Billing tips
Document the specific elements supporting moderate MDM: prescription drug management, review of test results, assessment of exacerbation or progression of chronic illness, or independent historian required
Impact: Proper MDM documentation is the primary factor in audit defense; inadequate documentation can result in downcoding to 99348 ($94.18), a loss of $28.41 per encounter
Record total time spent on date of encounter if counseling/coordination exceeds 50% of visit time, including time before and after direct face-to-face contact
Impact: Time-based billing alternative allows 99349 billing when MDM is harder to document; 40-54 minutes total qualifies for 99349
Verify patient homebound status and medical necessity for home visit in documentation; explain why office visit was not appropriate
Impact: Home visit codes face scrutiny for medical necessity; lack of justification can trigger 100% denial and potential fraud investigation
Use place of service code 12 (home) for private residence or appropriate assisted living POS codes (13, 14) to ensure proper payment
Impact: Incorrect POS code can result in claim rejection or payment at wrong rate; automated edits may deny home visit codes with office POS
Bill higher complexity 99350 when MDM reaches high level (3.79 RVU vs 4.47 RVU difference of $22.03) or consider lower 99348 if only straightforward MDM documented
Impact: Accurate code selection prevents both undercoding (average $22-28 loss) and overcoding audit exposure
For Medicare patients, ensure visit frequency aligns with care plan; excessive home visit frequency triggers prepayment review
Impact: More than 2-3 home visits per month without clear medical necessity documentation may trigger targeted probe and educate reviews
Common denials
Medical necessity not established - payer states visit could have been conducted in office or via telehealth
How to appeal: Submit appeal with documentation of homebound status, mobility limitations, oxygen dependence, or other factors preventing office visit. Include physician attestation of medical necessity for in-person home assessment.
Insufficient documentation to support moderate level MDM - downcoded to 99348
How to appeal: Provide complete medical record showing at least moderate complexity: prescription drug management, review and interpretation of tests, assessment of acute complicated injury/illness, or multiple chronic conditions requiring coordination. Highlight specific elements meeting 2021 E&M guidelines.
Frequency limitation - too many home visits in short time period without different diagnosis or clear change in condition
How to appeal: Submit clinical notes demonstrating distinct medical reasons for each visit, changes in patient status, new symptoms, or acute exacerbations. Include care plan showing why frequent monitoring was medically necessary for this specific patient.
Incorrect place of service code or non-covered location (e.g., independent living billed as home)
How to appeal: Verify actual patient residence type and confirm appropriate POS code. If POS was correct, provide lease agreement or facility documentation confirming residence status. Correct and resubmit if POS was genuinely incorrect.

Can CPT 99349 be billed for assisted living facility visits?
Yes, CPT 99349 can be used for established patients in assisted living facilities, but only if the facility does not meet the definition of a nursing facility. Use place of service code 13 (assisted living) rather than code 12 (home). If the facility provides nursing facility level services, use domiciliary care codes 99334-99337 instead.
How often can you bill 99349 for the same patient?
There is no specific Medicare frequency limitation for 99349, but medical necessity must be documented for each visit. Frequent home visits (more than 2-3 per month) may trigger review unless clearly justified by patient condition changes, acute exacerbations, or complex care needs requiring ongoing monitoring.
What level of medical decision-making is required for 99349?
CPT 99349 requires moderate level medical decision-making under the 2021 E&M guidelines. This includes managing multiple problems with moderate severity, reviewing and interpreting external notes/tests, or prescription drug management. At least two of three MDM elements (problems, data, risk) must meet moderate level.
Can nurse practitioners bill CPT 99349?
Yes, nurse practitioners and physician assistants can bill CPT 99349 when performing home visits within their scope of practice. Medicare pays NPs at 85% of the physician fee schedule rate ($104.20 for 99349 in 2025) when billing under their own NPI. Incident-to billing at 100% requires physician availability but is difficult to meet in home settings.
