Compression stockings are specialized medical devices that apply graduated pressure to the limbs to support venous and lymphatic health. These garments are prescribed to manage conditions like chronic venous insufficiency, which impairs blood flow back to the heart, or to help prevent deep vein thrombosis (DVT). Since Medicaid is a joint federal and state program, a straightforward yes or no answer regarding coverage is not possible. The complexity arises from mandatory federal guidelines combined with significant state-level flexibility in administering and defining coverage for medical supplies.
General Coverage Requirements
Medicaid offers coverage for Durable Medical Equipment (DME), defined as equipment that can withstand repeated use and is primarily medical in nature. Compression stockings can fall under this DME category, but they must meet the standard of “medical necessity” to be covered. Medical necessity means the item is required to treat a specific, documented condition, as determined by a healthcare provider.
For coverage to be considered, the prescription for the compression garment must identify a specific diagnosis and the required amount of compression. Conditions that often qualify include chronic lymphedema, venous stasis ulcers, severe edema, post-thrombotic syndrome, and certain complications during pregnancy. Coverage is generally limited to therapeutic-grade garments, often those with a compression level of 18 mmHg or higher. The stockings must be part of a formal medical treatment plan, not for general comfort or prevention.
The Role of State Medicaid Programs
The federal government sets minimum requirements for Medicaid, but each state administers its own program under Title XIX of the Social Security Act. States have significant latitude in determining which services beyond the mandatory federal minimums they will cover. Compression stockings are often classified as an optional benefit, meaning states can decide the extent of their coverage or choose to limit it to specific medical circumstances.
This state-by-state variation means that a Medicaid beneficiary’s coverage depends entirely on their physical location. Some state programs may cover the garments broadly for any medically necessary condition, while others may restrict coverage to very specific diagnoses like lymphedema or the presence of an open venous stasis ulcer. States may also utilize managed care organizations (MCOs) to administer benefits, and these MCOs can have slightly different authorization policies than the state’s fee-for-service program.
Securing Coverage Through Prior Authorization
The process for obtaining covered compression stockings is procedural and requires specific administrative steps, beginning with the prescribing physician. A signed and dated prescription is required, which must clearly identify the patient’s diagnosis, the exact type of garment needed, and the prescribed compression amount. This prescription often serves as the initial evidence of medical necessity.
The next step frequently involves a process called Prior Authorization (PA) or pre-approval from the state Medicaid agency or the managed care organization. This is a formal review where the insurer determines if the request meets their specific coverage criteria before the item is dispensed. Documentation requirements can be extensive, often including circumferential and length measurements for proper fitting, diagnosis codes, and sometimes evidence that alternative treatments have been unsuccessful. Once approved, coverage typically specifies a limit on the number of garments, such as three pairs per member per year.
Exclusions and Non-Covered Types of Stockings
Medicaid coverage for compression garments is highly specific and excludes certain types of hosiery based on their pressure level and intended use. Generally, only high-pressure, gradient compression stockings are covered, which are designed to provide a specific, graduated pressure to the limb. These are typically stockings with a pressure rating of 18-30 mmHg or higher, which require a prescription and professional fitting.
Medicaid typically does not cover over-the-counter (OTC) compression socks or hosiery, even if they offer mild compression. Garments with a pressure of less than 18 mmHg, such as standard elastic stockings, surgical leggings, or low-level preventative socks, are excluded from coverage. These items are considered personal care or general health supplies rather than medically necessary Durable Medical Equipment. The exclusion also applies to compression socks purchased for preventative purposes, such as to reduce swelling during travel.
