CPT 99239 represents the higher-level hospital discharge management code, used when the physician spends more than 30 minutes managing the final discharge of a hospitalized or observation patient. It is the counterpart to 99238 (30 minutes or less). Since the 2023 CPT restructuring, both codes apply uniformly to inpatient and observation patients—the prior observation-only discharge code (99217) was deleted.
Discharge day management is a uniquely time-driven service. Unlike subsequent hospital visit codes (99231–99233), there is no MDM pathway for 99239.
The code is selected based solely on how long the physician personally spent on discharge-related activities on the date of the encounter. This makes thorough, explicit time documentation both critical and non-negotiable.

CPT 99239 is selected exclusively by time. The CPT manual states clearly: discharge management codes 99238 and 99239 are time-based only. To report 99239, the physician must spend more than 30 minutes on the date of the encounter on discharge-related activities. Time need not be continuous—it can be accumulated throughout the day, as long as all time counted is on the same calendar date and personally performed by the physician.
Per CPT 2025/2026 guidelines (unchanged for 2026), the following physician activities count toward the total time threshold :
Critical Exclusions — Do not include the following in your time statement:
The “More Than 30 Minutes” Trap: Documenting exactly “30 minutes” or “approximately 30 minutes” is insufficient for CPT 99239. The code requires the threshold be exceeded. Your note must reflect something like “31 minutes,” “35 minutes,” or “approximately 40 minutes.” Documentation auditors consistently flag vague time statements, and this is the #1 reason 99239 is downgraded to 99238 on audit.
The CPT descriptor defines 99239 as the physician’s total time on the date of encounter for final hospital or observation discharge. Specifically, the code covers all of the following services when performed on the day of discharge :
Because all of these services are bundled into the single discharge code, the attending physician cannot separately bill for prescription writing, referral completion, or discharge instruction time under other codes on the same day. The discharge code encompasses all E/M work by the attending on the date of discharge.
The most common reason 99239 is denied, downgraded, or recouped on audit is inadequate or ambiguous time documentation. Based on FCSO Medicare improper payment findings, the two primary deficiencies are: (1) no time statement at all, and (2) a time statement that does not clearly exceed 30 minutes. The following standards make a note audit-resistant.
Instead of: “Patient discharged home. Discharge instructions given. 30 minutes spent.”
Write: “Patient examined at bedside. Final examination performed; wound healing appropriately, no signs of infection. Discharge instructions reviewed with patient and spouse, including medication changes (new anticoagulant started, NSAID discontinued), activity restrictions, follow-up with PCP within 7 days, and return precautions. Discharge summary dictated, prescription for rivaroxaban provided, and referral form completed for cardiology follow-up. Total time personally spent on discharge activities today: 38 minutes.”
If a resident performs part of the discharge under supervision, the attending must document personal involvement in and oversight of the key portions of the discharge. Under Teaching Physician rules, the attending’s note must reflect their personal participation. Modifier GC is required on the claim. The time counted for code selection must reflect the teaching physician’s personal time, not the resident’s time.
Per CMS guidelines and CPT, only one physician may bill the hospital discharge management service per patient per hospital stay—and it must be the attending/admitting physician of record, or a designated covering physician.
If the admitting physician’s partner performs the discharge due to call coverage or scheduling, billing under the discharging physician’s NPI is appropriate, provided the care was formally transferred or the discharging physician is covering for the same group. The billing date must reflect the actual date of the face-to-face discharge visit.
Consultants and specialists who did not admit the patient CANNOT bill 99239, even if they visit the patient on the discharge date. A cardiologist seeing a patient for rounds on the day of discharge bills a subsequent inpatient visit (99231–99233), not a discharge code. Only the attending physician of record performing the actual discharge process bills 99238 or 99239.
In the event of patient death, the physician who personally performs the pronouncement of death may bill 99238 or 99239 for that service. The billing date must reflect the calendar date on which the pronouncement was performed, even if paperwork is finalized on a subsequent date.
Only one hospital discharge day management service (99238 or 99239) is payable per patient, per hospital stay. If a patient is readmitted within the same hospitalization (e.g., transferred to ICU and back to floor), only one discharge management service is payable for the final discharge of that stay. Medicare will deny a second 99239 for the same admission.
If the patient is both admitted and discharged on the same calendar date with a minimum of 8 hours of hospital care, use CPT 99234–99236 (Hospital Inpatient or Observation Care Services, including admission and discharge on the same date). Do not use 99239 in this scenario. If admission and discharge are on the same day but fewer than 8 hours elapsed, use the appropriate initial care code (99221–99223) only.
The discharge code replaces any subsequent hospital visit code on the day of discharge. The attending physician cannot bill both 99232 and 99239 on the same date of service. The discharge code covers all E/M services provided by the attending on that day. If time spent reviewing labs, making medication decisions, and completing the physical discharge pushes the encounter over 30 minutes in total, 99239 is the appropriate and only E/M code for the day.
When a patient is discharged from a hospital and admitted to a skilled nursing facility on the same day, Medicare will pay both the hospital discharge code (99238 or 99239) and the SNF initial care code when billed by the same physician with the same date of service. These are considered distinct and separately payable services.
Since CPT’s 2023 restructuring, the old observation discharge code (99217) has been deleted. CPT 99238 and 99239 now apply to both inpatient and observation discharges uniformly—eliminating the prior need to distinguish between the two status types when coding the discharge event. If the patient was in observation status and was never formally admitted as inpatient, 99239 still applies when the discharge time exceeds 30 minutes and the discharge occurs on a date other than the observation admission date.
For CY 2026, CMS established two separate conversion factors for the first time: $33.57 for qualifying APM participants and $33.40 for all other physicians, representing increases of 3.77% and 3.26% respectively over 2025. Importantly, E/M codes—including 99238 and 99239—are exempt from CMS’s new 2.5% efficiency adjustment applied to non-time-based procedural codes. This means discharge management code reimbursements are positively impacted by the conversion factor increase without any offsetting downward efficiency adjustment.
While 99239 is a time-based code and does not require a specific diagnosis to qualify, the following ICD-10 codes are frequently associated with discharges that legitimately exceed 30 minutes due to their inherent complexity, required patient education, or extensive care coordination needs:
A surgeon who is also the attending physician may need to use Modifier 24 when the discharge service relates to a problem that is entirely unrelated to the surgical procedure being managed under a global period. Example: An orthopedic surgeon who admitted a patient for a hip replacement is also the attending managing a concurrent pneumonia that complicates the discharge. If the discharge is driven primarily by the unrelated medical problem, Modifier 24 appended to 99239 signals to payers that this is outside the global surgical package. Routine post-op follow-up within the global period is not separately billable.
Modifier 25 would be applicable in the rare scenario where a distinct, separately identifiable procedure (e.g., removal of a chest tube, wound debridement) is performed on the same day as the discharge. In this case, Modifier 25 appended to 99239 signals that the discharge management service was a significant, separately identifiable E/M service beyond the procedural service performed that day. Time counted for 99239 must not overlap with the time/work captured under the procedure code.
When a resident is involved in the discharge under supervision of the teaching physician, Modifier GC must be appended to 99239. The teaching physician must document their personal presence for the key portions of the discharge (the physical examination, discussion with patient, and discharge plan), and the time documented for code selection must reflect only the teaching physician’s personal time, not the resident’s independent time.
When a discharge is performed as a split/shared service by a physician and a non-physician practitioner (NPP) in the same group, Modifier FS must be appended to the claim for Medicare. The code is billed under the provider who performed the substantive portion (more than 50% of the total time, or the provider who made/approved the medical decision making and plan).
Beginning January 1, 2024, both CMS and CPT aligned their definitions for split/shared E/M services. These rules remain unchanged for 2025 and 2026. For discharge codes, split/shared billing follows the same substantive-portion framework applied to other hospital E/M codes.
The provider who performed the substantive portion bills 99239. The substantive portion is defined as either:
Because 99239 is inherently time-based, time is typically the most relevant substantive-portion determination method for split/shared discharge encounters. If the NPP spent 25 minutes and the physician spent 10 minutes, the NPP would be the appropriate billing provider (NPP rate applies). If the physician spent 20 minutes and the NPP spent 15 minutes, the physician bills and Modifier FS is required for Medicare claims.
Important: Medicare requires that both the physician and NPP be enrolled in Medicare and have E/M services within their scope of practice. The note must reflect which provider performed which activities and each provider’s time contribution. A physician’s signature alone on a shared note is not sufficient documentation for billing at the physician rate.
| Code | Time Threshold | Scenario | Key Rules |
|---|---|---|---|
| 99238 | 30 minutes or less on the date of the encounter | Routine, straightforward discharge. Patient is medically stable, instructions are brief, minimal coordination needed. Discharge summary short. Prescriptions reviewed quickly. | Time does NOT need to be explicitly documented. No time threshold to prove — any discharge activity on the date qualifies. Face-to-face required. |
| 99239 | More than 30 minutes on the date of the encounter | Complex discharge requiring extensive patient/family counseling, multiple prescription adjustments, care coordination (SNF, home health, specialist follow-ups), lengthy discharge summary, or complex social barriers to discharge. | Time must be explicitly documented as exceeding 30 minutes. “More than 30 minutes” or the exact total (e.g., “38 minutes”) is required. This is the most common audit deficiency. |
| 99234–99236 | MDM-based (Straightforward/Low, Moderate, or High) or Time-based (45, 70, or 85+ minutes) | Patient admitted and discharged on the same calendar date with a minimum of 8 hours in observation or inpatient status. | Only the principal physician of record who wrote both the admission and discharge notes bills this code set. Cannot be used when the patient was in observation fewer than 8 hours on a single date. |
Patient: 74-year-old discharged after 5-day admission for acute on chronic systolic heart failure decompensation. Activities on Discharge Day: Physician reviews morning BNP and renal function (10 min), performs final bedside exam (8 min), counsels patient and daughter on new medication regimen — furosemide dose increase, new spironolactone, metoprolol titration, ARNI transition (12 min), completes discharge summary and medication reconciliation in EHR (8 min). Total time: 38 minutes. Documentation: “Total physician time spent on discharge activities today: 38 minutes, including chart review, bedside examination, patient/family counseling on new heart failure regimen, and discharge summary documentation.” Coding: 99239. Rationale: Time exceeds 30 minutes and is explicitly documented. All activities are discharge-related and personally performed by the physician.
Patient: 68-year-old being discharged to inpatient rehabilitation after ischemic stroke with residual right-sided weakness. Activities: Final neurological examination (10 min), review of rehabilitation placement options and coordination with case management and the receiving rehabilitation facility (15 min), family meeting to discuss long-term expectations, driving restrictions, and return precautions (10 min), prescription for dual antiplatelet therapy and statin written, neurology follow-up referral completed (8 min). Total time: 43 minutes. Coding: 99239. Rationale: Complex neurological discharge requiring extensive care coordination and family counseling justifies time well exceeding 30 minutes. Family/caregiver instruction time counts toward total time.
Setup: Hospital medicine PA conducts the discharge examination, provides medication instructions, and completes the discharge summary (25 min). The supervising hospitalist then reviews the plan, reviews the note, adds clinical nuance to the medication reconciliation, and personally counsels the patient on a new anticoagulant (15 min). Total combined time: 40 minutes; Physician time: 15 min; PA time: 25 min. Substantive portion: The PA spent more than 50% of the total time. The PA is the billing provider at the NPP rate. Coding: 99239 with Modifier FS (billed under PA’s NPI, physician’s NPI in referring field). Rationale: Under 2024–2026 split/shared rules, the PA performed the substantive portion by time. Modifier FS is required for Medicare. Documentation must record both providers’ individual time contributions.
Setup: Patient admitted for end-stage COPD exacerbation passes away on hospital day 4. The attending physician is called to the bedside to perform the pronouncement of death, counsel the family, complete the death certificate, and dictate a discharge summary. Total physician time: 45 minutes. Coding: 99239 (date of actual pronouncement). Rationale: Only the physician who personally performs the pronouncement may bill. The billing date reflects the calendar date of the pronouncement, even if paperwork is completed the following day. Time exceeds 30 minutes and should be documented explicitly.
Setup: Patient being discharged from inpatient stay for hip fracture repair and admitted to a skilled nursing facility on the same date. The attending physician spends 35 minutes on the hospital discharge (final examination, discharge summary, coordination with SNF staff) and then bills a separate SNF admission code. Coding: 99239 (hospital discharge) + SNF initial care code (e.g., 99306), same date of service. Rationale: CMS explicitly allows both the hospital discharge code and a nursing facility admission code on the same date when billed by the same physician. These are distinct, separately payable services.
Per FCSO Medicare and CMS Recovery Audit data, the following are the most frequently cited deficiencies in hospital discharge day management claims :
| Error Type | Description | Correction |
|---|---|---|
| No time documented | Physician bills 99239 with no time statement in the note at all. | Always include explicit total minutes in the discharge note. 99238 does not require a time statement; 99239 does. |
| Time of exactly “30 minutes” | Note says “30 minutes spent discharging patient.” This only satisfies 99238. | Document the actual time spent. If it exceeds 30 minutes, state “31 minutes,” “35 minutes,” or the exact figure. |
| Including staff time | Physician includes time spent by nurses providing discharge education or by case managers arranging post-acute care. | Count only personally performed physician (or NPP) time. Clinical staff time is not countable. |
| Carrying over time from prior day | Physician includes time spent on the patient the day before discharge in the discharge time total. | Only same-calendar-date activities count. Prior day’s work cannot be included in 99239 time. |
| Billing 99239 on same-day admit/discharge | Patient admitted and discharged on the same date; attending bills 99239 instead of 99234–99236. | For same-calendar-date admissions with 8+ hours in hospital, use 99234–99236. For under 8 hours, use 99221–99223 only. |
| Consultant billing 99239 | A subspecialist visits the patient on discharge day and bills 99239. | Only the attending/admitting physician of record bills discharge day management. Consultants bill subsequent hospital care (99231–99233). |
| No face-to-face encounter | Discharge managed remotely (by phone or through nursing); no in-person exam documented. | A face-to-face encounter is required for both 99238 and 99239. The discharge cannot be managed entirely without a bedside visit. |
| Billing 99239 + 99232 same day | Attending rounds in the morning and bills 99232, then performs the discharge later and adds 99239. | The discharge code covers all E/M by the attending on the discharge date. The subsequent visit code is bundled. Bill only 99239 for the day. |
