Description

This document addresses procedures performed in the ambulatory or outpatient surgery centers.

Ambulatory surgery refers to surgical or invasive diagnostic procedures performed by qualified providers in ambulatory or dedicated surgical suites with pre-procedural and immediate post-procedural care on the same day or observation admissions without hospitalization (Patient Selection Criteria for Ambulatory [Same Day] Surgery VHA Handbook).

Note: Please see the following related documents for additional information:

Clinical Indications

Note: The medical necessity of the procedure may be separately reviewed against the appropriate criteria. 

Medically Necessary:

The use of an outpatient or ambulatory surgery center (ASC) facility, rather than an office-based setting, is considered medically necessary when any of the following criteria are met:

  1. The procedure must be of a level of complexity that it may not be performed in a less intensive setting such as an office-based setting, but also not so complex as to require immediate access to specific services of a medical center/hospital setting or post-operative recovery in an inpatient facility. For example the procedure’s complexity requires one of the following, including but not limited to:
    1. need for anesthesia or sedation beyond topical anesthesia, digital block, or local anesthesia with concomitant need for monitoring of physiologic parameters beyond intermittent checks of vital signs; or
    2. need for recovery period of significant duration beyond the capacity of a physician’s office;
      OR
  2. The individual has clinical conditions which may compromise the safety of an office-based procedure, including but not limited to:
    1. medical conditions which require enhanced monitoring, medications or a prolonged recovery period; or
    2. increased risk for complication due to severe comorbidity, such as that evidenced by an American Society of Anesthesiologist’s (ASA) class III or higher physical status.

Not Medically Necessary:

All other uses of outpatient or ASC facility, rather than an office-based setting, are considered not medically necessary.

Coding

Coding edits for medical necessity review are not implemented for this guideline. Where a more specific policy or guideline exists, that document will take precedence and may include specific coding edits and/or instructions. Inclusion or exclusion of a procedure, diagnosis or device code(s) does not constitute or imply member coverage or provider reimbursement policy. Please refer to the member's contract benefits in effect at the time of service to determine coverage or non-coverage of these services as it applies to an individual member.

Discussion/General Information

While hospitals continue to provide essential services for serious illness, much health care activity takes place in the ambulatory setting. Surgical practices have been transformed so that more than half of all surgery in the United States is performed on an ambulatory basis (Patient Selection Criteria for Ambulatory [Same Day] Surgery VHA Handbook). Ambulatory (or outpatient) surgery provides an efficient and flexible means to provide many surgical and therapeutic procedures without requiring an inpatient hospital admission. With advances in healthcare delivery and the advent of new technologies, the list of such services continues to evolve.

While it is important to emphasize that both the complexity of the procedure and the individual’s clinical conditions may compromise the safety of an office-based procedure, we provide the following examples of procedures which would generally not warrant use of an ambulatory or outpatient surgery center:

  1. Minor aspiration or injection procedures;
  2. Minor skin procedures such as acne surgery, incision and drainage, debridement, paring or cutting, biopsy, shaving, excision, destruction, exfoliation or electrolysis;
  3. Minor nail procedures such as trimming, debridement, evacuation of subungual hematoma or excision of nail and nail matrix;
  4. Implantation or removal of contraceptive capsules or pellets;
  5. Simple repair of superficial wounds;
  6. Removal of superficial foreign bodies including protruding surgical hardware (for example: k-wires, pins);
  7. Arthrocentesis, aspiration and/or injection procedures with or without image guidance;
  8. Low intensity ultrasound stimulation to aid bone healing, noninvasive (non-operative);
  9. Closed treatment of phalangeal, metatarsal, sesamoid, calcaneal, talus fracture, or tarsal bone fracture; without manipulation;
  10. Venipuncture services;
  11. Maxillary impression for palatal prosthesis;
  12. Insertion of pin-retained palatal prosthesis;
  13. Artificial insemination; intra-cervical or intra-uterine sperm washing for artificial insemination;
  14. Application of surface (transcutaneous) neurostimulator;
  15. Chemodenervation of salivary glands or muscle(s) (for example: for blepharospasm, hemifacial spasm);
  16. Destruction by neurolytic agent; peripheral nerve or branch;
  17. Assorted patch, scratch, prick and intradermal allergy tests.
