oxygen concentration in the air.

4.     Acute air or gas embolism – the standard treatment is recompression and decompression without increased oxygen concentration in the air.

5.     Gas gangrene (Clostridia myositis and myonecrosis).

6.     Cyanide poisoning (with co-existing carbon monoxide poisoning).

7.     Acute traumatic peripheral ischemia (including crush injuries and suturing of severed limbs) when loss of function, limb, or life is threatened and HBOT is used in combination with standard therapy.

8.     Acute peripheral arterial insufficiency (e.g., compartment syndrome).

9.     Progressive necrotizing soft tissue infections, including mixed aerobic and anaerobic infections (necrotizing fasciitis, Meleney`s ulcer).

10. Chronic refractory osteomyelitis, unresponsive to conventional medical        and surgical management.

11. Compromised skin grafts and flaps.

12. Radiation necrosis (osteoradionecrosis, myoradionecrosis, and other soft tissue radiation necrosis) as an adjunct to conventional treatment.

13. Soft tissue radio necrosis as an adjunct to conventional wound care.

14. Exceptional blood loss anemia only when there is overwhelming blood loss and transfusion is impossible because there is no suitable blood available, or religion does not permit transfusions.

15. Pneumatosis cystoids intestinalis.

16. Prophylactic pre- and post-treatment for members undergoing dental surgery of a radiated jaw.

17. Acute cerebral edema.

18. Idiopathic sudden deafness, acoustic trauma or noise-induced hearing loss, when HBOT is initiated within 3 months after onset.

 

Billing: 

-        99183 is for professional services only, and is limited to one unit (session) per day.

-        G0277 is billed by the facility, in 30 minute increments, up to four hours per day.

Codes Used In This BI:

99183    Physician attendance/supv of hyperbaric oxygen therapy, per session

A4575    Hyperbaric O2 chamber disps

G0277   HBOT, full body chamber, per 30 minute interval

Limits
