Critical Care Billing Services That Protect Every Minute You Spend at the Bedside
In critical care, you are paid for time. One missed minute threshold costs revenue. One documentation error triggers a denial. And a team still using outdated time thresholds is silently undercoding on every claim in the 75 to 103-minute range.
GenMediTech's critical care billing services are built for intensivists, pulmonologists, emergency physicians, and critical care groups who need a billing partner that understands the rules, not just the codes.

Why Critical Care Billing Is Unlike Any Other Specialty
Most specialties bill for procedures. Critical care bills for time. That one difference creates rules that most general billing teams are not equipped to handle.
Three things make it uniquely complex:
Time Based, Not Encounter Based
It is time based, not encounter based. The provider must document total minutes spent on critical care, not just that a visit happened.
Current Payer Specific Thresholds
Medicare and commercial payers must be billed using current thresholds. Teams using outdated time rules leave significant revenue behind on every affected claim.
Strict Bundling Rules
Bundling rules are strict. Several procedures are included in critical care reimbursement and cannot be billed separately. Others must be billed apart. Confusing the two costs money in both directions.
Critical Care Time Thresholds — What Most Billing Teams Get Wrong
This is the most commonly miscoded area in critical care billing. Getting it wrong leads to undercoding, lost revenue, or compliance risk.
Current Time Thresholds for Medicare and Commercial Payers
CMS has fully aligned its critical care time thresholds with CPT guidelines. Both Medicare and commercial payers now follow the same rules.
| Time Spent | CPT Commercial Payers | Medicare CMS |
|---|---|---|
| Less than 30 minutes | Do not bill 99291 | Do not bill 99291 |
| 30 to 74 minutes | Bill 99291 only | Bill 99291 only |
| 75 to 103 minutes | Bill 99291 plus 99292 | Bill 99291 plus 99292 |
| 104 to 133 minutes | Bill 99291 plus 99292 x1 | Bill 99291 plus 99292 x1 |
| 134 to 163 minutes | Bill 99291 plus 99292 x2 | Bill 99291 plus 99292 x2 |
What Counts as Critical Care Time
- Direct patient care at the bedside
- Reviewing test results, imaging, and monitoring data near the patient
- Discussing care and treatment decisions with family or decision makers
- Documenting the critical care record
- Interpreting blood gases, cardiac output, or ventilator data as part of active management
What Is Excluded from Critical Care Time
- Teaching residents or medical students
- Administrative and clerical tasks
- Time spent on procedures billed separately
- Time with patients who do not meet the clinical definition of critical care
Common Critical Care Billing Challenges We Solve
Using outdated time thresholds and undercoding claims in the 75 to 103-minute range
Including separately billable procedure time inside the critical care total
Missing the daily aggregation rule for non-continuous critical care
Documentation stating "approximately 90 minutes" instead of exact time, which payers reject on audit
Split-shared visits between physicians and NPPs coded without modifier FS
Pediatric and neonatal critical care codes billed under adult critical care rules
Denial follow-up not happening fast enough on high-value claims
Our Critical Care Billing Services
Accurate Critical Care Coding
Our coders understand time-based billing and apply current payer specific thresholds to every claim. We handle:
- Adult critical care (99291 and 99292) for ICU, CCU, MICU, SICU, and PICU settings
- Neonatal critical care (99468 and 99469) for initial and subsequent days
- Pediatric critical care (99471, 99472, 99475, 99476) for initial and subsequent days
- Emergency department critical care services
Documentation Gap Identification
We flag documentation that does not support the billed code before claims go out. Vague time statements, missing exclusion language for separately billed procedures, and incomplete clinical justification are caught before submission, not after denial.
Eligibility Verification and Prior Authorization
Every patient gets a real-time eligibility check before the claim is built. Missing or expired authorizations get flagged before they become denials.
Clean Claim Submission
Our system applies payer specific rules separately for each payer. No manual workarounds. No cross-applying the wrong logic to the wrong plan.
AI Powered Denial Management
GenMediTech's AI Denials Management platform tracks denial patterns across all critical care claims by denial code, payer, provider, and time range. When a pattern appears, we fix the upstream cause, not just the individual claim.
Denial Appeals
Critical care appeals succeed at a 40 to 60 percent rate when documentation supports the claim. Our team pursues every appropriate denial with correct supporting documentation, payer policy citations, and time logs, not generic appeal letters.
Payment Posting and Underpayment Review
Every payment gets checked against contracted rates. Critical care reimbursement is too high per claim to allow underpayments to pass through silently.
Credentialing and Enrollment
We manage credentialing to prevent revenue gaps caused by delayed payer enrollment for new intensivists or hospitalists joining a group.
Monthly Reporting
Reports show critical care collection rates, denial rates by reason code, time-range distribution of billed codes, and AR aging every month.

Frequently Asked Questions
Critical care billing is time-based coding and claim submission for physicians managing critically ill patients with organ failure or life-threatening instability. The primary codes are 99291 for the first period and 99292 for each additional 30-minute period.
Both Medicare and commercial payers now follow the same threshold. CPT 99292 can be billed starting at 75 minutes of total critical care time. Teams still applying the old 104-minute rule to Medicare patients are undercoding every claim in the 75 to 103-minute range.
99291 covers the initial critical care period from 30 to 74 minutes. 99292 is an add-on code for each additional 30-minute period. It can be billed starting at 75 cumulative minutes for both Medicare and commercial payers.
Yes. Multiple critical care encounters throughout the same day can be aggregated into a total time for coding. Each encounter must meet the critical care definition and must have exact time documented.
Pulse oximetry, basic vascular access, chest x-ray interpretation, ventilator management, gastric intubation, and temporary transcutaneous pacing are bundled into 99291 and 99292. Billing these separately triggers NCCI denials.
Endotracheal intubation (31500), central venous catheter placement (36555 and 36556), arterial catheterization (36620), chest tube insertion (32551), and CPR (92950) are separately billable. Time spent on these must be excluded from the critical care total.
No. Pediatric and neonatal critical care codes (99468 through 99476) are per-day codes, not time based. The 75-minute threshold applies only to 99291 and 99292.
No. When two physicians from the same group and specialty provide critical care to the same patient on the same day, only one 99291 can be billed per day.
When a physician and NPP from the same group both provide critical care on the same day, the provider who spends more than 50 percent of the total critical care time bills the service using modifier FS. CMS defines the substantive portion strictly by time for time-based services like critical care.
Specialty trained coders apply current time thresholds, prevent bundling errors, catch documentation gaps before submission, and follow up on denials with proper appeal documentation. Most critical care practices see measurable revenue improvement within the first billing cycle.
