## **What is HCPCS code G0316?** G0316 is an HCPCS code maintained by the Centers for Medicare and Medicaid Services (CMS) under Miscellaneous Diagnostic and Therapeutic services, that has a full description of: Prolonged hospital inpatient or observation care evaluation and management service(s) beyond the total time for the primary service (when the primary service has been selected using time on the date of the primary service); each additional 15 minutes by the physician or qualified healthcare professional, with or without direct patient contact (list separately in addition to cpt codes 99223, 99233, and 99236 for hospital inpatient or observation care evaluation and management services). is a Medicare-specific add-on code used by physicians and QHPs to report prolonged Evaluation and Management (E/M) services furnished during a hospital inpatient or observation care visit when the primary E/M level was determined based on total time. The purpose of this code is to provide additional reimbursement for medically necessary time spent beyond the threshold required to bill the highest-level base codes, specifically CPT codes 99223 (Initial), 99233 (Subsequent), or 99236 (Same-day Admit/Discharge). Each billed unit of G0316 represents each additional 15 minutes of total time spent on qualifying activities, which can include non-face-to-face work like documentation, ordering, and coordination. It's crucial that one does not report g0316 for any time unit less than 15 minutes. To add, you must not report G0316 on the same date of service as other prolonged services for evaluation and management codes 99358, 99359, 99418, 99415, 99416.

## **Documentation requirements** When billing G0316, the medical record documentation must support the use of time to select the level of the primary E/M service and must clearly show the total time spent. ### **Total time documentation** The total time spent by the physician or QHP on the date of the encounter must be clearly documented. This time includes both face-to-face and non-face-to-face activities related to the patient's care. ### **Time components** Documentable activities include (but are not limited to): - Preparing to see the patient (e.g., reviewing tests, notes). - Obtaining and/or reviewing separately obtained history. - Performing a medically appropriate examination and/or evaluation. - Counseling and educating the patient/family/caregiver. - Ordering medications, tests, or procedures. - Referring and communicating with other health professionals (when not separately reported). - Documenting clinical information. - Independently interpreting results (not separately reported) and communicating them. Care coordination (not separately reported). ### **Time exclusion** Time spent on services that are reported separately (e.g., procedures) and travel time cannot be counted toward the total time. ### **Medical necessity** Documentation must clearly support the medical necessity and appropriateness of the prolonged service.

### **Billing requirements** To properly bill for HCPCS code G0316, one must consider the following requirements/guidelines: - **Add-on code**: G0316 is used in addition to the primary E/M code when the total time spent on patient care exceeds the time threshold for the highest-level E/M code selected based on time. - **Time-based selection**: The primary E/M code (99223, 99233, or 99236) must have been selected based on the time spent, not Medical Decision Making (MDM). - **Unit increments**: Each unit of G0316 represents 15 additional minutes beyond the threshold time. The full 15-minute increment must be met. - **Medicare specific**: This is a HCPCS Level II code specifically established for Medicare billing of these prolonged services, often serving as the Medicare equivalent to CPT code 99418. - **Discharge services**: G0316 is not reportable in conjunction with codes for hospital inpatient or observation care discharge day management. - **Time counting**: Do not count time spent on services that are separately billed to Medicare.

## **Other relevant codes** - **G0317**: Prolonged nursing facility evaluation and management service(s) beyond the total time for the primary service (when the primary service has been selected using time on the date of the primary service); each additional 15 minutes by the physician or qualified healthcare professional, with or without direct patient contact (list separately in addition to cpt codes 99306, 99310 for nursing facility evaluation and management services). (do not report g0317 on the same date of service as other prolonged services for evaluation and management 99358, 99359, 99418). (do not report g0317 for any time unit less than 15 minutes) - **G0318**: Prolonged home or residence evaluation and management service(s) beyond the total time for the primary service (when the primary service has been selected using time on the date of the primary service); each additional 15 minutes by the physician or qualified healthcare professional, with or without direct patient contact (list separately in addition to cpt codes 99345, 99350 for home or residence evaluation and management services). (do not report g0318 on the same date of service as other prolonged services for evaluation and management 99358, 99359, 99417). (do not report g0318 for any time unit less than 15 minutes) - **G2212**: Prolonged office or other outpatient evaluation and management service(s) beyond the maximum required time of the primary procedure which has been selected using total time on the date of the primary service; each additional 15 minutes by the physician or qualified healthcare professional, with or without direct patient contact (list separately in addition to cpt codes 99205, 99215, 99483 for office or other outpatient evaluation and management services) (do not report g2212 on the same date of service as 99358, 99359, 99415, 99416). (do not report g2212 for any time unit less than 15 minutes)

Frequently asked questions

CMS created G0316 (and others like G2212, G0317, G0318) for Medicare billing to establish its own rules and time thresholds for prolonged E/M services, distinct from the CPT guidelines.

No. The code description explicitly states, "Do not report G0316 for any time unit less than 15 minutes." The total time must equal or exceed the base code time plus the full 15-minute prolonged increment.

No. The descriptor specifies "with or without direct patient contact." It is the total medically necessary time spent by the physician or QHP on the date of the encounter (or within the three subsequent calendar days for 99236).
