Part B Insider (Multispecialty) Coding Alert

If you think you might be at risk of making place of service (POS) errors like the OIG found in its recent audit, keep the following list close at hand so you know exactly which codes apply to each location.

• 11 (Office) -- Location, other than a hospital, skilled nursing facility (SNF), military treatment facility, community health center, state or local public health clinic, or intermediate care facility (ICF), where the health professional routinely provides health examinations, diagnosis and treatment of illness or injury on an ambulatory basis. Fair market value for the office must be paid for this office to qualify for an office and POS 11.

• 21 (Inpatient hospital) -- A facility, other than psychiatric, that primarily provides diagnostic, therapeutic (both surgical and nonsurgical) and rehabilitation services by, or under, the supervision of physicians to patients admitted for a variety of medical conditions.

• 23 (Emergency room -- hospital)-- A portion of a hospital where emergency diagnosis and treatment of illness or injury is provided.

• 24 (Ambulatory surgical centers)—A freestanding facility, other than a physician’s office, where surgical and diagnostic services are provided on an ambulatory basis.

• 31 (Skilled nursing facility) -- A facility that primarily provides inpatient skilled nursing care and related services to patients who require medical, nursing or rehabilitative services but does not provide the care level or treatment available in a hospital.

• 32 (Nursing facility) -- A facility that primarily provides to residents skilled nursing care and related services for the rehabilitation of injured, disabled, or sick persons, or, on a regular basis, health-related care services above the level of custodial care to other than mentally retarded individuals.

• 33 (Custodial care facility) -- A facility that provides room, board and other personal assistance services, generally on a long-term basis, and does not include a medical component.
