99253 CPT Code Description

New or established patient Inpatient consultation for a new or established patient requires these three key elements: An appropriate detailed history, A detailed examination, and medical decision-making of low complexity. 

Coordination of care and Counseling with other providers or agencies are provided consistent with the nature of the problem and the patient’s or his family’s demand. Usually, the presenting problems are of moderate intensity or severity. Typically, 55 minutes are spent at the patient’s hospital unit or bedside.

99253 CPT code is the third-highest level of care for hospital consults.

Inpatient consultation service codes describe encounters with patients admitted to the hospital, residing in nursing facilities, or patients in a partial hospital setting where another qualified clinician’s advice or opinion regarding diagnosis and treatment or determination to accept the transfer of care of a patient are rendered at the request of the primary treating provider. 

The consultation request must be documented in the patient’s medical record and a confirmed report of the consultation findings to the primary treating physician. The physician consultant can initiate diagnostic or therapeutic services during a consultation or follow-up visit at the same encounter.

Other procedures or services performed with the consultation may be reported separately. Only one inpatient consultation services code should be written per admission, and CPT codes do not differentiate between new or established patients. Services are reported based on meeting all three key components (history, exam, and medical decision-making) within each level of service. 

As represented by 99251, the most basic service describes a problem-focused history and exam with straightforward medical decision-making for a minor or self-limiting complaint encompassing approximately 20 minutes at the patient’s bedside or on the unit. 

The mid-level services describe problems involving an expanded problem-focused history and exam or a detailed history and exam represented by 99252 and 99253 CPT code, respectively.

Medical decision-making for 99252 is the same (straightforward) as for a level one visit (99251) and is designated as low complexity for the level three service (99253). At these service levels, the encounter can involve time at the patient’s bedside or on the unit of 40 (99252) to 55 (CPT code 99253) minutes involving minimal to low severity concerns.

These codes are used to report consultations in the inpatient setting. All three key elements (history, exam, and medical decision-making) should be equal to or exceeded for the level of E&M service selected.

Consultation code 99253 is not covered by Medicare and some payers. Report new or established inpatient E/M codes for consultation services. Consultation services should not be reported when the care and management of a problem or condition are assumed before the patient’s initial examination.

Do not report inpatient and outpatient consultation codes when both are related to the same inpatient admission.
