Internal medicine practices manage a wide range of services, from routine office visits and preventive care to chronic-condition management and diagnostic testing. That variety creates plenty of opportunities for claims to slow down or be denied.
The goal isn't simply to work denials faster after they happen. A stronger revenue cycle identifies the recurring causes of denials and addresses them before the claim is submitted.
Here are six areas internal medicine practices should watch closely.
1. Missing or expired prior authorization
Prior-authorization requirements vary considerably by payer, plan and service. A service that requires authorization for one patient may not require it for another, and requirements can change as coverage changes.
Problems commonly occur when an authorization was never obtained, does not cover the service ultimately performed, expires before the date of service, or does not match the payer information attached to the claim.
How to reduce the risk: Verify eligibility and authorization requirements before applicable services are performed. For services scheduled in advance, recheck authorization status when appropriate, particularly if the patient's coverage or scheduled date changes.
2. E/M coding that is not supported by the documentation
Evaluation and management services are central to most internal medicine practices.
For Medicare office and outpatient E/M visits, levels 2 through 5 are selected based on either the level of medical decision-making (MDM) or total time, when time is used for code selection. History and examination should be medically appropriate, but they are no longer counted as the elements that determine the office/outpatient E/M level.
Problems arise when the code submitted does not match what the record supports.
How to reduce the risk: Use current coding guidance and review higher-risk claims before submission. When an E/M level is based on MDM, the documentation should support the relevant problems addressed, data reviewed and analyzed, and risk. When time is used, the record should support the applicable total time.
3. Coordination of Benefits errors
Patients with more than one insurance plan create another common source of payment delays.
If payer order is incorrect, coverage information is stale, or required information from the primary payer is missing when a secondary claim is submitted, the claim may be rejected or denied.
How to reduce the risk: Verify active insurance and coordination-of-benefits information regularly and confirm the correct payer sequence before billing.
4. Missed timely-filing deadlines
Timely-filing limits vary by payer and contract. A valid claim can still become uncollectible if it is not submitted, corrected or appealed within the applicable deadline.
This is particularly important when a claim has already passed through multiple rounds of edits, requests for information or payer responses.
How to reduce the risk: Track unresolved claims by payer and age, maintain payer-specific filing requirements, and escalate claims well before they approach a filing or appeal deadline.
5. Documentation problems with specialized services
Internal medicine encompasses services with very different documentation requirements. Chronic care management, annual wellness visits and incident-to services, for example, should not be treated as though they share a single documentation checklist.
Each service must meet the requirements applicable to that service, payer and billing situation.
How to reduce the risk: Use service-specific workflows and documentation checks rather than a generic template for every encounter. Review requirements whenever coding rules, payer policies or service offerings change.
6. Incorrect or unsupported modifiers
Modifiers communicate important information about how or why a service was performed. Used correctly, they help a payer adjudicate the claim properly. Used incorrectly, they can cause denials, payment errors or additional review.
How to reduce the risk: Apply modifiers only when supported by the service and documentation, and include modifier review in pre-bill claim validation for services where modifier use is common.
Prevention is only half of denial management
Even a strong front-end process will not eliminate every denial. Payer edits change, patient coverage changes, documentation can be incomplete and claims sometimes require additional information or appeal.
The stronger approach connects prevention, claim tracking and denial resolution. Practices should be able to see which denial categories are increasing, which payers are responsible, how much A/R is aging and whether the same problems keep recurring.
Ascentiant Health provides full-cycle and supplemental revenue cycle support that includes medical billing, eligibility verification, prior authorization, denial management and appeals, payment posting and A/R recovery. Its Revenue Cycle Operations Platform provides claims, denial and aging visibility so revenue-cycle issues can be identified and worked systematically.
Reduce preventable denials and recover the claims that still require follow-up.
