Documentation Requirements
• Medical record documentation maintained by the performing physician must clearly indicate the medical necessity of the service being billed.
o In addition, documentation that the service was performed must be included in the patient’s medical record.
o This information is normally found in the office/progress notes, hospital notes, and/or procedure report.
• Documentation should support the criteria for coverage as set forth in the “Indications and Limitations of Coverage and/or Medical Necessity” section of this policy.
Utilization Guidelines
• Strapping (Procedure codes 29540 and 29550)
o It is not generally expected that strapping of the ankle, foot and/or toe(s) would be done more often than weekly.
o However, there are circumstances that warrant application of straps several times per week, such as, whirlpool treatments which require removal and reapplication of the straps.
• Hydrotherapy (whirlpool) treatment for decubitus ulcers is a covered service under Medicare for patients when treatment is reasonable and necessary.
o Some other methods of treating decubitus ulcers, the safety and effectiveness of which have not been established, are not covered under the Medicare program.
o Some examples of these types of treatments are: ultraviolet light, low intensity direct current, topical application of oxygen, and topical dressings with Balsam of Peru in castor oil.
• Unna boot (Procedure code 29580).
o It is not expected that Unna boot application would be done more often than once or twice per seven days.
Treatment Logic
• Strapping of the ankle, foot and/or toe(s) consists of the application of nonmedicated, adhesive gauze dressings, applied by overlapping wraps of gauze to exert pressure and hold a structure in place for the purpose of providing structural support, immobilization or compression for the ankle, foot and/or toe(s).
• Unna boot is a paste bandage which consists of gauze that has been impregnated with zinc oxide, gelatin, glycerin, and sometimes calamine.
o The bandage is applied to the leg from the toe to the knee by overlapping wraps of impregnated gauze.
o The Unna boot forms a semirigid soft cast which should be left in place for 4 to 7 days.
o The Unna boot bandage restricts the volume of the leg, controls edema, and encourages more normal prograde venous blood flow with reduction in the subcutaneous blood pressure.
o The net effect is improved healing of venous stasis ulcers of the lower extremities.
