TCM Billing: CPT 99495 vs 99496 Requirements, Timelines and Documentation

By Jay Chowdappa, MD, co-founder and CEO, Zynix AI · Updated October 30, 2026

Key takeaways

CPT 99495 and 99496 both pay for 30 days of transitional care management (TCM) after a qualifying discharge, and both require an interactive contact within 2 business days. 99495 needs at least moderate medical decision making and a face-to-face visit within 14 calendar days; 99496 needs high medical decision making and a visit within 7 calendar days.

• The 30-day TCM period starts on the day of discharge and runs for the next 29 days.
• Medication reconciliation and management must be done no later than the date of the face-to-face visit.
• Only one practitioner may report TCM, once per patient in the period; the date of service is the face-to-face visit date.
• Document at least the discharge date, the first interactive contact date, the face-to-face visit date and the level of medical decision making.

99495 vs 99496 at a glance

The two codes share the same service period and contact rule. They differ in medical decision making and in how soon the face-to-face visit must happen.

If a patient needs high complexity decision making but the visit happens on day 10, 99496 is not met. Report 99495, which requires at least moderate decision making and a visit within 14 days.

Which discharges qualify for TCM?

TCM applies when a patient is discharged from an inpatient or partial hospitalization setting and returns to a community setting. CMS lists these discharge settings:

• Inpatient acute care hospital, inpatient psychiatric hospital, inpatient rehabilitation facility and long-term care hospital
• Skilled nursing facility
• Hospital outpatient observation or partial hospitalization
• Partial hospitalization at a community mental health center

The community setting the patient returns to can be their home, a domiciliary such as a group home or boarding house, a nursing facility or an assisted living facility.

What counts as the 2-business-day interactive contact?

The interactive contact is a phone call, email or face-to-face exchange with the patient or caregiver, made by the practitioner or by clinical staff under their direction within 2 business days after discharge. The person making it must be able to address the patient's status and needs beyond scheduling follow-up care.

• Counting business days. In CMS's TCM FAQ example, a patient discharged on Monday afternoon must be contacted by the end of Wednesday, the second business day after the day of discharge.
• Unsuccessful attempts. If two or more separate, timely attempts are made and documented but do not reach the patient, TCM may still be reported when every other requirement, including a timely face-to-face visit, is met. CMS expects attempts to continue until they succeed.
• Who makes it. Clinical staff are people supervised by a physician or other qualified health care professional and allowed by law, regulation and facility policy to perform or assist in the service.

How do you choose between 99495 and 99496?

Choose by the level of medical decision making across the 30-day period and by when the face-to-face visit actually happened. CMS defines the levels by the 2023 CPT E/M guidelines, using three elements:

• Problems: the number and complexity of problems addressed.
• Data: the amount and complexity of records, tests and other information reviewed and analyzed.
• Risk: the risk of complications, morbidity or mortality of patient management.

High decision making plus a visit within 7 days supports 99496. Moderate decision making, or a visit on days 8 to 14, points to 99495. A visit after day 14 means TCM cannot be billed.

What non-face-to-face services are part of TCM?

Within the 30 days, the practitioner and clinical staff must provide the medically reasonable and necessary non-face-to-face services. CMS splits them by who does the work.

TCM billing rules and common denials

Most TCM denials trace back to timing, duplicate billing or overlapping periods. The rules to check before every claim:

• Only one physician or non-physician practitioner may report TCM, and only once per patient during the TCM period.
• The same practitioner may report discharge day management and TCM, but the required face-to-face visit cannot be on the same day as discharge day management.
• TCM is not paid if any part of the 30-day period falls within a global surgery period for a procedure billed by the same practitioner.
• Other medically necessary E/M visits after the required face-to-face visit can be billed separately.
• Report the face-to-face visit date as the date of service. You may submit the claim once that visit is done instead of holding it to day 30.
• Both codes may be furnished by telehealth.
• Physicians of any specialty, nurse practitioners, physician assistants, clinical nurse specialists and certified nurse-midwives can provide TCM.

Several care management services can be billed in the same period when time and effort are not counted twice. CMS's current booklets list chronic care management (CCM) codes 99487, 99489, 99490 and 99491 among them, along with remote physiologic and therapeutic monitoring, certain ESRD services, INR monitoring, home health and hospice supervision (G0181 and G0182) and prolonged services without direct patient contact. The practitioner who bills APCM for the patient that month cannot also bill TCM for that patient.

If the patient is readmitted within the 30 days, CMS's FAQ says TCM can still be reported for the first discharge as long as the services are furnished in the period, including after the second discharge. Alternatively, the practitioner can bill TCM for a full 30 days after the second discharge if no other provider bills it for the first. TCM may not be reported again by the same individual or group for a later discharge within 30 days.

What should a TCM program document?

At a minimum, CMS expects the medical record to show four things:

1. The patient's discharge date
2. The date of the first interactive contact with the patient or caregiver (or the dated, unsuccessful attempts)
3. The face-to-face visit date
4. The level of medical decision making, moderate or high

Add the medication reconciliation date, since it must fall on or before the visit, and the non-face-to-face services provided. Those are the details an auditor looks for.

Where TCM programs break down

TCM usually fails on logistics, not clinical care: the practice learns about the discharge too late, the 2-business-day contact is missed, or the follow-up visit slips past day 7 or day 14. Programs that hold up start from ADT discharge notifications, assign each discharge to a named clinical staff member on day 0, and book the visit during the first contact.

Zynix AI's post-discharge TCM workflow for ACOs starts outreach from ADT alerts, books the follow-up visit with primary care and routes the patient to a nurse, who makes the TCM interactive contact. Licensed clinical staff own that contact and every clinical judgment; the agents handle reminders, scheduling and the calls your team scripts. Ready-made care plans for TCM, CCM and wellness visits close only when each step is documented.

Frequently asked questions

What is the difference between CPT 99495 and 99496?

Both codes cover 30 days of transitional care management after a qualifying discharge and require an interactive contact within 2 business days. 99495 requires at least moderate medical decision making and a face-to-face visit within 14 calendar days of discharge. 99496 requires high medical decision making and a face-to-face visit within 7 calendar days.

Can a nurse make the TCM interactive contact?

Yes. The contact can be made by the practitioner or by clinical staff under the practitioner's direction, such as a nurse, as long as that person can address the patient's status and needs beyond scheduling follow-up care. It can be by phone, email or face to face, within 2 business days after discharge.

What if the patient cannot be reached within 2 business days?

CMS allows TCM to be reported if two or more separate attempts were made in a timely manner and documented in the medical record, and every other requirement is met, including a face-to-face visit within 7 or 14 days. Keep trying until you reach the patient; without a timely visit, TCM cannot be billed.

When can a TCM claim be submitted?

CMS's TCM FAQ says the date of service is the date of the required face-to-face visit, and the claim may be submitted once that visit is furnished. You do not have to hold the claim until the 30-day period ends. Only one practitioner can report TCM for the patient in that period.

Can the TCM face-to-face visit be done by telehealth?

Yes. CMS lists CPT 99495 and 99496 among the services that can be furnished through telehealth. The visit must still happen within the 7 or 14 calendar days the code requires, and it is part of the TCM service, so it is not billed separately.
