Extra units payable in addition to basic units when an anaesthesiologist administers an anaesthetic to a patient classified as ASA III (patient with severe systemic disease limiting activity but not incapacitating).

When to Use

Use E022C for patients with stable, severe systemic disease such as poorly controlled hypertension, symptomatic COPD, or stable angina that limits daily activity.
Apply this code when the patient meets ASA III criteria during the pre-operative assessment, regardless of whether the surgery is elective or urgent.
Use E022C in conjunction with standard anaesthesia time units for procedures like colonoscopies (E032C) or ocular surgeries (E023C) when the patient's systemic status meets the ASA III threshold.

Common Pitfalls

Billing E022C alongside E030C or E031C for nerve block procedures will result in automatic rejection as these are mutually exclusive.
Attempting to bill E022C for obstetrical epidural maintenance (P016C) is a common error; it is only eligible for payment with the initial catheter introduction (P014C).
Upcoding to E017C (ASA IV) for a patient who is merely ASA III is a frequent audit trigger; ensure the patient's condition is severe but not an immediate threat to life.

Billing Tips

Always append the 'C' suffix to the procedural code to ensure the premium is correctly linked to the anaesthesia service.
Document the specific ASA III criteria (e.g., 'severe COPD') in the anaesthesia record to justify the extra units in the event of a post-payment review.
