Clinical Context
A 54-year-old patient with chronic low back pain radiating to the left buttock presents to an interventional pain clinic for diagnostic and therapeutic management. Conservative care including physical therapy and oral analgesics provided limited relief. The provider performs a transforaminal lumbar epidural steroid injection without imaging guidance to deliver corticosteroid and local anesthetic into the epidural space at the symptomatic lumbar level to reduce inflammation around the affected nerve root and assess pain relief for diagnostic correlation. The clinical workflow includes pre-procedure evaluation (review of anticoagulation, allergies, and recent imaging), informed consent, sterile field preparation, local skin anesthesia, needle or catheter insertion into the lumbar/sacral epidural space using anatomical landmarks, injection of the therapeutic agent, monitoring for immediate complications, and post-procedure discharge instructions with activity restrictions and follow-up planning.
Coding Specifications
| Modifier | Description | When to Use |
|---|
25 | Significant, separately identifiable evaluation and management service by the same physician on the day of a procedure | Use when a distinct E/M visit is performed and documented on the same day as the injection |
| 52 | Reduced services | Use when the service was partially reduced or not completed as described
| 53 | Discontinued procedure | Use when the procedure was started but terminated due to extenuating circumstances
| 59 | Distinct procedural service | Use when another service on the same day is distinct and separate from the injection
| 62 | Two surgeons | Use when two surgeons work together as primary surgeons on a single procedure (rare for this injection)
| 76 | Repeat procedure by same physician | Use when the same physician repeats the procedure later the same day (note: 76 not in provided list; therefore not included)
| 77 | Repeat procedure by another physician | Use when another physician repeats the procedure later the same day (note: 77 not in provided list; therefore not included)
| 50 | Bilateral procedure | Use when the injection procedure is performed bilaterally and service allows modifier for bilateral involvement
| 51 | Multiple procedures | Use when multiple distinct procedures are performed during the same session
| 59 | Distinct procedural service | Use when services that are normally bundled are not usually reported together but are distinct
| 73 | Discontinued outpatient hospital/ambulatory surgery before anesthesia administration | Use when the outpatient procedure was discontinued prior to anesthesia in the ambulatory setting
| 52 | Reduced services | Use when the procedure is intentionally reduced or not completed as documented
