What dermatology billing looks like in Chicago
The defining billing problem in Illinois is retroactive eligibility. Medicaid members move between managed-care organizations, and the change is often applied backward, which means a claim that paid correctly is recouped months later because the member was assigned to a different plan on the date of service. Practices see this as random takebacks; it is a systematic pattern that can be worked.
The commercial market is concentrated, with a dominant Blues plan whose edits on excision sizing and same-day evaluation and management differ from the Medicare rules, so a single coding standard across all payers guarantees denials on one side or the other.
Large integrated health systems in the metro also impose referral chains that must be intact before a dermatology visit is billable.

Illinois rules that change how your claims are filed
Coverage policy, filing windows and payment deadlines are set at state and contractor level. These are the Illinois specifics we bill against. Payer policy changes, so confirm the current version before citing one in an appeal.
- Medicare coverage policy
- National Government Services Jurisdiction 6 covers Illinois, applying the same coverage-article family as New York — an advantage for multi-state groups standardising surgical documentation.
- Medicaid program
- Illinois HealthChoice through Meridian, Blue Cross Community Health Plans, Aetna Better Health, Molina and CountyCare in Cook County.
- Timely filing
- Medicare: 12 months. Illinois Medicaid: 180 days from date of service. Commercial: commonly 90 to 180 days.
- Prompt-pay statute
- 215 ILCS 5/368a requires payment of a clean claim within 30 days of receipt of electronic submission, with interest at 9% per year on late payment.
Denials we see most in Chicago
- Recoupments on paid claims after retroactive Medicaid plan reassignment.
- Rebills filed to the correct MCO after the filing window had already closed.
- Referral-missing denials on HMO products.
- Excision denials where the payer's sizing rules differ from Medicare's.
The controls we run against them
- Monthly retroactive eligibility sweep that identifies reassignments and rebills to the correct plan inside the filing window.
- Takeback tracking so recoupments are matched to a rebill rather than absorbed as a loss.
- Referral and authorization linkage validated before the encounter is billed.
- Payer-specific excision and evaluation and management rules maintained separately from the Medicare set.

Frequently asked questions
Why is Illinois Medicaid recouping claims that already paid?
Managed-care plan assignment is frequently applied retroactively, so the plan that paid was not the plan responsible on the date of service. The recovery path is a timely rebill to the correct plan, which is why the monthly retroactive sweep matters.
Can recouped claims still be collected?
Often yes, if the rebill reaches the correct plan inside its filing window. That is a matter of catching the reassignment quickly rather than at year end.
Do you handle HMO referral requirements?
Yes. Referral and authorization are verified and linked to the encounter before the claim is created.
