Critical Care Medicine Billing Services

Critical care is billed on time, not on location. A patient in an intensive care bed does not automatically qualify for critical care billing, and a patient in an emergency department hallway can qualify if the clinical picture and the time support it. The claim stands or falls on documented qualifying time, high-complexity decision making, and a condition that threatens one or more vital organ systems. Miss the time threshold or count time that belongs to a separately billed procedure, and the claim denies or downcodes.
MedPlus RCM provides medical billing, coding, credentialing, and denial management for critical care practices, built around the specialty’s actual code families and payer requirements.

Critical Care Medicine billing challenges

Critical care uses two time-based codes. Code 99291 covers the first 30 to 74 minutes of qualifying critical care on a given calendar date, and code 99292 is an add-on for each additional 30-minute block beyond that first window. The minimum threshold is 30 minutes: if total qualifying time on a date falls below 30 minutes, the encounter must be billed with a regular evaluation and management code instead. Time does not need to be continuous, and qualifying blocks across the day can be added together, but all of the time must be on the same calendar date and must be documented.
What counts as qualifying time is narrow. Time spent in direct care, reviewing results, discussing the case with consultants or family, and documenting the encounter can count, but time spent performing separately billable procedures must be excluded from critical care time. Procedures that are bundled into critical care, such as interpretation of blood gases, chest X-ray interpretation, pulse oximetry, and ventilator management, are not reported separately, and their time is part of critical care time. Bedside procedures that are separately reportable, such as central line placement, intubation, and chest tube placement, are billed separately, and the critical care service is reported with modifier 25 when a significant, separately identifiable critical care service happens the same day as a procedure.
Attribution rules add another layer. Only one practitioner can bill for critical care during a specific time period, even when more than one physician is managing the patient, and code 99291 can only be reported once per patient per calendar date by the same physician or same-specialty group. The note must support the critical condition, the interventions, and the total time, because critical care claims are a frequent audit target. Neonatal and younger pediatric critical care follow a different model, using per-day codes based on age rather than time, and those cases must not be coded with the adult time-based codes.

Frequently asked questions

What is the minimum time for critical care billing?
Qualifying critical care time must reach at least 30 minutes on a calendar date. Below 30 minutes, a regular evaluation and management code must be used instead.
Does critical care time have to be continuous?
No. Qualifying blocks of time across the same calendar date can be added together, as long as the provider is immediately available to the patient during that time.
Can two physicians bill critical care for the same time period?
No. Only one practitioner can bill for critical care during a specific time period, even when several physicians are involved in the patient’s care.
Do procedures performed during critical care count toward critical care time?
Time spent on separately billable procedures must be excluded from critical care time. Services bundled into critical care, such as ventilator management and blood gas interpretation, are not reported separately.
What does MedPlus RCM charge?
A performance-based percentage of successfully collected revenue. If you don’t get paid, we don’t get paid.
