Three chronic leak points dominate primary care: annual wellness visits billed without the separately identifiable problem visit they actually included, chronic care management months that quietly miss their time thresholds, and transitional care management claims that fall outside the 7- or 14-day contact windows. Each has a specific, documented fix — and each runs on a time clock.
Start with wellness. Annual wellness visits (G0438 initial, G0439 subsequent) are preventive by construction, but clinicians routinely address problems during the same encounter — a medication change, an acute complaint, a chronic condition that worsened. When that happens, the problem-oriented E/M is billable in addition, with modifier 25 on the E/M and documentation showing a significant, separately identifiable service. Without the modifier, the claim either denies or leaves the visit value on the table. Without the documentation, the claim is indefensible.
Next, care management. Chronic Care Management codes pay monthly for documented care coordination: 99490 at 20+ minutes per calendar month, and the complex tiers (99487/99489) at 60+ minutes with the same monthly structure, plus principal care management alternatives. The leak is silent — months that never reached the threshold are simply unbillable, while sloppy time tracking makes billable months look risky to auditors. We maintain a per-patient time ledger so credits accrue as they happen, not from a month-end estimation.
Finally, transition windows. Transitional care management (99495 non-complex, 99496 complex) requires interactive patient contact within 2 business days and a face-to-face visit within 7 or 14 days of hospital discharge, depending on complexity. The payment is substantial precisely because the windows are strict — a claim filed on day 15 for a 99496 is denied, and the missed window cannot be recreated. Our discharge-tracking queue flags each patient's deadline the day the discharge hits the fax line.
