CPT 20552: Trigger Point Injection, 1 or 2 Muscles
CPT 20552 reports injection(s) of one or two muscles for trigger points, regardless of how many injections are given. In 2026 Medicare pays about $51.77 non-facility and $35.74 facility, with a 000-day global period. Coding is driven by the number of muscles, not needle sticks.

What is CPT 20552 used for?
CPT 20552 reports injection(s) of one or two muscles for trigger point therapy. It is used for myofascial pain, where a palpable taut band or trigger point in a muscle is injected with anesthetic, saline, or a small amount of steroid to relieve spasm and pain.
The companion code 20553 covers three or more muscles. There is no add-on code; you pick one of the two based on how many muscles were treated in the session.
How much does 20552 pay in 2026?
Under the 2026 Medicare fee schedule, 20552 allows about $51.77 non-facility and $35.74 facility.
| Setting | 2026 Medicare allowed |
|---|---|
| Non-facility (office) | ~$51.77 |
| Facility (hospital outpatient) | ~$35.74 |
Example: a physician injects trigger points in the right trapezius and left rhomboid in one visit. That is two muscles, so you bill a single unit of 20552 at about $51.77. Check your locality figure with the Medicare fee calculator.
How do you count muscles for 20552?
The counting rule is the single most misunderstood part of trigger point coding. What matters is the number of distinct muscles, never the number of injections:
- Count each distinct muscle treated once.
- Multiple trigger points in the same muscle still equal one muscle.
- One or two muscles: 20552. Three or more: 20553.
What MUE and modifier rules apply?
Both 20552 and 20553 carry a MUE of one unit per date, so you cannot report multiple units for a single session. The 000 global period means no post-op days are bundled. A same-day E/M can be reported with modifier 25 when a significant, separately identifiable evaluation is documented. Every trigger point injection should meet medical necessity for myofascial pain. For joint-based injections instead, see 20610.
Frequently asked questions
In 2026 the national non-facility allowed amount is about $51.77, and the facility rate is about $35.74. Medicare pays 80 percent and the patient or secondary plan owes the 20 percent coinsurance after the deductible. Any injected drug is generally included, not billed separately as with joint injections.
Per muscle, not per injection. 20552 covers one or two muscles regardless of how many needle sticks are used. Multiple trigger points within the same muscle still count as one muscle. Report only one code per session: 20552 for one or two muscles, or 20553 for three or more.
20552 covers trigger point injections in one or two muscles; 20553 covers three or more muscles. Count distinct muscles treated, not injections or trigger points. You never report both codes together, and neither should be billed with more than one unit for the same date.
