The Anesthesia Modifier P01169
When billing for many anesthesia services anesthesia modifiers are used in order to indicate the different time units involved in the anesthesia service. On January 1st, 2019, MSP introduced a new fee code for Anesthetic modifiers, P01169.
This fee code is based off of your patients BMI (Body Mass Index) score, which is the estimate of your patient’s body fat based on their weight and height. The modifier works on increments of 15 minutes. Recently however, MSP increased the amount of P01169, so it now pays $20.69 per 15 minutes (as opposed to the beginning of the year when it was $20.54.)
|Fee Code||Description||Amount $|
|P01169||BMI ≥ 35 - per 15 minutes or part thereof||$20.69 (a .15 increase from January 1st).|
Restricted to certified specialists in Anesthesiology
or 01111 are also payable.
Applicable to all patients who are 19 years of age or older, with a BMI of 35 or more. It’s also applicable for patients who are younger than 19 who have a BMI with at least 97th percentile adjusted for age and gender.
The patient’s BMI must be provided in the claim note record and documented on the patient’s anesthetic record.
