CMS National Coverage PolicyN/AArticle TextNON-MEDICAL NECESSITY COVERAGE AND PAYMENT RULESFor any item to be covered by Medicare, it must 1) be eligible for a defined Medicare benefit category, 2) be reasonable and necessary for the diagnosis or treatment of illness or injury or to improve the functioning of a malformed body member, and 3) meet all other applicable Medicare statutory and regulatory requirements. Information provided in this policy article relates to determinations other than those based on Social Security Act Section 1862(a)(1)(A) provisions (i.e. "reasonable and necessary").Ostomy supplies are covered under the Prosthetic Device benefit (Social Security Act Section 1861(s)(8)). In order for a beneficiarys equipment to be eligible for reimbursement the reasonable and necessary (R&N) requirements set out in the related Local Coverage Determination must be met. In addition, there are specific statutory payment policy requirements, discussed below, that also must be met.Ostomy supplies are covered for use on a beneficiary with a surgically created opening (stoma) to divert urine, or fecal contents outside the body. Ostomy supplies are appropriately used for colostomies, ileostomies or urinary ostomies (see covered diagnosis codes below.) Use for other conditions will be denied as noncovered.A pouch cover should be coded A9270 and will be denied as a noncovered item.Ostomy supplies are not separately payable when a beneficiary is in a covered home health episode. Ostomy supplies must be provided by the home health agency and payment is included in the home health Medicare payment rate. It is not appropriate to bill these to the DME MAC.REQUIREMENTS FOR SPECIFIC DMEPOS ITEMS PURSUANT TO Final Rule 1713 (84 Fed. Reg Vol 217)Final Rule 1713 (84 Fed. Reg Vol 217) requires a face-to-face encounter and a Written Order Prior to Delivery (WOPD) for specified HCPCS codes. CMS and the DME MACs provide a list of the specified codes, which is periodically updated. The required Face-to-Face Encounter and Written Order Prior to Delivery List is availablehere.Claims for the specified items subject to Final Rule 1713 (84 Fed. Reg Vol 217) that do not meet the face-to-face encounter and WOPD requirements specified in the LCD-related Standard Documentation Requirements Article (A55426) will be denied as not reasonable and necessary.If a supplier delivers an item prior to receipt of a WOPD, it will be denied as not reasonable and necessary. If the WOPD is not obtained prior to delivery, payment will not be made for that item even if a WOPD is subsequently obtained by the supplier. If a similar item is subsequently provided by an unrelated supplier who has obtained a WOPD, it will be eligible for coverage.POLICY SPECIFIC DOCUMENTATION REQUIREMENTSIn addition to policy specific documentation requirements, there are general documentation requirements that are applicable to all DMEPOS policies. These general requirements are located in the DOCUMENTATION REQUIREMENTS section of the LCD.Refer to the LCD-related Standard Documentation Requirements article, located at the bottom of this Policy Article under the Related Local Coverage Documents section for additional information regarding GENERAL DOCUMENTATION REQUIREMENTS and the POLICY SPECIFIC DOCUMENTATION REQUIREMENTS discussed below.For quantities of supplies that exceed the usual maximum amount, there must be information in the medical record that explains the need for the increased amount. This information must be available upon request.Claims for tape and adhesive (A4450, A4452, A5120) that are billed without an AU modifier or another modifier indicating coverage under a different policy will be rejected as missing information.CONTINUED MEDICAL NEEDFor all DMEPOS items, the initial justification for medical need is established at the time the item(s) is first ordered, therefore, beneficiary medical records demonstrating that the item is reasonable and necessary are created just prior to, or at the time of, the creation of the initial prescription. Once initial medical need is established, ongoing need for ostomy supplies is assumed to be met. There is no requirement for further documentation of continued medical need as long as the beneficiary continues to meet the Prosthetic Devices benefit.CODING GUIDELINESBARRIERS:A solid barrier (wafer) is an interface between the beneficiary's skin and the pouching system, has measurable thickness and has an adhesive property. Barriers may be integrated into a "1 piece" pouch, they may be manufactured with a flange and be part of a "2 piece" pouch system (skin barrier with flange, e.g., A4414), or they may be used independently (e.g., A4362), usually with a pouch that does not have its own integral skin barrier. An extended wear barrier (e.g., A4409) is a pectin-based barrier with special additives which achieve a stronger adhesive seal, resist breakdown by urine or bowel effluent, permit longer wear times between changes, and normal wear times for those who cannot achieve them with standard barriers. There are distinct codes for extended wear compared to standard wear barriers.A barrier with built-in convexity (e.g., A4407 or A4411) is one in which an outward curve is usually achieved with plastic embedded in the barrier, allowing better protrusion of the stoma and adherence to the skin. There are distinct codes for barriers with built-in convexity compared to flat barriers.Ostomy skin barriers greater than 4x4 inches (e.g., A4408) refer to the size of the skin barriers themselves, and not to the area of any surrounding tape.FACEPLATES:A faceplate is a solid interface between the beneficiarys skin and the pouch. It is usually made of plastic, rubber or encased metal. It does not have an adhesive property and there is no pectin-based or karaya material that is an integral part of a faceplate. It can be taken off the skin and reattached repeatedly. It is secured by means of a separate adhesive and/or an elastic belt. The clips for attaching the belt are usually a part of the faceplate. There is no coding distinction between flat and convex faceplates.The following table lists codes for faceplate systems. When supplying a pouch with faceplate attached (Column I) a claim may not be made for a component product from Column II provided at the same time.Column IColumn IIA4375A4361, A4377A4376A4361, A4378A4379A4361, A4381, A4382A4380A4361, A4383A4416A4366A4417A4366A4418A4366A4419A4366A4423A4366A4424A4366A4425A4366A4427A4366POUCHES:A pouch is a device for collecting stomal output. A pouch for collecting bowel effluent may be either "drainable" with an opening at the bottom through which the fecal contents are emptied, or closed with a sealed bottom and no outlet. A "urinary" pouch normally incorporates anti-reflux devices and a tap or spigot to empty the urine contents.A pouch "with barrier attached" is one type of "1 piece" system in which a solid barrier is part of the pouch. There are distinct codes for 1-piece pouches with convex barriers and extended wear barriers (see "Barriers").A pouch "without barrier attached" is a pouch with or without a thin adhesive coating that is applied either directly to the skin or to a separate barrier. It is also described as a "1 piece" system.A pouch, which is part of a 2 piece system, has a flange, which enables it to be coupled to a skin barrier with flange.A pouch "with faceplate attached" or "for use on a faceplate" is generally rubber or heavy plastic. It is drainable, cleanable, and reusable for periods of weeks to months, depending on the product.A "high output" pouch (A4412, A4413, A4435) has a capacity of greater than or equal to 0.75 liters, is drainable with a large bore solid spout with cap or plug, and is either part of a 2 piece system (A4412, A4413) or a single-piece system (A4435).Codes for pouches with filters (e.g., A4416) describe pouches that have an opening which allows venting of trapped gas. They typically include materials such as charcoal to deodorize the vented gas. Code A4368 describes replacement filter material.Code A4366 describes a separate ostomy vent that can be added by the beneficiary to a pouch to allow the release of gas. This code must not be used for pouches in which a vent with a filter is incorporated in the pouch by the manufacturer. Those products are described by the codes for ostomy pouches with a filter (A4416, A4417, A4418, A4419, A4423, A4424, A4425, A4427).Absorbent material (A4422) that is added to the ostomy pouch may come as sheets, pads or crystals.An ostomy pouch with faucet-type tap with valve (e.g., A4429) has a valve for draining urine.A locking flange (e.g., A4420) is a lever type flange locking mechanism. It differs from simple push-on pouch securing mechanisms. The mechanism may be incorporated either in the pouch flange or skin barrier flange (2 piece system).PASTES:A paste is used as a protective layer and sealant beneath ostomy appliances, and is applied directly on the skin. It may be primarily pectin based (A4406), or non-pectin based, e.g., karaya (A4405).MISCELLANEOUS:Code A4436 (IRRIGATION SUPPLY; SLEEVE, REUSABLE, PER MONTH) describes an ostomy accessory that is secured around the stoma using a belt or by locking onto a faceplate that is attached to the peristomal skin. They are typically used for a week or more, cleaned and dried between irrigations, before finally being discarded.Code A4437 (IRRIGATION SUPPLY; SLEEVE, DISPOSABLE, PER MONTH) describes an ostomy accessory that is applied directly onto the peristomal skin, and is discarded after each irrigation due to inability to re-adhere to the skin surface.Codes A4436 (IRRIGATION SUPPLY; SLEEVE, REUSABLE, PER MONTH) and A4437 (IRRIGATION SUPPLY; SLEEVE, DISPOSABLE, PER MONTH) describe a monthly supply allowance for irrigation sleeves. No more than 1 unit of service is billable per thirty (30) days.Code A4400 (Ostomy irrigation set) is not valid for claim submission. If an irrigation kit is supplied, the individual components should be billed using individual codes, A4398 and A4399.Ostomy clamps (A4363) are used with drainable pouches and are not used with urinary pouches. Ostomy clamps are only payable when ordered as a replacement. Claims for ostomy clamps billed with ostomy pouches will be denied as not separately payable with ostomy pouches.When codes A4450, A4452, and A5120 are used with ostomy supplies, they must be billed with the AU modifier. For this policy, codes A4450, A4452, and A5120 are the only codes for which the AU modifier may be used.Suppliers should contact the Pricing, Data Analysis, and Coding (PDAC) contractor for guidance on the correct coding of these items.
