Ambulatory Surgery Centers
Billing for hospital stays and procedures can only use the ICD-10 book of codes if the procedures are performed as inpatient procedures, meaning there is at least a day of recovery time in the hospital.
For instance, if there was a patient who needed to be monitored in the hospital for cardiac output, the billing code according to the ICD would be 4A1209Z, where “4” marks the section as Measurement and Monitoring, “A” represents physiological systems, “1” represents the root operation as Monitoring, “2” denotes the heart as the body part being monitored, “0” shows that it is an open approach, “9” shows that is monitoring output, and “Z” indicates that no further qualifiers are needed.
CPT codes are also used in hospital billing. However, they differ in several ways. For one, the CPT codes can be seen by physicians, patients, and billers, as well as insurance companies.
An ambulatory surgery center is also known as an outpatient procedure center. In an ambulatory surgery center, procedures are performed on patients and are completed the same day, to a point where the patient can leave the facility immediately following surgery.
Ambulatory surgery centers use CPT codes when billing insurance agencies for patient visits. The codes 99201-99215 are designated for outpatient procedures. Each code is designated to a specific patient who meets specific criteria.
For example, if a new patient comes in for an outpatient procedure he or she will be billed using one of the following codes: 99201, 99202, 99203, 99204, or 99205. The differences between these codes lie in the amount of time a physician spends with that patient before the surgery. That time is billed differently.
If the patient coming in for an outpatient procedure is not a new patient, he or she will be billed according to one of the following codes: 99211, 99212, 99213, 99214, or 99215. The differences between these codes lie also in the amount of time spent with a patient before he or she has his or her procedure.
