Subsequent Observation Care

In
the instance that a patient is held in observation status for more than
two calendar dates, the supervising physician should utilize a
subsequent Observation Care CPT code (99224-99226). Physicians other
than the supervising physician providing care to a patient designated as
“observation status” should report subsequent Observation Care. 
According to the CPT codebook, “All levels of subsequent Observation
Care include reviewing the medical record and reviewing the results of
diagnostic studies and changes in the patient’s status (i.e., changes in
history, physical conditions, and response to management) since the
last assessment.”

Observation Care Discharge Services

Per
CPT, Observation Care discharge day management CPT code 99217 “includes
final examination of the patient, discussion of the hospital stay,
instructions for continuing care and preparation of discharge records.”
Observation Care discharge services include all E/M services on the date
of discharge from observation services and should only be reported if
the discharge from observation status is on a date other than the date
of initial Observation Care.

Oxford follows CMS guidelines that
physicians should not report an Observation Care discharge Service when
theObservation Care is a minimum of 8 hours and less than 24 hours and
the patient is discharged on the same calendar date.

Observation
Care Admission and Discharge Services on Same Date Physicians who admit a
patient to Observation Care for a minimum of 8 hours, but less than 24
hours and subsequently discharge on the same calendar date shall report
an Observation or Inpatient Care Service (Including  Admission and
Discharge Services) CPT code (99234-99236).

CMS’ Claims Processing Manual, when reporting an Observation Care
admission and discharge service CPT code (99234-99236) the medical

Question and answers

Q:
What code should be reported for a patient who continues to be in
observation status for a second date and has not been discharged?

A: A
subsequent Observation Care CPT code (99224-99226) should be reported
in the instance a patient is held in observation status for more than 2
calendar dates. When observation discharge services are provided to the
patient, report CPT code 99217 on that calendar date. For example,
report CPT 99218- 99220 for a patient designated as observation on Day
1, report CPT 99224-99226 on Day 2 and finally report CPT 99217 when the
patient receives discharge services on Day 3.

Q: Why are Observation Codes G0378 and G0379 not addressed in this policy ?
A:
These HCPCS codes are not to be reported for physician services. These
codes are to be billed by facilities on a UB-04 claim form.

Emergency
department visits will be denied when billed on the same day as an
observation service (procedure codes 1-99217, 1-99218, 1-99219, and
1-99220) by the same provider.
