Looking for help with anaesthesiology billing? Having a reference list of common fee codes on hand can go a long way towards saving you time and reducing your administrative workload. This fee listing includes codes for general and regional anaesthesiology procedures, resuscitation and critical care, monitored anaesthesia care, and any other medical procedure carried out by the anesthesiologist at the request of the attending physician. These fees are payable to all anesthesiologists, with the exception of consultations and continuing care by consultants, which are payable only to certified specialists in anesthesia.

Guidelines and Criteria:

MSP begins your billable time when you first enter the operating room for the purpose of providing anaesthetic. Your time ends when you leave and when the patient can be safely left in the care of nursing staff. While you are working, you should calculate your time in 15 minute increments or parts thereof – for example, if your final period of anaesthetic is 9 minutes, you would be able to bill for the full 15. Other guidelines to keep in mind include:

Routine P.A.R (Post-Anesthetic Recovery) care
Any time you spend with the patient after your anaesthetic in the P.A.R for routine problems should be billed at the same rate as the anesthetic and included in the procedural fee for the anaesthesia. 

Additional Procedures
When you perform more than one surgical, diagnostic, or therapeutic procedure during the same session, the rate for your total anaesthetic time will be the rate for whichever procedure has the highest procedural rate. 

Anaesthetic Procedural Fees
The procedural fee for your anaesthesia time covers all of the services you’ll render during the procedure, except for the anaesthetic procedural fee modifiers and acute pain management. It is calculated by multiplying the intensity/complexity level of the anaesthesia by the anesthetic time per 15 minute interval. 

Anaesthetic Procedural Fee Modifiers
These modifiers pay you an additional amount over and above your anesthetic procedural fee. They apply to all of your general, regional, and monitored anesthetic care for any surgical, therapeutic, and/or diagnostic procedures you might perform. You cannot use them with diagnostic or therapeutic anaesthesiology fees. 

Keep in mind that some modifiers may require additional information. For example, when billing the modifier code 00169, your claim must include a note indicating the patient’s body mass index (eg. BMI 35.5)   

Consultations and Anaesthetic Assessments
These are not payable in addition to critical care fees. However, if they are done prior to surgery (for example, if you see a patient a week before a procedure to consult with them on their surgical risk) then you would be able to bill for this. 

Consultations are allowed once per 6-month period. All types of consultations (as outlined below) need to have been referred to you by a physician or nurse practitioner. 

Procedure Expectations Allowable Frequency
Consultation Full medical history required, must be referred to you by another physician or nurse practitioner. Once per 6 month period
Repeat Consultation Full medical history required, must pertain to different medical issue than previous consultation. Must be referred to you by another physician or nurse practitioner. Once per 30 day period, but only for a completely different medical issue
Limited Consultation Full medical history not required. Must be referred to you by another physician or nurse practitioner. Once per 30 day period, 
Complete Examination  Full medical history required; less time spent with the patient than a consultation. Does not require a referral and can be both a scheduled appointment or emergency visit.  Once every 12 month period (if you need to bill this twice for a patient within 12 months you need to have a note explaining why). 

Acute Pain Management
These fee codes apply to any services you might provide relating to the management of what is deemed ‘acute’ pain in certain categories of patients. These include post-operative surgical patients, surgical patients who do not necessarily undergo surgery but have problems with acute pain, and medical patients who have acute pain problems. These listings are not applicable to pain management during labour.

All acute pain management billing codes can be used in combination with the out-of-office service charges and continuing care surcharges.

The acute pain management codes cannot be applied to claims for critical care fee items 01088, 01412, 01413, 01422, 01423, 01432, 01433, 01442 and 01443 if the anesthesiologist trying to claim them is capable of acute pain management.

Diagnostic/Therapeutic Fees
Anaesthesia fees for diagnostic and therapeutic services can be billed but are not eligible for the out-of-office or continuing care service charges. They are also not allowed to be used with anaesthetic procedural fee modifiers. 

Dual Anesthesiologists
In some situations, providing care to a patient may require two anaesthesiologists to be present for the procedure. In this case, both doctors may charge their full fee – however, when billing MSP for these fees, both doctors need to support the need for these charges with a written statement. 

If one anaesthesiologist takes over from another one, partially through a procedure, the total fee billable by both anesthesiologists should not exceed the fee that would have been billed had the procedure been performed by only one doctor (if the replacement did not occur). 

Common Fee Codes:

Here’s an overview of some of the most commonly used codes: 

Pre-Anesthetic Evaluation Fees:

01151: Pre-anaesthetic evaluation – standard

  • Applicable to certified anesthesiologists only.

13052: Anaesthetic evaluation – non-certified anaesthetist

  • Used for in-patient visits where a separate visit prior to the anaesthetic is required. If you’re performing a visit immediately prior to the anaesthetic, it will be paid using the anaesthetic intensity/complexity level of the procedure itself and 01151 – this code will not be paid in addition.
  • Can also be used for out-patient visits where a separate visit for an anaesthetic assessment is required (such as in a pre-anesthetic clinic).


01015: Consultation, anaesthesia

  • This code is used when a certified anaesthesiology specialist is requested for a patient assessment because of the complexity, obscurity, and/or seriousness of the case.

01115: Consultation – repeat/limited – anaesthesia

  • This is used when a repeat consultation is necessary for the same condition within six months and done by the same consultant.
  • It is also used for a limited consultation when in the opinion of the consultant the problem does not warrant 01015.

01016: Consultation, mgmt of complicated chronic pain

  • This code is used in consultations for complex diagnostic and/or therapeutic chronic pain management problems that need a comprehensive history and a physical examination.

01116: Consultation – repeat or limited – diagnostic/pain mgmt

  • Used when, in the opinion of the consultant, the diagnostic and/or therapeutic chronic pain management problem is of a more limited nature.  
  • If the same physician sees a patient for a consultation within six months of billing 01016 for the same problem, then they would also use this code.

01107: Office visit – anaesthesia

  • This fee code applies to patient visits conducted in a private office setting where the physician has an increased overhead.

01155: Telehealth Anesthesiology Consultation:

  • This is used for telehealth sessions conducted by a certified specialist in Anesthesiology because of the complexity, obscurity and/or seriousness of the case. Includes appropriate history and an appropriate physical examination, as well as a review of pertinent radiological and laboratory findings and a written report.

 Visit / Evaluation:

01107: Office visit.

  • Not paid with other listings.

01108: Hospital visit (weekday)

  • Not paid with other listings.
  • Applies only on weekdays, excluding statutory holidays.
  • Out-of-Office Hour Premiums are not applicable.

01109: Hospital visit (Saturday, Sunday, or statutory holiday)

  • Not paid with other listings  
  • Applies only on Saturday, Sunday, or statutory holidays
  • Out-of-office Hour Premiums are not applicable

Call Outs & Continuing Care Premiums 

A call out is a premium added when you are called from outside of the hospital to come and care for a patient. During weekdays the call must be placed prior to 8:00am or after 6:00pm. On weekends the call must be placed after 8:00am.

REMINDER: If you’re called during regular weekday hours you’d bill an emergency visit instead, which covers both the visit and the surcharge.

Continuing Care

If you have logged a Call Out charge and then continue to see additional patients you would be entitled to bill continuing care surcharges for each 30 minutes after the initial 30 minutes you spent with the patient you were initially called to see.

If you see multiple patients in a 30 minute block you would only log the continuing care on the last patient in that block but for the entire 30 minute period. You must also note CCFPP in the MSP note field to tell MSP that these patients were seen following your initial call out to the hospital.

Continuing Care Rules

Timing begins after the first 30 minutes for consultations, visits or anesthetic evaluations. Payment is based on one half-hour of care or major portion thereof (at least 15 mins.). This means that your first continuing care surcharge is only eligible after 45 minutes of continuous care (30 mins. for the refractory period plus the major portion of 15 minutes).

Timing for the continuing care premium is based on the total time spent providing continuous care, not the number of patients you see. For example, if you see 3 patients within 30 minutes then you would only add the continuing care premium on the last patient, but for the entire 30-minute duration.

To apply these surcharges on Dr. Bill, log your consult or visit with the patient. On that claim toggle ‘Call Out & Continuing Care’. Don’t forget to enter the Call Time, Start Time & End Time for your encounter. Our app will automatically apply the correct Out of Office premiums to your claim.

Reminder: Only toggle Call-Out on the first patient, to show that it was the first. For the following claims just toggle Cont.Care. If you need to claim a call out on its own or aren’t using Dr. Bill then use the following fee codes: 

Call Out Fee codes:
