Billing tips
Document the 15-minute typical time only if using time-based billing; for 2021+ E/M changes, MDM level determines code selection
Impact: Incorrect time documentation can trigger downcoding from $47.55 to lower-level codes or payer audits
Clearly document why the patient required a home visit rather than office visit (homebound status, mobility issues, safety concerns)
Impact: Missing medical necessity justification is the #1 denial reason; can result in 100% claim denial
Verify the patient is truly 'new' (no professional service from same specialty within past 3 years); otherwise use established patient codes 99347-99350
Impact: New vs established errors result in automatic denials; established codes pay differently ($47.55 for 99341 vs $38.36 for comparable 99347)
For straightforward MDM, document minimal number and complexity of problems (1 self-limited/minor), minimal data review, and minimal risk
Impact: Insufficient MDM documentation can lead to downcoding; upcoding to 99342 without proper MDM documentation risks audits and recoupment
Bill place of service code 12 (home) for private residence or appropriate facility code for assisted living/group home
Impact: Incorrect POS codes trigger automatic denials and can affect reimbursement rates; facility vs non-facility differentials apply
Consider chronic care management (CCM) codes as add-ons for patients with multiple chronic conditions requiring ongoing coordination
Impact: Can generate additional $42-$110/month in revenue per patient when appropriately documented and billed
Common denials
Medical necessity not established for home visit vs office visit
How to appeal: Submit appeal with documentation of homebound status, mobility limitations, safety concerns, or medical contraindications to office visit. Include physical therapy notes, durable medical equipment orders, or physician certification of homebound status if available.
Patient not considered 'new' - professional service within past 36 months from same specialty
How to appeal: Review billing records to confirm no face-to-face service in past 3 years. If confirmed as new, submit appeal with documentation showing date of last encounter was beyond 36-month window or was different specialty/tax ID. If truly established, rebill with appropriate 99347-99350 code.
Insufficient documentation to support straightforward MDM level
How to appeal: Submit complete medical record showing number and complexity of problems addressed, data reviewed/ordered, and risk level. Highlight elements meeting straightforward MDM criteria per 2021 E/M guidelines. If documentation insufficient, accept downcoding and improve future documentation.
Duplicate claim - same date of service billed by another provider or location
How to appeal: Clarify with modifier AI or documentation that services were separate and distinct. If services were split/shared, submit documentation showing which provider performed what portion and ensure split-shared visit rules are met.
