When Modifier 22 May Be Considered

Trek Health ingests and normalizes Transparency in Coverage data and payer policy updates to give provider organizations a clear view of how commercial reimbursement behaves across markets, payers, and services. Our platform transforms raw payer disclosures into structured intelligence that supports contract evaluation, payer negotiations, and service line strategy. By combining market benchmarks with ongoing policy visibility, Trek helps teams identify variability, risk, and opportunity in commercial reimbursement. The result is faster insight, stronger negotiating positions, and more informed financial decisions.

When modifier 22 may justify additional reimbursement

Modifier 22 may be considered when the work effort was substantially greater than usually required. Documentation requirements and exclusions are specified.

ALL of the following

Provider appended modifier 22 to indicate the service/procedure was substantially greater than typically required.
Thorough documentation exists in the medical record (operative report, anesthesia record when applicable) explaining and quantifying how the procedure was more complex than usual.
Documentation demonstrates reasons such as increased time, increased intensity, technical difficulty, increased physical/mental effort, or severity of the patient's condition.
For anesthesia field avoidance: documentation included in the anesthesia record AND base units < 5 AND/OR patient position required other than supine.Base units < 5

When modifier 22 is not justified

Examples of statements or situations that are insufficient to support modifier 22 and service types where modifier 22 should generally not be appended.

ANY of the following

Generalized or conclusory statements (e.g., 'surgery took an additional two hours', 'surgery for an obese patient', 'this was a difficult procedure') without detailed quantification/comparison to usual work.
If the additional work has a specific procedure code (use that code instead).
Procedures delayed or impacted by equipment malfunction.
Procedures prolonged or complicated by the surgeon's choice of approach (e.g., difficulty gaining access due to chosen technique).
If a procedure code does not have a global period of 0, 10, or 90 days.

What Providers Must Do

Documentation Required

Documentation required to support Modifier 22

Provide thorough operative or anesthesia reports that detail how and quantify why the procedure required substantially more work than usual. A brief letter or statement outside the medical record is insufficient. For anesthesia field avoidance, documentation must be included in the member's anesthesia record and demonstrate base units < 5 and/or a patient position other than supine.

Affected codes: 22

Billing Rule

Claim submission and coding expectations

Append modifier 22 on professional claims where appropriate; usage does not guarantee additional reimbursement. Claims must be submitted using HIPAA‑approved code sets and follow industry coding guidelines. The plan may request supporting documentation; failure to adhere to coding and billing policies may impact claims processing and reimbursement.

Affected codes: 22

Denial Risk

Risks of inappropriate use

Modifier 22 appended without adequate, detailed documentation or when used for excluded service types may be denied or not receive additional payment.

Examples of excluded or inappropriate uses: E/M services; most anesthesia services (except field avoidance where criteria met); DME services; unlisted procedure codes; procedures with a specific alternative code; procedures without global periods of 0, 10, or 90 days.
Generalized or conclusory statements (e.g., 'surgery took an additional two hours', 'this was a difficult procedure') are insufficient justification.

Policy Scope & Context

This policy defines billing, documentation, and reimbursement expectations for appending Modifier 22 (Increased Procedural Services) to professional (physician) claims when a service or procedure required substantially greater work than is typically required. Use of Modifier 22 is a provider representation that the work performed was substantially greater than usual and does not guarantee additional reimbursement; the plan may request supporting documentation and may review claims for adherence to coding and billing policies.

Thorough clinical documentation is required to support additional payment when Modifier 22 is appended. The operative report (and when applicable the anesthesia record) should clearly explain and quantify how the procedure was more complex than usual, including reasons such as increased time, increased intensity, technical difficulty, increased physical/mental effort, or severity of the patient’s condition. A brief letter or statement outside the medical record is insufficient.

Modifier 22 is not applicable to services billed on the UB-04 claim form; this policy applies to professional claims only. Certain service types are generally excluded from Modifier 22 (for example, E/M services, most anesthesia services except documented field avoidance, DME, and unlisted codes), and generalized or conclusory statements without quantification are not sufficient justification.

For anesthesia-related field avoidance, additional payment consideration requires that the anesthesia record documents the substantial additional work and that either the base units are < 5 and/or the patient position required is other than supine.

Blue Shield of Illinois reserves the right to request supporting documentation and to use reasonable discretion in applying this policy. If a conflict exists between this Clinical Payment and Coding Policy and a member’s plan document or a provider’s contract, the plan document or provider contract will govern.
