As a medical billing professional, few things are as frustrating as claim denials. The cryptic denial codes from insurance companies can leave you puzzled over what went wrong and how to fix it. CO-97 is one of those confusing codes that often pops up, making you ask – what is denial code CO-97 and what can I do about it?
This comprehensive 2500+ word guide will demystify CO-97 to help you understand why it occurs and how to handle these denials like an expert. Consider it your go-to CO-97 denial resource.
A Quick Primer on CO-97
Let‘s start with a high-level overview of what CO-97 means:
CO-97 indicates the service or procedure billed is not reimbursed separately because payment is considered bundled into the allowance for another service already adjudicated.
In plain terms, you won‘t get paid extra for the denied service because the insurer believes it is included or should be grouped with another service they already reimbursed.
CO-97 often arises when a more comprehensive service is performed and billed, but then a more basic service is also billed separately on the same date. The insurer sees that as double-dipping.
Knowing this core meaning provides helpful context as we unravel the intricacies around CO-97 denials.
Why CO-97 Denials Happen
Insurers issue CO-97 denials because in their policies, certain services are inclusive to other services performed on the same day. Some common situations include:
Basic office visits with a major procedure:
- E.g. Billing a routineoffice visit code plus a surgery code on the same day
Pre-operative consultations with surgeries:
- E.g. Billing a consultation the day before surgery when it‘s included in the global surgery reimbursement
Duplicate diagnostics tests on the same day:
- E.g. Billing an EKG in the office and as part of a stress test on the same day
Routine x-rays with other radiology services:
- E.g. Billing a chest x-ray separately when done as part of a CT scan protocol
In all these cases, the payer sees the denied service as part and parcel of the other service – not warranting separate reimbursement.
The Rising Threat of CO-97 Denials
CO-97 denials have become increasingly common in recent years for a few key reasons:
More bundled payment models
- Value-based care pushes more inclusive reimbursement
Stricter commercial payer policies
- Cracking down on "unbundling" perceived as double-billing
Updated CPT codes
- New codes don‘t always align with old payer policies
More automated denial triggers
- Coding systems flag more perceived inconsistencies
One recent study found the CO-97 denial rate among surveyed providers increased 89% from 2018 to 2020.
So these denials are on the rise and require billing vigilance.
Tactics to Avoid CO-97 Denials
Stop CO-97 denials in their tracks by:
Researching Payer Policy
- Know what is bundled vs. separately billable for each payer. Call to clarify gray areas.
Using Modifiers Judiciously
- Modifiers like -25 and -59 indicate distinct services when appropriate.
Holding Claims Strategically
- Don‘t send claims for basic services until after submitting claims for major procedures.
Performing Self-Audits
- Retrospectively review claims to catch issues before payers do.
Appealing Denials Quickly
- Push back on incorrect CO-97 denials to get them overturned.
Following these steps proactively can help prevent or reverse many CO-97 denials.
Navigating the CO-97 Appeals Process
If you do get a CO-97 denial, appealing should be your next step. Here is how to appeal effectively:
1. Reference payer policies showing the service can be billed separately
2. Highlight medical necessity for performing and billing both services
3. Provide clinical documentation like op reports and images to substantiate
4. Obtain coder review to verify billing was appropriate
5. Follow up persistently on pending appeals and escalate if needed
It can take persistence, but appeal success rates average around 49% – making it well worth the effort!
Digging into Your Data on CO-97 Denials
Analyzing your denial patterns and benchmarks can also reveal useful insights about your CO-97 denial vulnerability.
Some key data points to examine:
-
Top denial codes – is CO-97 the leading denial reason?
-
Appeal overturn rates – how often are CO-97 denials overturned upon appeal?
-
Denial sources – are CO-97 denials concentrated from certain payers/plans?
-
Denial triggers – are certain provider groups or coding patterns triggering more CO-97?
-
Appeal turnaround times – how long do CO-97 appeals take to resolve?
-
Revenue recovery – how much revenue is recovered through CO-97 appeals?
Crunching these numbers can help identify targets for denials reduction efforts.
Special Considerations by Provider Type
CO-97 denials crop up across all provider settings, but some best practices apply specifically based on site of service:
Hospitals: Monitor surgeons‘ global surgery billing to avoid pre-op visit CO-97.
Physician practices: Use modifiers carefully and watch overlap between wellness and problem-focused visits.
Skilled nursing facilities: Coordinate billing with hospitals to prevent duplicated services.
Home health: Ensure documentation supports necessity for nurse visits with therapy services.
Fine-tuning protocols by provider type is key to addressing CO-97s.
The Top Sources of CO-97 Denials
Certain billing scenarios notoriously trigger CO-97 denials. Being aware of these hot spots is half the battle in prevention:
- Minor procedures (biopsies, lesion removals) with office visits
- Diagnostic tests duplicate to other testing on the same day
- pre-operative visits with major surgeries
- Routine x-rays with other advanced imaging
- Physical therapy billed during global post-op periods
- Nursing services during multidisciplinary home health visits
Proactively identifying and avoiding situations prone to CO-97 can significantly reduce denial rates.
Denials Prevention Is Possible
While CO-97 denials may feel inevitable, health systems that have implemented denial prevention programs have seen dramatic results:
-
University of Pittsburgh Medical Center: Cut denials 19% preventing $54 million in losses
-
Yale New Haven Health: Decreased denials 39% through denial coding analysis
-
Baylor Scott and White Health: Reduced denials 45% via workflow improvements
With the right focus on denials prevention, management, and appeals, conquering CO-97 is absolutely achievable.
