Local Coverage Determination (LCD)

A Local Coverage Determination (LCD) is a Medicare Administrative Contractor (MAC) published coverage policy that defines whether a specific service or item is covered under Medicare in the MAC's geographic jurisdiction, including the medical necessity criteria, documentation requirements, and coding specifications. LCDs supplement National Coverage Determinations (NCDs) issued by CMS centrally. Medicare contractor audits (UPIC, RAC, MAC, SMRC, CERT) verify claims against the applicable LCD in force on the date of service.

How LCDs work

Each MAC develops LCDs for services and items within its jurisdiction following the CMS LCD development framework: clinical review, evidence assessment, draft publication, comment period, advisory committee input, and final publication. LCDs operate at the date-of-service level: the LCD in force on the date the service was provided is the applicable LCD, regardless of subsequent revisions. Contractors publish the LCD identifier (a defined format with a numeric identifier and the relevant codes) and the effective dates so that providers can verify the controlling policy.

Audit findings driven by LCD compliance include: claims for services not covered under the applicable LCD, claims missing the documentation the LCD requires, claims for the wrong CPT or HCPCS code under the LCD's coding framework, and claims for services performed by prescriber specialties outside the LCD's coverage scope. Each finding category supports recoupment under 42 CFR Part 405, and where the LCD violations support knowledge or reckless disregard theories, FCA exposure attaches.

When LCDs apply

LCDs apply to Medicare fee-for-service claims in the relevant MAC jurisdiction. Medicare Advantage plans typically incorporate the applicable LCD into the plan's medical-necessity framework, with variation by plan. Medicaid coverage may operate on state-specific policies that may or may not parallel the Medicare LCD framework. The 2026 CMS reclassification of skin substitutes and the wound care LCD revisions are central to current wound care enforcement.

The provider's exposure under LCD-driven findings

Per-claim recoupment runs through the standard Medicare framework, with statistical extrapolation available across the claim universe. FCA exposure surfaces where the audit findings support knowledge or reckless disregard. The defense framework focuses on the date-of-service LCD verification (the right LCD version applied), the documentation match (contemporaneous clinical records aligned with LCD requirements), and the appeal record at the QIC and ALJ stages where the LCD interpretation is contested.
