MAC contractor coverage
Inpatient (IPPS) billing is subject to both national CMS policy and regional MAC contractor Local Coverage Determinations (LCDs). Coverage from all seven A/B contractors — Noridian, CGS, First Coast, NGS, Novitas, Palmetto GBA, and WPS — reaches us through the CMS Medicare Coverage Database, where they publish their LCDs and Billing & Coding Articles; we track it there for updates affecting Inpatient (IPPS) codes. Coverage criteria vary by contractor jurisdiction.

Weekly digest of CMS and MAC policy changes for Inpatient (IPPS) billing teams.
Inpatient (IPPS) billing is subject to regional Local Coverage Determinations (LCDs) from the 7 A/B Medicare Administrative Contractors: Noridian, CGS Administrators, First Coast Service Options, National Government Services, Novitas Solutions, Palmetto GBA, and WPS Government Health Administrators. Between them they administer the 12 A/B MAC jurisdictions; a further 4 DME MAC jurisdictions are administered by Noridian and CGS. Coverage criteria and medical necessity requirements vary by jurisdiction. CLV Intelligence monitors all 16 MAC jurisdictions daily for LCD updates affecting Inpatient (IPPS) codes.
CMS updates the Physician Fee Schedule annually, effective January 1, with proposed rules published in the summer and final rules in November. MAC contractors issue LCD updates on a rolling basis throughout the year with no fixed schedule. The Federal Register publishes proposed and final rules affecting Inpatient (IPPS) reimbursement on a continuous basis. CLV Intelligence monitors all three sources daily and surfaces updates by signal strength.
A Local Coverage Determination (LCD) is a decision by a Medicare Administrative Contractor specifying under what clinical circumstances a particular service is covered within its geographic jurisdiction. For Inpatient (IPPS) billing teams, LCDs define medical necessity criteria, covered diagnoses, and documentation requirements for specific procedures. Failure to comply with LCD requirements is among the most common causes of Medicare claim denial in Inpatient (IPPS) practices.
