The Bundled Service and the Modifier Decision
A physician performs a minor procedure (a skin lesion excision) and, during the same encounter, performs a separately identifiable evaluation and management service for an unrelated complaint (new onset chest pain). The documentation supports both the procedure and a significant, separately identifiable E/M. The coder is preparing the claim and considers appending modifier 25 to the E/M code. The payer's policy states that modifier 25 is payable only when the E/M is significant and separately identifiable from the procedure. The coder is unsure whether the chest pain evaluation qualifies because it occurred during the same visit as the excision.
1. Determine whether modifier 25 is appropriate and explain the criteria the coder must apply.
Read the worked answer
Modifier 25 may be appropriate if the E/M service is significant, separately identifiable, and above and beyond the usual preoperative and postoperative work of the procedure. The coder must review the documentation to confirm that the chest pain evaluation involved a distinct history, exam, and medical decision-making unrelated to the skin excision. The fact that both occurred in the same encounter does not automatically disqualify the E/M; the key is whether the E/M was separately identifiable. The coder should ensure the documentation supports the E/M level independently and that the procedure note does not absorb the E/M work. If the criteria are met, modifier 25 is appended to the E/M code.
2. Explain the compliance risk if modifier 25 is appended without adequate documentation and how the coder should proceed.
Read the worked answer
Appending modifier 25 without documentation of a significant, separately identifiable E/M is a compliance risk because it can result in payment for services not supported, potentially violating payer rules and the False Claims Act. The coder should not append the modifier based on the mere presence of a second complaint; the documentation must show the separate E/M work. If the documentation is unclear, the coder should query the physician or review the note for distinct elements. The coder should document the rationale for the modifier in the claim file and retain the supporting documentation. Audits should monitor modifier 25 use for patterns of overuse.
