What is CPT Code 31231

CPT code 31231 is used to describe a diagnostic nasal endoscopy procedure. This procedure involves the use of a flexible or rigid endoscope to visually examine the nasal passages and sinus openings. It is typically performed by an ENT (ear, nose, and throat) specialist to diagnose conditions such as sinusitis, nasal polyps, or other abnormalities within the nasal cavity. The endoscope provides a detailed view, allowing the physician to assess the health of the nasal structures and determine the appropriate course of treatment.

Does CPT 31231 Need a Modifier?

For CPT code 31231, which pertains to nasal endoscopy for diagnostic purposes, the following modifiers may be applicable depending on the specific circumstances of the procedure:

1. Modifier 22 (Increased Procedural Services): This modifier is used when the work required to perform the procedure is substantially greater than typically required. Documentation must support the substantial additional work and the reason for it.

2. Modifier 50 (Bilateral Procedure): If the nasal endoscopy is performed on both sides (bilaterally), this modifier should be used to indicate that the procedure was performed on both nasal passages.

3. Modifier 52 (Reduced Services): This modifier is applicable when the procedure is partially reduced or eliminated at the physician's discretion. It indicates that the service provided was less than usually required.

4. Modifier 59 (Distinct Procedural Service): This modifier is used to indicate that a procedure or service was distinct or independent from other services performed on the same day. It is often used to bypass National Correct Coding Initiative (NCCI) edits.

5. Modifier 76 (Repeat Procedure by Same Physician): If the same physician repeats the nasal endoscopy on the same day, this modifier should be used to indicate the repeat service.

6. Modifier 77 (Repeat Procedure by Another Physician): If a different physician repeats the nasal endoscopy on the same day, this modifier is appropriate.

7. Modifier 78 (Unplanned Return to the Operating/Procedure Room by the Same Physician Following Initial Procedure for a Related Procedure During the Postoperative Period): This modifier is used if the patient returns to the operating room for a related procedure during the postoperative period.

8. Modifier 79 (Unrelated Procedure or Service by the Same Physician During the Postoperative Period): This modifier is used when the nasal endoscopy is performed during the postoperative period of another procedure, but it is unrelated to the original procedure.

9. Modifier 80 (Assistant Surgeon): If an assistant surgeon is required during the nasal endoscopy, this modifier should be used.

10. Modifier 81 (Minimum Assistant Surgeon): This modifier is used when a minimum assistant surgeon is required for the procedure.

11. Modifier 82 (Assistant Surgeon (when qualified resident surgeon not available)): This modifier is used when an assistant surgeon is necessary because a qualified resident surgeon is not available.

12. Modifier 99 (Multiple Modifiers): When more than four modifiers are necessary to describe the service, this modifier indicates that multiple modifiers are being used.

Each modifier should be used in accordance with the specific circumstances of the procedure and the payer's guidelines. Proper documentation is essential to support the use of any modifier.

CPT Code 31231 Medicare Reimbursement
