CPT code 99349: Home visit for established patients

Key takeaways

CPT code 99349 covers a home or residence visit for an established patient. It requires a moderate level of medical decision making, or 40 minutes or more of total time on the encounter date.

The CPT descriptor sets a minimum time, not a time range. There is no stated upper bound. A visit stays at 99349 until the note supports high complexity MDM or reaches 60 minutes, which is the 99350 threshold.

Two pathways qualify a visit for the code. One is the MDM complexity level, the other is total time on the date of service. Only one of them has to be met.

Billing 99349 during an inpatient admission is an open CMS Recovery Audit Contractor (RAC) audit topic. Verify patient status before submission.

Practice management software like Pabau supports E/M home visit documentation, electronic claim submission, and internal coding audits.

CPT code 99349 is an evaluation and management (E/M) code for a home or residence visit with an established patient. The American Medical Association (AMA) publishes and maintains it within the 99341-99350 home visit series.

The code describes a visit requiring a moderate level of medical decision making (MDM). The alternative pathway is 40 minutes or more of total time on the encounter date. Place of service (POS) 12 applies in the patient’s private residence.

This is the second-highest of the four established patient home visit codes, sitting directly below CPT 99350. Providers reach for it when a chronic problem is exacerbating and the visit involves prescription drug management at moderate risk.

The 2023 descriptors give each code in the home visit series a single MDM level and a minimum time. There is no tier range and no bounded time window. Bounded ranges belong to the office visit codes 99202-99215, and they never appeared in the home visit descriptors.

When to use CPT code 99349: Billing criteria

Two pathways qualify a visit for 99349, and only one must be met. The 2023 AMA E/M revisions eliminated history and physical exam as selection criteria. Providers now choose either MDM complexity or total time.

Medical decision making requirements

MDM is assessed across three elements: problems addressed, data reviewed or analyzed, and risk of complications. The provider must meet or exceed the threshold in at least two of the three to qualify at a given level. For 99349, that means two of the three elements documented at moderate level.

The high column below is included for contrast. When two of the three elements reach high level, the correct code is 99350 rather than 99349.

Time-based billing: Total time requirements

When billing by time, 40 minutes must be met or exceeded on the date of service. The descriptor states a minimum only. It does not cap the code at 54 minutes or at any other figure. That cap is a misreading carried over from the office visit codes.

Total time is not limited to face-to-face contact. It counts four kinds of work done on the date of service:

• Preparing for the visit
• Reviewing records
• Documenting the note
• Coordinating care with other providers

Travel time to the patient’s home does not count toward the total.

The practical ceiling comes from the next code up rather than from the descriptor. Once total time reaches 60 minutes, the 99350 threshold is met and 99350 becomes the code that matches the work performed. Time between 40 and 59 minutes sits squarely at 99349, as the bands below show.

There is also no prolonged-service add-on at this level. CPT 99417, and HCPCS G0318 for Medicare, attach only to 99345 and 99350 in the home and residence series. A visit that runs long is reported by moving up to 99350, not by adding units to 99349.

Place of service billing rules for CPT code 99349

The 2023 revision merged the old domiciliary and rest home codes into this series, so 99349 now covers several residential settings. The POS code on the claim must match where the visit actually happened. Using POS 12 for an encounter in an assisted living facility is a coding error that will not survive a record request.

All four settings pay at non-facility rates, so a POS mix-up inside this group does not change the payment. It does change whether the claim accurately describes the site of service. Nursing facility settings are billed with the nursing facility E/M codes instead, not with 99349. Check the setting’s certification status before choosing the code family.

Documentation requirements for CPT 99349

Documentation must support whichever pathway the provider selects. A note that describes complex problems without documenting MDM elements explicitly, or that fails to record the time spent, leaves the claim undefended at audit. The 837P claim file used for electronic submission also needs the correct place of service and encounter date.

• Patient identification and demographics confirming established patient status
• Date of service and place of service (POS 12 for a private home; POS 13 for assisted living; POS 14 for a group home)
• Chief complaint and history relevant to the problems addressed
• MDM documentation: Problems addressed, data reviewed or ordered, and risk level. Time-based billing needs the total minutes instead.
• Assessment and plan with specific management decisions documented for each problem
• Provider signature with credentials and date
• HIPAA-compliant data handling for all patient information in the record

If billing by time, the note must state the total time spent and indicate that it includes non-face-to-face activities. Vague language like “time spent approximately one hour” does not satisfy this requirement. A clean claim depends on having that detail in the note before it leaves the practice.

Medicare reimbursement rates for CPT code 99349 (2026)

Home visits use non-facility rates under the CMS Physician Fee Schedule. The home qualifies as a non-facility setting (POS 12). The practice expense component of the relative value unit (RVU) therefore reflects higher costs than a facility setting.

The 2026 national average non-facility rate for CPT 99349 is approximately $130-$145. The exact figure depends on the CMS Physician Fee Schedule conversion factor in force for the year. Verify current rates in the CMS fee schedule lookup tool for your own MAC jurisdiction.

RVU breakdown for CPT code 99349

Multiplying the total RVU by the non-QP conversion factor gives roughly $132 before geographic adjustment. Practices in alternative payment models bill against the slightly higher qualifying participant factor.

Pabau submits claims electronically through Claim.MD, with real-time eligibility checks run before the visit. After Medicare adjudicates the claim, the practice receives an electronic remittance advice (ERA) file detailing the payment and any adjustments applied.

Geographic and commercial payer rate variation

Geographic Practice Cost Indices (GPCI) adjust the fee schedule rate by MAC jurisdiction. A practice in San Francisco will receive a meaningfully different payment than one in rural Mississippi for the same CPT 99349 claim. The difference can range 20-30% between high-cost and low-cost localities.

Commercial payers set their own rates, typically as a percentage of the Medicare fee schedule (often 100-130%). Check each payer contract individually. Applying your own locality’s GPCI values to the total RVU gives a closer estimate than the national average.

Common modifiers used with CPT code 99349

Modifiers are appended to the base code to signal special circumstances to the payer. Using the wrong modifier, or omitting a required one, is among the most common reasons E/M home visit claims are returned or denied. Practice management software like Pabau checks each modifier against the code first. Its medical claims management tools flag the conflict before the claim goes out, so your team fixes it once.

Modifier -AI has no valid use with 99349. It identifies the principal physician of record on initial hospital care, 99221-99223, and initial nursing facility care, 99304-99306. Neither range covers a home or residence visit.

ICD-10 codes commonly billed with CPT code 99349

The diagnosis submitted with 99349 must explain why the visit reached moderate complexity. Pick the condition that actually drove the decision making, not a background chronic problem sitting on the chart. A stable, well-controlled diagnosis paired with a moderate-level code invites a downcode request.

Who can bill CPT code 99349

Physicians and qualified non-physician practitioners can report 99349 under their own National Provider Identifier. That includes nurse practitioners, physician assistants, and clinical nurse specialists, subject to state scope of practice and payer credentialing.

Incident-to billing works differently in the home than in an office. Medicare requires direct supervision, which in a private residence means the physician is present in that residence during the service. A physician sitting in the office cannot supervise a home visit incident-to.

Split or shared visit rules also do not extend to this setting the way they do for facility-based E/M services. When a non-physician practitioner performs the visit alone, bill under that practitioner’s own NPI at the applicable payment percentage.

Related CPT codes in the home visit series (99341-99350)

The 99341-99350 home visit series covers both new and established patients across complexity levels. Selecting the correct code means matching the patient type to a single MDM level or to a minimum total time. Read the time column as a floor, never as a window.

CPT 99343 was deleted in the 2023 AMA revision. Do not bill it for dates of service on or after January 1, 2023, because claims using a deleted code will deny. There has never been a valid CPT 99346. A claim carrying that number rejects as an invalid code rather than as a deleted one.

Choosing between 99348, 99349, and 99350

Because each code carries one MDM level and one minimum time, the three established patient levels above straightforward sort cleanly. Work through MDM first, then check time as the alternative pathway.

• 99348 when the problems are stable and low level, or total time reaches 30 minutes but stays under 40.
• 99349 when a chronic problem is exacerbating or progressing at moderate risk, or total time reaches 40 minutes but stays under 60.
• 99350 when the visit involves severe exacerbation, intensive drug monitoring, or a decision about hospitalization, or total time reaches 60 minutes.

Pick whichever pathway the note supports best, then document that pathway explicitly. Recording both costs a line of text and removes the argument entirely.

How CPT code 99349 changed after the 2023 AMA revisions

The AMA restructured the home visit E/M series in 2023 to align it with the 2021 outpatient E/M overhaul. One code, 99343, was deleted from the new patient series, which dropped from five codes to four. The established patient series was untouched in count and still holds 99347 through 99350.

The remaining codes were redefined to use MDM complexity or total time as the sole selection criteria. That replaced the prior system built on history and physical exam. The AAPC CPT code lookup reflects the current post-revision descriptors for each code in the series.

The revision also folded the old domiciliary and rest home codes, 99334-99337, into this series. Practices that once split residential visits across two code families now report them all from 99341-99350.

Common billing mistakes and audit risks for CPT 99349

CMS Recovery Audit Contractors (RAC) maintain an approved audit topic specifically targeting home visit E/M codes. RAC Topic 0011 covers inappropriate billing of home visit professional service E/M codes during inpatient stays. That makes patient status the first thing to check on any 99349 claim.

Five errors account for the majority of denials and audit findings on CPT 99349 claims. Strong medical billing compliance processes catch these before submission rather than after a RAC letter arrives.

• Billing 99349 during an inpatient stay: CPT 99349 cannot be billed when the patient is admitted as an inpatient on the same date of service. CMS bundles home visit E/M services into the inpatient admission DRG. This is an active RAC audit topic. Verify patient status before billing. If the patient was admitted that day, the home visit E/M is not separately payable.
• Treating the time threshold as a range: Coders who learned the office visit codes often assume 99349 tops out around 54 minutes. It does not. A 57-minute visit still bills as 99349, and a 62-minute visit moves up to 99350 on the strength of that time alone.
• Insufficient MDM documentation: A diagnosis list alone does not validate the MDM. The note must describe the complexity of problems addressed, the data reviewed, and the risk level. Auditors look for explicit documentation of each MDM element, not just the problem list.
• Wrong place-of-service code: POS 11 (office) and POS 12 (home) are both non-facility settings, so the payment rate itself does not change. The problem is that POS 11 contradicts the home or residence setting this code requires. That mismatch undermines medical necessity and can prompt a recoupment request on review. Verify the POS code matches the actual site of service.
• Upcoding to 99349 from 99347 or 99348: This is the most common audit trigger for the code. It happens when MDM supports only straightforward or low complexity and no time documentation backs the 40-minute threshold. The note must demonstrably support the selected level.

How practice management software simplifies CPT code 99349 billing

Home visit billing has more moving parts than office-based E/M coding. Clinicians travel between addresses, time tracking is manual, MDM detail gets written away from a desk, and claims often sit for days before submission. Each of those steps is where a 99349 error starts.

The usual patch is a paper time log plus recall, with the note reconstructed in the evening. That reconstruction is what an auditor picks apart, because the time attestation was never captured at the point of care.

Pabau tightens three of those steps. Structured treatment note templates prompt the clinician to record problems addressed, data reviewed, and risk level. The moderate MDM pathway is then documented rather than implied.

Time can be logged in the chart during the visit, which turns the 40-minute threshold into a recorded fact instead of an estimate. Claim submission through Claim.MD then moves the charge out the same day, with eligibility already verified.

The outcome is a chart that defends the code it billed. When a RAC letter or payer record request arrives, the MDM elements and the time attestation are already in the note. Your team spends minutes on the response rather than days.

Conclusion

CPT 99349 carries one MDM level and one time floor. Moderate MDM qualifies, and so does 40 minutes or more. Reading it as a range is how practices underbill a long visit, or defend a level the note never supported.

Practices that bill home visits regularly get the most protection from capturing MDM and time at the point of care. A note reconstructed from memory hours later is far weaker.
