Critical care is paid by the minute, and Medicare and CPT count those minutes differently. Medicare pays 99292 only after a full 104 minutes of critical care, while CPT allows it from 75 minutes. Qualigenix codes intensivist claims to the documented time, takes separately billed procedure time out of the total, and bills each procedure that isn't bundled into 99291.
Intensivist billing depends on documented critical care time (99291 for the first 30–74 minutes, 99292 for each additional 30), knowing which ICU procedures are bundled into critical care and which are billed separately, and following Medicare's rules for split/shared visits, same-day E/M, and multiple intensivists on one patient. Qualigenix's coders bill intensivist groups and ICU teams with a 98.2% first-pass clean claim rate on first submission. Start with a free billing audit at 786-259-0231.
Critical care codes apply only when the patient has a critical illness or injury and the clinician gives high-complexity care to prevent life-threatening deterioration. Being in the ICU doesn't qualify a visit on its own. Under 30 minutes of qualifying time, the visit is billed as an inpatient E/M service instead.
Code 99291 covers the first 30–74 minutes. Medicare pays one unit of 99292 only after 104 total minutes, a full 30 minutes beyond 74. CPT guidance supports 99292 starting at 75 minutes, so commercial and Medicare claims for the same visit can need different units.
CPT bundles several services into critical care: interpretation of cardiac output measurements (93598), chest X-rays (71045, 71046), pulse oximetry (94760–94762), gastric intubation (43752, 43753), temporary transcutaneous pacing (92953), ventilator management (94002–94004, 94660, 94662), and vascular access such as 36000, 36410, 36415, 36591, and 36600. Intubation, central lines, arterial lines, chest tubes, and CPR are billed separately, and their time must come out of the critical care total.
Tele-ICU programs bill Medicare telehealth critical care consults with G0508 (initial) and G0509 (subsequent), which carry their own time and originating-site requirements. Commercial payers set separate rules for remote intensivist coverage.
ICU patients arrive through the emergency department, often without verified coverage. Wrong primary payers, unrecorded secondary coverage, and retroactive Medicaid eligibility are found after the stay, when the claim has already been denied.
The note has to show the critical illness (for example, acute respiratory failure, septic shock, or multi-organ dysfunction), the interventions the clinician directed, and the total critical care time, excluding separately billed procedures.
Medicare allows an E/M visit and critical care on the same day only when the E/M came first, the patient wasn't critically ill at that time, and modifier 25 is used. Medicare also treats intensivists of the same specialty in the same group as one physician for critical care time, so separate claims for each are denied.
Medicare allows split/shared critical care between a physician and an APP with modifier FS, billed under the clinician who provided the substantive portion. Surgeons billing unrelated critical care during a global period need modifier FT, and teaching-physician claims need documentation of the physician's own time.
Qualigenix fixes intensivist billing by auditing time, procedures, and clinician attribution on every critical care claim before it is sent.
Coders read the note for critical illness and intervention, not ICU location, and choose between critical care and inpatient E/M on that basis.
We apply the Medicare 104-minute threshold to Medicare claims and the CPT time table to payers that follow it, so each claim carries the units its payer allows.
We bill every separately payable procedure and subtract its time from the critical care total, which keeps both the procedure and the time unit defensible.
We bill Medicare telehealth critical care consults with G0508 and G0509 and follow each commercial payer's rules for remote intensivist coverage.
We run coverage discovery on unverified ICU admissions and rebill to the correct primary and secondary payers, including retroactive Medicaid.
When a note lacks a critical illness statement or a total-time statement, we send it back to the clinician with the specific gap before billing.
Our denial team overturns 79% of the denials it works, with an average appeal turnaround under 9 days. Concurrent-care appeals include each clinician's distinct role and time.
We audit modifier FS, 25, and FT use each month against Medicare critical care policy and the documentation behind each claim.
A 3-provider podiatry group with roughly 60% Medicare payer mix carried $412,000 in A/R, 38% of it past 120 days. Routine foot care claims (11720, 11721, 11055–11057) had stalled on inconsistent Q7/Q8/Q9 modifiers and class-finding documentation, so payers held or partially paid and nobody worked the remainder. Medicare crossover to secondaries was not being posted, and small patient balances were written off.
We ran a full A/R aging segmentation, worked claims by payer and denial reason rather than by date, rebilled the stalled routine-care claims with corrected modifiers, and reactivated secondary and crossover billing.
A solo podiatrist coding 320 encounters a month was stuck at 82% first-pass acceptance. Routine foot care went out without the systemic-condition diagnosis pairing and class findings Medicare requires, so it read as non-covered. Wound debridement was coded to the wrong depth (11042 for skin and subcutaneous where the note supported 11043 for muscle and fascia). Same-day E/M with a procedure went out without modifier 25 and got bundled.
We rebuilt the coding workflow: diagnosis-to-CPT pairing rules for at-risk foot care, correct Q-modifier logic, depth-based debridement coding tied to the operative note, and disciplined use of modifiers 25 and 59/XS.
A 2-location podiatry practice sat at a 19% denial rate, mostly Medicare routine-foot-care and nail-debridement rejections. The denials clustered in three buckets: medical-necessity rejections on routine foot care (missing qualifying diagnosis and class findings), frequency-edit denials on nail debridement billed inside the 60-day window, and missing Q modifiers that flagged services as non-covered.
We built a front-end denial-prevention layer, checking eligibility and coverage against payer LCDs before claims went out, plus a structured appeal workflow with documentation templates mapped to each denial reason.
Qualigenix codes critical care by service type, because time-based critical care, procedures, and consults follow different rules.
Codes: 99291, 99292. Time-based critical care for adults, with units set by each payer's time threshold.
Qualigenix supports intensivist groups, pulmonary and critical care practices, hospital-based ICU teams, tele-ICU programs, pediatric and neonatal intensivists, critical care NPs and PAs, and hospitalist groups that cover ICUs.

Qualigenix prices intensivist billing after reviewing your encounter volume, payer mix, facilities, and the services you want to hand over. Most critical care groups start with a free billing audit so the quote reflects real numbers.
Intubation, central lines, arterial lines, chest tubes, thoracentesis, paracentesis, and CPR are billed separately, with their time taken out of the critical care total. Chest X-ray interpretation, pulse oximetry, ventilator management, and gastric intubation are bundled into critical care.
We bill split/shared critical care under the clinician who provided the substantive portion, add modifier FS, and check that the note records each clinician's time.
Yes. We work existing critical care claims by denial reason and timely-filing limit, starting with the highest-value accounts. A free AR review shows how much is still recoverable.
Medicare pays one unit of 99292 after 104 total minutes of critical care, a full 30 minutes beyond the 74 minutes covered by 99291. Payers that follow CPT guidance allow 99292 from 75 minutes.
Yes. We bill Medicare telehealth critical care consults with G0508 and G0509 and bill remote intensivist coverage to each commercial payer's policy.
Qualigenix works across 133 EMR/EHR platforms and bills from the EHR and charge-capture tool your group already uses. We confirm system access during the free billing audit.
Qualigenix's average onboarding time is 6 days. That covers system access, payer enrollment checks, and coder assignment before we take over claim submission.
