🎯 Quick Answer: What Happens to Collections After Outsourcing RCM?
In a well-run transition, collections may dip slightly in Month 1 because of payment timing, recover by Month 2, and rise above baseline from Month 3 as cleaner claims, denial work and old-AR recovery take effect:
| Month | What to Expect in Collections |
|---|---|
| Month 1 | Flat to slightly lower — new claims in transit |
| Month 2 | Back to baseline as clean claims pay |
| Month 3 | Above baseline; 90-day review |
| Month 4 | Underpayment recovery adds cash |
| Month 5 | Patient collections improve |
| Month 6 | New, higher run-rate established |
MDeRCM covers the riskiest part of the curve with 90 days of service and no invoice — see our zero-risk transition offer.
📉📈 1. The RCM Transition Curve: Why Cash Can Dip Before It Rises
When you outsource revenue cycle management (RCM), your services and charges do not change on Day 1 — but the people, systems and sometimes the clearinghouse do. Insurance payments arrive weeks after a claim is submitted (Medicare, for example, generally pays clean electronic claims no sooner than 14 days after receipt). So cash in the first month mostly reflects claims sent before the switch, while the benefit of cleaner new claims lands in Month 2 and later.
That timing creates a shallow “J-curve”: a possible small dip, then a climb above your old baseline. The depth of the dip depends almost entirely on preparation. The three things that flatten it:
Enroll ERA/EFT early
So payments keep posting electronically from day one.

Month 0: Before go-live (2–4 weeks)
💵 Collections: No change yet — your current process keeps running.
What happens this month
- Baseline KPIs captured: collections, days in AR, denial rate, AR over 90
- EHR/practice-management access and clearinghouse set up
- ERA/EFT enrollment updated where needed
- Credentialing and payer enrollment checked for every provider
- Agreement on who works old AR
👀 Watch: Missing ERA enrollments and provider enrollment gaps are the top causes of a deeper Month 1 dip.

| Month | Focus | Collections |
|---|---|---|
| Month 0 | Before go-live (2–4 weeks) | No change yet — your current process keeps running. |
| Month 1 | Go-live & stabilize | Flat to slightly lower. New claims are cleaner, but their payments are still in transit. |
| Month 2 | Cash catches up | Back to baseline or above as payments for clean Month 1 claims arrive. |
| Month 3 | Steady state | Usually above baseline; the 90-day review compares results to your starting numbers. |
| Month 4 | Optimize | Gains continue from underpayment recovery and fewer write-offs. |
| Month 5 | Patient & payer fine-tuning | Stable, higher run-rate; patient collections improve. |
| Month 6 | Maturity & review | New run-rate established; compare six months against baseline. |
📊 4. KPI Trajectory: What Should Improve, and When
Use this as a scorecard for your RCM partner. Front-end numbers move first; cash numbers follow.
| KPI | Typical Starting Point | By Month 1 | By Month 3 | By Month 6 |
|---|---|---|---|---|
| Clean claim rate | 80–90% | 92%+ | 95%+ | 97%+ |
| Clearinghouse rejections | Fixed weekly | Fixed in 24–48 h | Rare | Rare |
| Charge lag | 5+ days | Under 3 days | Under 2 days | Under 2 days |
| Denial rate | 10–15% | Starting to fall | Under 8% | Under 5% |
| Days in AR | 45–60 | May rise briefly | Falling | Under 35 |
| AR over 90 days | 20–30% | Being worked | Clearly lower | Under 15% |
| Net collection rate | 85–92% | Not yet meaningful | Improving | 95%+ |

🗂️ 6. What Happens to Your Old AR During the Switch
Old AR is where most transitions lose money. Pick one of these models — in writing, with dates:
| Model | How It Works | Pros | Risks |
|---|---|---|---|
| Previous vendor runs out old AR | Old vendor keeps working claims it submitted, usually 60–120 days | Continuity on old claims | Low motivation; claims can go quiet |
| New partner takes all AR | New team works everything from go-live | One owner, one dashboard | Needs full history and access on Day 1 |
| Split by age or payer | New team takes AR over a set age or for certain payers | Fresh eyes on the hardest claims | Gaps if the split is unclear |
Whatever model you choose, list every open claim, its filing and appeal deadline, and its owner. Learn more in the hidden cost of switching medical billing companies and use our 30-day AR cleanup checklist. MDeRCM’s AI AR management ranks legacy claims by deadline and value from the first day.
⚠️ 7. What Causes a Bigger Dip — and How to Avoid It
| Cause | Effect on Cash | Prevention |
|---|---|---|
| ERA/EFT not re-enrolled | Payments arrive on paper or unmatched; posting slows | Enroll before go-live — see ERA reconciliation |
| Provider enrollment gaps | Claims deny for credentialing | Verify every provider, NPI and location before Day 1 |
| Clearinghouse rejections | Claims never reach the payer | Test a sample batch; fix rejections daily |
| Charge lag | Claims go out late; cash slips a month | Agree a charge-entry deadline with providers |
| Old AR left unworked | Timely filing losses | Written AR plan with owners and dates |
| Missing payer contracts | Underpayments go unnoticed | Share contracts; enable contract variance checks |
| Eligibility not checked | Denials for terminated or changed coverage | Policy status verification before visits |
| Authorizations not transferred | Prior-auth denials on ongoing care | Hand over the auth log — see AI prior authorization |

📅 11. Outsourcing Near Year End: Timing Tips
Many practices decide to switch in the fall. That can work well — if you plan around three seasonal effects:
- Start in November if you can, so Month 1 is behind you before holiday payer slowdowns in late December.
- January brings deductible resets and plan changes (including Medicare Advantage switches), so patient balances and eligibility denials rise everywhere in Q1 — compare Q1 results to the prior Q1, not to December.
- Use the transition to clean up 2026 AR before deductibles reset.
See our year-end AR cleanup guide and self-pay optimization for January.
💲 12. What You Pay During the Transition
Most RCM companies charge a percentage of collections, so their fee rises and falls with your cash — which aligns them with a fast recovery. Watch for setup fees, minimum monthly fees, or separate charges for working old AR, which can make the first months expensive.
| Fee Type | Why It Matters in Months 1–6 |
|---|---|
| Setup / onboarding fee | Paid before any results |
| Monthly minimum | You pay even if Month 1 dips |
| Legacy AR fee | Higher % on old claims — check the rate |
| Add-ons (credentialing, appeals, statements) | Can double the effective rate |
| MDeRCM | 90 days with no invoice, then 4–7% all-inclusive; no setup fee, no lock-in |
