Official Description

Hospital mandated on call service; in-hospital, each hour

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

Code 99026 is utilized to document the time a physician is required to be on call while physically present in the hospital. This code is specifically applicable for each hour that the physician is available to respond to patient needs or emergencies within the hospital setting. It is important to note that this code does not encompass any time spent on other billable services or procedures that the physician may perform during this on-call period. The distinction between being on call in the hospital versus being on call outside the hospital is critical, as it affects the appropriate coding and billing practices. For instance, code 99027 is designated for situations where the physician is on call but not physically present in the hospital. Understanding these nuances is essential for accurate medical coding and ensuring compliance with billing regulations.

1. Indications

The use of CPT® code 99026 is indicated in scenarios where a physician is mandated to be on call while present in the hospital. This typically applies to situations where the hospital requires the physician to be available for immediate response to patient care needs, emergencies, or other critical situations that may arise during their on-call hours. The following conditions may warrant the use of this code:

  • Hospital Policy Requirement Physicians are required to be on call as per hospital regulations to ensure patient safety and timely medical intervention.
  • Emergency Situations The physician must be available to address urgent medical needs that may arise unexpectedly during their on-call hours.
  • Patient Care Needs The physician's presence is necessary to provide immediate care or consultation for patients admitted to the hospital.

2. Procedure

The procedure associated with CPT® code 99026 involves the following steps:

  • Step 1: On-Call Requirement The physician is notified of their on-call requirement by the hospital administration, which outlines the specific hours they are expected to be available within the hospital premises.
  • Step 2: Availability During the designated on-call hours, the physician must remain in the hospital, ready to respond to any patient care needs or emergencies that may arise. This includes being accessible for consultations, assessments, or interventions as necessary.
  • Step 3: Documentation The physician must accurately document the hours spent on call in the hospital, ensuring that the time is recorded in compliance with hospital policies and coding guidelines. This documentation is crucial for billing purposes and to justify the use of code 99026.

3. Post-Procedure

After the on-call period has concluded, the physician may transition to other responsibilities or procedures as required. It is essential for the physician to maintain accurate records of their on-call hours for billing and compliance purposes. Additionally, any patient interactions or services provided during the on-call period should be documented separately, as they may be eligible for separate billing under appropriate CPT® codes. The physician should also review any follow-up care or consultations that may be necessary for patients they attended to during their on-call hours.

25 Significant, separately identifiable evaluation and management service by the same physician or other qualified health care professional on the same day of the procedure or other service: it may be necessary to indicate that on the day a procedure or service identified by a cpt code was performed, the patient's condition required a significant, separately identifiable e/m service above and beyond the other service provided or beyond the usual preoperative and postoperative care associated with the procedure that was performed. a significant, separately identifiable e/m service is defined or substantiated by documentation that satisfies the relevant criteria for the respective e/m service to be reported (see evaluation and management services guidelines for instructions on determining level of e/m service). the e/m service may be prompted by the symptom or condition for which the procedure and/or service was provided. as such, different diagnoses are not required for reporting of the e/m services on the same date. this circumstance may be reported by adding modifier 25 to the appropriate level of e/m service. note: this modifier is not used to report an e/m service that resulted in a decision to perform surgery. see modifier 57 for significant, separately identifiable non-e/m services, see modifier 59.
