Medicare Claims Processing Manual (Pub. 100-04), Ch. 12 § 30.6.12.4
Critical Care Furnished Concurrently by Practitioners in the
30.6.12.4 - Critical Care Furnished Concurrently by Practitioners in the
Same Specialty and Same Group (Follow-Up Care)
(Rev. 11288; Issued: 03-04-22; Effective: 01-01-22; Implementation: 02-15-22)
Physician(s) or NPP(s) in the same specialty and in the same group may provide concurrent
follow-up care, such as a critical care visit subsequent to another practitioner’s critical care
visit. This may be as part of continuous staff coverage or follow-up care to critical care
services furnished earlier in the day on the same calendar date.
In the situation where a practitioner furnishes the initial critical care service in its entirety and
reports CPT code 99291, any additional practitioner(s) in the same specialty and the same
group furnishing care concurrently to the same patient on the same date report their time using
the code for subsequent time intervals (CPT code 99292). CPT code 99291 will not be reported
more than once for the same patient on the same date by these practitioners. This policy
recognizes that multiple practitioners in the same specialty and the same group can maintain
continuity of care by providing follow-up care for the same patient on a single date.
When one practitioner begins furnishing the initial critical care service, but does not meet the
time required to report CPT code 99291, another practitioner in the same specialty and group
can continue to deliver critical care to the same patient on the same date. The total time spent
by the practitioners is aggregated to meet the time requirement to bill CPT code 99291. Once
the cumulative required critical care service time is met to report CPT code 99291, CPT code
99292 can only be reported by a practitioner in the same specialty and group when an
additional 30 minutes of critical care services have been furnished to the same patient on the
same date (74 minutes + 30 minutes = 104 total minutes).
The aggregated time spent on critical care visits must be medically necessary and each visit
must meet the definition of critical care in order to add the times for purposes of meeting the
time requirement to bill CPT code 99291.
For purposes of payment under the Physician Fee Schedule, Medicare classifies NPPs in a
specialty that is not the same as a physician with whom the NPP is working, so the policies
above would not apply to the situation where an NPP provides the follow-up care to a
physician, or vice versa. Instead, see the section below regarding split (or shared) critical care
services.
