Time and Medical Decision Making Levels for Evaluation and Management Services

Find the total time and medical decision making levels for a variety of E/M codes and service areas. 

Have questions about how and when to use total time or MDM?


Office or Other Outpatient Services

Total time and MDM do not apply to 99211. CPT code 99211 is intended for the evaluation and management of a patient that may not require the presence of a physician or other QHP.

Inpatient and Observation Care Services

The observation CPT codes (99217, 99218, 99219, 99220, 99224, 99225, 99226) have been deleted and merged into the existing hospital care CPT codes.

Initial vs. subsequent is determined based on whether the patient has received any professional services from the physician or other QHP or another physician or other QHP of the exact same specialty and subspecialty who belongs to the same group practice during the stay. This is like the new vs. established patient definitions, except the determining factor is related to the stay rather than the past three years.

99239

Time includes total time on the date of the encounter.  

Hospital Inpatient or Observation Care Services require that the patient be admitted and discharged on the same date of service and the stay must be at least eight hours. Only the physician or QHP who performs both the initial and discharge service may report these services. When a patient receives hospital inpatient or observation care services for fewer than eight hours, use the initial hospital inpatient or observation care codes (CPT codes 99221-99223). 


Consultation Services

Most of the guidelines for the consultation codes remain the same. Code descriptors have been edited to reflect the revised MDM and time requirements. Note: Medicare does not cover consultation codes.

Emergency Department Services

Time cannot be used to select the level of service for emergency department visits. The level of service is based on MDM. This does not differ from the previous guideline. However, the MDM levels have been modified to align with those for office visits.

Nursing facility discharge services require a face-to-face encounter with the patient and/or family/caregiver that may be performed on a date prior to the date the patient leaves the facility. The level of service should be selected based on the total time on the date of the face-to-face discharge management encounter. 

The CPT code for annual nursing facility assessment (CPT code 99318) has been deleted. These services can be reported using the subsequent nursing facility care services (CPT codes 99307-99310) or Medicare G codes.

The CPT Panel established a high-level MDM type specific to initial nursing facility care by the principal physician or other QHP that takes into account the number and complexity of problems addressed. This type is: "Multiple morbidities requiring intensive management: A set of conditions, syndromes, or functional impairments that are likely to require frequent medication changes or other treatment changes and/or re-evaluations. The patient is at significant risk of worsening medical (including behavioral) status and risk for (re)admission to a hospital.” 

A principal physician is sometimes referred to as the admitting physician and is the individual who oversees the patient’s care. This is different from other physicians or other QHPs who may be furnishing specialty care. 

Initial vs. subsequent is determined based on whether the patient has received any professional services from the physician or other QHP or another physician or other QHP of the exact same specialty and subspecialty who belongs to the same group practice during the stay. This is like the new vs. established patient definitions, except the determining factor is related to the stay rather than the past three years.
