PSC M1DZ

Overview

The Product Service Code (PSC) is the federal taxonomy used to classify goods and services for procurement, enabling consistent FPDS/SAM reporting, spend analysis, and procurement management. The PSC list and guidance are maintained in the Product and Service Code Manual on Acquisition.gov, which is the authoritative source for PSC structure and updates.¹

PSC M1DZ — OPERATION OF OTHER HOSPITAL BUILDINGS (M1DZ) is the PSC descriptor applied to procurements for nonclinical, facility-related operation and management of hospital‑associated buildings that are not the principal patient-care hospital or infirmary. Typical use covers administration and facility services for support buildings, not clinical care. The PSC Manual lists M1DZ as a current PSC entry but provides only the code label; agencies define detailed scope in solicitations and statements of work.¹

What this PSC covers

• Nonclinical facility operations for hospital‑associated or support buildings (administration, supply warehouses, clinics without inpatient care).¹
• Building-systems operation and monitoring (HVAC, electrical distribution, domestic water systems) and routine utilities coordination.¹
• Custodial and housekeeping services in nonpatient‑care buildings and common areas supporting hospital operations.¹
• Security, access control, grounds and site-management services for auxiliary hospital facilities.¹
• Minor and preventive maintenance, routine repairs of building fabric and systems when not covered elsewhere in the PSC structure.¹
• Ancillary services such as wayfinding/signage, building utilities coordination, and other support functions defined in a solicitation’s statement of work.¹

Related NAICS and PSC codes

The PSC Manual does not publish a definitive NAICS-to-PSC crosswalk specific to M1DZ; agencies typically select an appropriate NAICS code when soliciting, based on the statement of work and the nature of services required. For crosswalks and solicitation-level mapping, contracting officers reference agency guidance and solicitation requirements rather than a mandated PSC-to-NAICS map in the Manual.¹

Common contracting considerations

• Scope clarity: Statements of work should explicitly separate clinical patient-care tasks (exclude from M1DZ) from nonclinical facility operations to ensure accurate PSC and NAICS reporting and avoid improper scope overlap.¹
• Contract bundling and vehicles: Agencies may pair M1DZ requirements with broader facility‑management vehicles or multiple PSCs (operations, maintenance, repair) depending on contract structure and performance requirements.¹
• Performance metrics and deliverables: Define performance standards for custodial, HVAC, security, and maintenance services in measurable terms (frequency, response times, quality levels) to support oversight and reporting; the PSC Manual provides code labels but not contract templates.¹

Frequently asked questions

• What activities should be classified to PSC M1DZ?
  PSC M1DZ generally covers nonclinical operation and facility management of hospital support buildings—custodial, utilities coordination, site services, and building systems operation. The Manual provides the code label; agencies define the exact activity list in solicitations and SOWs.¹

• How does M1DZ differ from M1DA (Operation of Hospitals and Infirmaries)?
  PSC M1DA is applied to operation of principal hospitals and infirmaries where clinical and inpatient services occur. By contrast, M1DZ is for auxiliary or support buildings without primary patient-care operations. The Manual distinguishes codes by label; agencies define boundaries in procurement documents.¹

• Which agencies commonly use M1DZ?
  Federal health components, veterans’ medical facilities, and facility‑management contracting offices most frequently use PSC M1DZ for nonclinical hospital building operations. The Manual does not enumerate agency‑level usage statistics; those patterns vary by program office and procurement cycles.¹

• Where to find official PSC guidance and change procedures?
  The Product and Service Code Manual on Acquisition.gov is the authoritative source for PSC definitions, maintenance, and change procedures; the Manual index and current PDF versions are published on Acquisition.gov.¹
