Coverage Criteria:

A group II support surface may be covered if the patient meets the following medical criteria:

  • Multiple stage II pressure ulcers located on the trunk or pelvis and patient has been on a comprehensive ulcer treatment program for at least the past month which has included the use of a group I support surface, and the ulcers have worsened or remained the same over the past month OR

When a group II support surface is covered following a myocutaneous flap or skin graft, coverage generally is limited to 60 days from the date of surgery.
  • If the patient is on a group II surface, there should be a care plan established by the physician or home care nurse which generally should include:
    • Education of the patient and caregiver on the prevention and/or management of pressure ulcers,
    • Regular assessment by a nurse, physician, or other licensed healthcare practitioner,
    • Appropriate turning and positioning,
    • Appropriate wound care,
    • Appropriate management of moisture/incontinence,
    • Nutritional assessment and intervention consistent with the overall plan of care.
  • Continued use of a group 2 support surface is covered until the ulcer is healed or, if healing does not continue, there is documentation in the medical record to show that: (1) other aspects of the care plan are being modified to promote healing, or (2) the use of the group 2 support surface is medically necessary for wound management.
