Medical Record Documentation
30.6.12.8 - Medical Record Documentation
(Rev. 11288; Issued: 03-04-22; Effective: 01-01-22; Implementation: 02-15-22)
Critical care is a time-based service, and therefore, practitioners must document in the medical
record the total time (not necessarily start and stop times) that critical care services are
furnished by each reporting practitioner. Documentation needs to indicate that the services
furnished to the patient, including any concurrent care by the practitioners, are medically
reasonable and necessary for the diagnosis and/or treatment of illness and/or injury or to
improve the functioning of a malformed body member.
To support coverage and payment determinations regarding concurrent care, services must be
sufficiently documented to allow a medical reviewer to determine the role each practitioner
played in the patient’s care (that is, the condition or conditions for which the practitioner
treated the patient).
When critical care services are reported the same date as another E/M visit, the medical record
documentation must support: 1) that the other E/M visit was provided prior to the critical care
services at a time when the patient did not require critical care, 2) that the services were
medically necessary, and 3) that the services were separate and distinct, with no duplicative
elements from the critical care services provided later on that date.
When critical care services are furnished in conjunction with a global procedure, the medical
record documentation must support that the critical care was unrelated to the procedure, as
discussed above.
To support coverage and payment determinations regarding split (or shared) critical care
services, the documentation requirements for all split (or shared) E/M visits apply to critical
care visits also (see section 30.6.18).
