In some cases, procedure codes alone do not provide sufficient detail to convey the exact service or procedure performed to the payer. In these situations, Medicare or private insurers may require physicians to append a modifier to the procedure code listed on the claim to clarify the nature of the service.
Physicians may use either a CPT modifier, developed by the AMA CPT Editorial Panel, or, when a suitable CPT modifier is unavailable, CMS may require the use of its own HCPCS modifiers. Below are three modifiers frequently used in pain management practices, along with guidance on their appropriate application.
Modifier -22: Increased Procedural Services
Modifier -22 is used when the complexity or effort required for a procedure is significantly greater than usual. This modifier should only be added when the documentation clearly supports the increased time, intensity, technical difficulty, or other factors that made the procedure more challenging than normal. These factors may include:
- Increased intensity or complexity of the procedure
- Extended procedure time
- Higher technical difficulty or severity of the patient’s condition
- Increased physical and mental effort required from the physician
It is important to note that modifier -22 should not be used for evaluation and management (E/M) services.
When to use Modifier -22:
- When the procedure took substantially more time than normal to complete.
- In cases involving extensive lysis of adhesions, beyond what is typically part of a standard surgical procedure.
- When obesity significantly complicates the procedure (e.g., in patients who are significantly obese, if the obesity complicates the surgical approach).
When using modifier -22, some payers may request additional documentation or even deny the claim initially, requesting further supporting evidence. Consider using clear descriptive terms, such as:
- Extensive
- Time-consuming
- Extremely difficult due to
- Very difficult to perform
- Took longer than usual
- Exacerbating circumstances
Modifier -24: Unrelated E/M Service During a Postoperative Period
Modifier -24 is used to indicate that an E/M service was provided during the postoperative period, but the service is unrelated to the original procedure. This modifier is used to inform the payer that the E/M service does not fall under the global package for the original surgery.
Important Notes about Modifier -24:
- It applies only to E/M services, not to procedures.
- Modifier -24 should not be confused with modifier -79, which applies to unrelated procedures during the postoperative period.
- Using this modifier correctly helps ensure proper reimbursement for the unrelated E/M service, as it clarifies that the service is not part of the routine postoperative care.
Modifier -25: Significant, Separately Identifiable E/M Service on the Same Day as a Procedure
Modifier -25 is used when an E/M service is provided on the same day as a procedure or service, and the E/M service is significant and separately identifiable from the procedure. This modifier is essential when the E/M service goes beyond the typical preoperative or postoperative care associated with the procedure.
The documentation should clearly show that the E/M service was distinct and necessary in addition to the procedure. The E/M service may be related to the same condition or a different one. Importantly, modifier -25 does not require a different diagnosis for the E/M service, as long as the documentation supports its separate identification.
Modifier -25 should not be used in cases where the E/M service led to a decision for surgery. In such instances, modifier -57 should be applied instead to indicate the decision for surgery.
Key Distinction:
- Modifier -25 is for significant, separately identifiable E/M services.
- Modifier -57 should be used when the E/M service led to a decision to perform surgery.
- For separately identifiable non-E/M services, use modifier -59 (Distinct Procedural Service).
By using these modifiers correctly and ensuring adequate documentation to support their application, pain management practices can help avoid claim denials and ensure appropriate reimbursement.
Frequently Asked Questions (FAQ)
1. What is the purpose of using modifiers in medical billing? Modifiers are used in medical billing to provide additional information to the payer about the specifics of a procedure or service, clarifying circumstances that are not fully captured by the procedure code alone. This helps ensure accurate reimbursement for services rendered.
2. Can I use modifier -22 for any procedure? No, modifier -22 should only be used when the physician’s work exceeds the usual expectations for a particular procedure due to increased time, complexity, or difficulty. It should be well-supported by documentation detailing the reasons for the additional work, such as technical difficulty or severity of the patient’s condition.
3. How do I know when to use modifier -24? Modifier -24 is used to indicate that an evaluation and management (E/M) service was provided during a postoperative period, but it is unrelated to the original surgery. It should only be applied to E/M codes, not procedural codes, and should not be confused with modifier -79.
4. Can I use modifier -25 if the E/M service is related to the procedure? No, modifier -25 is specifically for situations where the E/M service is separately identifiable and significant in addition to the procedure, even if the E/M service is related to the same condition. The E/M service must be clearly documented as distinct from the procedure.
5. What should I include in the documentation when using modifier -22? When using modifier -22, ensure the documentation supports that the procedure required significantly more time or effort than usual. Use descriptive terms like “extensive,” “time-consuming,” or “extremely difficult” to clearly explain the reasons for the additional work required.
6. Are there any other modifiers used for pain management practices? While modifier -22, -24, and -25 are commonly used, there are several other modifiers that may apply in specific cases. Always refer to the latest coding guidelines and payer policies to ensure correct modifier usage.
