Yes \u2014 for most multi-provider OBGYN groups, claims sitting in accounts receivable past 120 days routinely contain six figures in recoverable OBGYN revenue, often tied to global maternity billing errors, IUD and Nexplanon supply codes, and timely filing gaps that never got worked before write-off.<\/p>\r\n

What Counts as “Legacy” AR in an OBGYN Practice<\/h2>\r\n

Legacy AR isn’t just old invoices. It’s the claim inventory your team has effectively stopped chasing \u2014 usually 120 days and older \u2014 where the assumption becomes “if it hasn’t paid by now, it won’t.”<\/p>\r\n

That assumption is expensive. In OBGYN specifically, legacy AR clusters around a few recurring mechanisms: global maternity packages (CPT 59400, 59510, 59610, 59618) split incorrectly across antepartum and delivery claims, supply codes for IUDs and Nexplanon (J7297, J7301, J7307) billed without matching NDC documentation, and postpartum visits denied for falling inside someone else’s global period.<\/p>\r\n

Where the Revenue Actually Hides<\/h2>\r\n

Three mechanisms account for most of the buried dollars we find during old AR recovery<\/a> engagements with OBGYN groups:<\/p>\r\n

Global maternity fragmentation.<\/strong> Antepartum visits billed separately from a delivery that later gets coded globally trigger automatic denials on the standalone visit claims \u2014 denials that sit unworked because staff assume the global code already covers them.<\/p>\r\n

Supply-code documentation gaps.<\/strong> IUD and Nexplanon insertions frequently pay for the procedure but deny the device itself when NDC numbers, lot numbers, or invoice cost don’t match payer requirements \u2014 a $700\u2013$1,200 loss per device, repeated hundreds of times a year in a busy practice.<\/p>\r\n

Credentialing lapses on new associates.<\/strong>\u00a0A new OBGYN or CNM seeing patients before payer enrollment\u00a0is finalized generates claims that are denied for “provider not recognized,” and those claims age out because front-desk staff doesn’t flag them as a\u00a0credentialing<\/a> issue rather than a coding issue<\/span>.<\/p>\r\n

Aging Bucket Recovery Reality<\/h2>\r\n

Most timely filing windows for commercial payers close within 90 to 180 days, and state Medicaid MCOs often have shorter windows. Once a claim crosses that line, recovery becomes structural, not just administrative \u2014 the fix isn’t rebilling, it’s finding why the claim sat untouched.<\/p>\r\n

The Triple Threat to OBGYN Legacy AR:<\/h2>\r\n
    \r\n
  1. Global Period Fragmentation<\/strong> \u2014 antepartum and postpartum visits denied against a global maternity code the front-end team never reconciled.<\/li>\r\n
  2. Supply Documentation Gaps<\/strong> \u2014 IUD and Nexplanon device costs denied for missing NDC data, quietly written off as “not billable.”<\/li>\r\n
  3. Credentialing Blind Spots<\/strong> \u2014 new provider claims aging past 120 days because no one connected the denial pattern to an enrollment delay.<\/li>\r\n<\/ol>\r\n

    How to Audit Legacy AR Before You Write It Off<\/h2>\r\n

    Before any claim over 120 days gets written off, run it through three checks: Is the claim denial<\/a> reason code documented, or just assumed? Is the timely filing deadline confirmed closed, or still open with the right payer? And was this claim ever actually appealed, or did it just age silently?<\/p>\r\n

    Practices that skip this step lose recoverable revenue not because the claim was unpayable, but because no one worked it in time.<\/p>\r\n

    Why the Right OBGYN Billing Partner Matters<\/h2>\r\n

    Legacy AR recovery isn’t a one-time cleanup \u2014 it’s a symptom of whether your OBGYN billing services<\/a> partner understands maternity bundling, supply-code documentation, and credentialing timelines well enough to prevent the backlog from forming again. A practice that treats denial management<\/a> as a downstream cleanup task, rather than a revenue cycle management<\/a> discipline built into daily workflow, will keep generating new legacy AR even after the old backlog is cleared.<\/p>\r\n

    MBC Spotlight<\/h2>\r\n

    MBC’s OBGYN Center of Excellence combines specialty-specific coding protocols with a dedicated account manager who reconciles global maternity claims, supply-code documentation, and credentialing status in a single workflow \u2014 many multi-provider OBGYN groups may have significant recoverable revenue in claims aged over 120 days, depending on payer mix, claim volume, and denial management practices. Practices searching for the best OBGYN billing company<\/a> consistently choose partners that combine depth in specialty coding with proactive AR management.<\/p>\r\n
