Official Description

Services provided in the office at times other than regularly scheduled office hours, or days when the office is normally closed (eg, holidays, Saturday or Sunday), in addition to basic service

Common Language Description

The CPT® Code 99050 refers to services rendered in a medical office during times that fall outside of the standard office hours or on days when the office is typically closed. This includes services provided on weekends, holidays, or any other time that is not part of the regular schedule. The code is utilized to indicate that the healthcare provider is delivering basic medical services under these special circumstances, which may require additional considerations for scheduling and staffing. The use of this code helps to ensure that healthcare providers are appropriately compensated for the extra effort and resources involved in providing care during non-standard hours, thereby recognizing the unique challenges associated with such services.

1. Indications

The use of CPT® Code 99050 is indicated for services provided in the office during non-standard hours or on days when the office is normally closed. This may include situations such as:

  • After-Hours Care Services rendered after the regular office hours, which may be necessary for urgent patient needs.
  • Weekend Services Medical services provided on Saturdays or Sundays when the office is typically not open.
  • Holiday Services Care offered on recognized holidays when the office is usually closed to patients.

2. Procedure

The procedural steps associated with the use of CPT® Code 99050 involve the following:

  • Step 1: Scheduling The healthcare provider or office staff must schedule the appointment for the patient during the non-standard hours or on a closed day. This requires coordination to ensure that the necessary resources and personnel are available to provide care.
  • Step 2: Patient Arrival Upon the patient's arrival, the office staff should verify the appointment and ensure that all necessary documentation is in order, including any pre-visit instructions that may have been provided to the patient.
  • Step 3: Provision of Services The healthcare provider delivers the necessary medical services to the patient, which may include examinations, consultations, or other basic procedures as required. The provider must document the services rendered, noting the special circumstances under which they were provided.
  • Step 4: Billing and Coding After the services are completed, the office staff must accurately code the visit using CPT® Code 99050 to reflect that the services were provided outside of regular office hours. This ensures proper billing and reimbursement for the additional effort involved.

3. Post-Procedure

Post-procedure care following the use of CPT® Code 99050 may include standard follow-up instructions provided to the patient, which could involve monitoring for any adverse effects from the services rendered. Additionally, the healthcare provider may schedule a follow-up appointment during regular office hours to ensure continuity of care. Documentation of the visit should be completed promptly to facilitate billing and to maintain accurate patient records. It is also important for the office to review any specific policies regarding after-hours care to ensure compliance with any applicable regulations.

95 Synchronous telemedicine service rendered via a real-time interactive audio and video telecommunications system: synchronous telemedicine service is defined as a real-time interaction between a physician or other qualified health care professional and a patient who is located at a distant site from the physician or other qualified health care professional. the totality of the communication of information exchanged between the physician or other qualified health care professional and the patient during the course of the synchronous telemedicine service must be of an amount and nature that would be sufficient to meet the key components and/or requirements of the same service when rendered via a face-to-face interaction. modifier 95 may only be appended to the services listed in appendix p. appendix p is the list of cpt codes for services that are typically performed face-to-face, but may be rendered via a real-time (synchronous) interactive audio and video telecommunications system.
XS Separate structure, a service that is distinct because it was performed on a separate organ/structure
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
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.
GY Item or service statutorily excluded, does not meet the definition of any medicare benefit or, for non-medicare insurers, is not a contract benefit
GT Via interactive audio and video telecommunication systems
22 Increased procedural services: when the work required to provide a service is substantially greater than typically required, it may be identified by adding modifier 22 to the usual procedure code. documentation must support the substantial additional work and the reason for the additional work (ie, increased intensity, time, technical difficulty of procedure, severity of patient's condition, physical and mental effort required). note: this modifier should not be appended to an e/m service.
24 Unrelated evaluation and management service by the same physician or other qualified health care professional during a postoperative period: the physician or other qualified health care professional may need to indicate that an evaluation and management service was performed during a postoperative period for a reason(s) unrelated to the original procedure. this circumstance may be reported by adding modifier 24 to the appropriate level of e/m service.
51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
57 Decision for surgery: an evaluation and management service that resulted in the initial decision to perform the surgery may be identified by adding modifier 57 to the appropriate level of e/m service.
58 Staged or related procedure or service by the same physician or other qualified health care professional during the postoperative period: it may be necessary to indicate that the performance of a procedure or service during the postoperative period was: (a) planned or anticipated (staged); (b) more extensive than the original procedure; or (c) for therapy following a surgical procedure. this circumstance may be reported by adding modifier 58 to the staged or related procedure. note: for treatment of a problem that requires a return to the operating/procedure room (eg, unanticipated clinical condition), see modifier 78.
79 Unrelated procedure or service by the same physician or other qualified health care professional during the postoperative period: the individual may need to indicate that the performance of a procedure or service during the postoperative period was unrelated to the original procedure. this circumstance may be reported by using modifier 79. (for repeat procedures on the same day, see modifier 76.)
93 Synchronous telemedicine service rendered via telephone or other real-time interactive audio-only telecommunications system : synchronous telemedicine service is defined as a real-time interaction between a physician or other qualified health care professional and a patient who is located away at a distant site from the physician or other qualified health care professional. the totality of the communication of information exchanged between the physician or other qualified health care professional and the patient during the course of the synchronous telemedicine service must be of an amount and nature that is sufficient to meet the key components and/or requirements of the same service when rendered via a face-to-face interaction.
