Fracture care billing: global periods, casting, and follow-up.
Fracture care is billed as a package, not a visit, and the package's boundaries trip up more claims than the treatment codes themselves. The global period decides what's already paid for and what's a separate line; the wrong ICD-10 7th character on a routine follow-up denies a claim that was otherwise correct. This guide covers the 10-day-versus-90-day distinction, exactly what's bundled versus separately billable, co-management billing with modifiers 54/55/56, and the episode-of-care diagnosis logic that decides whether a follow-up visit pays.
Key takeaways
- The global period is set by the treatment method, not the fracture. Closed treatment without manipulation typically runs the shorter, 10-day family; manipulation, percutaneous fixation, or ORIF typically runs the 90-day family — check the specific code, not the injury.
- Only the first cast/splint and routine follow-up are bundled. Healing X-rays, casting and splinting supplies, and any DME dispensed are separately billable — and routinely underbilled.
- Modifiers 54/55/56 split the global fee when care is co-managed — surgical care, postoperative management, and preoperative management each bill as their own portion, documented by the date care transferred.
- The ICD-10 7th character has to match the visit type, not the calendar. Billing "A" (initial encounter) on a routine follow-up inside the global window is one of the most common causes of an episode-of-care mismatch denial.
10-day versus 90-day: what actually decides it
Fracture treatment codes carry a global period like any other surgical CPT code, and the assignment tracks the treatment method rendered, not the fracture pattern or the bone involved. As a general rule: closed treatment without manipulation — the fracture is stable and simply immobilized — typically falls into the shorter global family, commonly 10 days. Closed treatment with manipulation, percutaneous skeletal fixation, and open reduction internal fixation (ORIF) typically fall into the 90-day major-procedure family, because they represent a genuine surgical intervention even when "closed treatment with manipulation" doesn't involve an incision.
| Treatment method | Distal radius example | Clavicle example | Typical global family |
|---|---|---|---|
| Closed treatment, without manipulation | 25600 | 23500 | Shorter (commonly 10-day) |
| Closed treatment, with manipulation | 25605 | 23505 | Major (commonly 90-day) |
| Percutaneous skeletal fixation | 25606 | — | Major (commonly 90-day) |
| Open treatment with internal fixation (ORIF) | 25607–25609 (by fragment count) | 23515 | Major (commonly 90-day) |
The practical trap: the same fracture, treated two different ways, lands in two different global families, and staff who default to "it's a fracture, it's 90 days" either overbill the global window on a minor closed treatment or, more often, under-recognize that a manipulated or fixated fracture blocks routine follow-up billing for a much longer stretch than they planned for. Pull the global-days value for the exact code billed, every time, rather than assuming from the injury type.
What's bundled versus what's separately billable
The global surgical package for fracture care is narrower than most billers assume. Two things are included, and everything else that touches the injury during the global window is a separate line if it's genuinely separate work.
- Routine follow-up visits related to the fracture, for the duration of the global period.
- The first cast or splint application performed the same day treatment is rendered — the application code itself isn't separately billable when restorative treatment (the fracture code) was already reported that session.
- X-rays taken to assess healing, with the appropriate radiology code — imaging is never part of the global surgical package.
- Casting and splinting supplies (the HCPCS Q-code range covering cast and splint materials), billed apart from the application code, and any re-cast or re-splint application after the first one.
- DME dispensed for the injury, such as a walking boot — its own HCPCS L-code, and its own documentation and enrollment considerations if dispensed in-office.
- An E/M for a condition genuinely unrelated to the fracture, billed with modifier 24 during the global window.
The costliest pattern we see is practices bundling supply costs into the perceived "global fee" out of habit and never billing the Q-codes or the DME L-codes separately at all. That's not a denial — it's silent underbilling, because a supply line that's never submitted never shows up anywhere to flag the loss. Audit a sample of fracture-care encounters against the actual claims submitted, not against what the global period conceptually covers, to find out whether this is happening in your practice.
Co-management: modifiers 54, 55, and 56
Fracture care frequently splits across two practices — an emergency physician or hospitalist renders the initial treatment and an orthopedist takes over follow-up, or an orthopedist performs the definitive fixation and a primary care physician or rural provider manages routine follow-up closer to the patient's home. Three modifiers report each party's share of the same global surgical package:
- 54Surgical care only. Reported by the physician who performed the fracture treatment or fixation itself, when a different physician will handle some or all of the postoperative follow-up.
- 55Postoperative management only. Reported by the physician who takes over routine follow-up care after the treating physician's involvement ends, for the remainder of the global period.
- 56Preoperative management only. Reported by a physician who evaluated and managed the patient before treatment but did not perform the treatment itself — less common in fracture care specifically than 54/55, but relevant when a separate evaluating physician is involved before a scheduled fixation.
Each party bills their own portion of the global package rather than the full fee, and the split is decided by the date care was transferred, which needs to be documented and consistent across both practices' records. Payer policy, not the CPT code itself, sets how each modifier's portion is valued relative to the whole global fee, so confirm the specific payer's split methodology if you bill co-managed fracture care routinely rather than assuming a fixed percentage. The failure mode payers catch quickly: two practices both billing without a 54/55 split for the same fracture episode, or billing overlapping date ranges — the claims contradict each other on their face and one gets recouped.
The ICD-10 7th character: why the wrong one denies a paid claim
Fracture diagnosis codes carry a 7th character that reports episode of care — where the patient is in the treatment and healing timeline — and it has to match the visit type, not simply restate the same code used at the first visit. Using a Colles' fracture of the right radius as a worked example, verified against the FY2026 ICD-10-CM code set:
| Code | 7th character | Episode of care |
|---|---|---|
S52.531A | A | Initial encounter, closed fracture — the visit where active treatment is rendered |
S52.531D | D | Subsequent encounter, routine healing — the standard follow-up visit code for most of the global period |
S52.531G | G | Subsequent encounter, delayed healing |
S52.531K | K | Subsequent encounter, nonunion |
S52.531P | P | Subsequent encounter, malunion |
S52.531S | S | Sequela — a late effect of the fracture, reported after active and healing treatment has concluded |
Fracture codes that distinguish open-fracture severity by the Gustilo classification carry additional 7th characters for that branch (initial encounter for open fracture, and its own subsequent-routine/delayed/nonunion/malunion characters), which is why some fracture families show more than the six characters above — check the specific code's full 7th-character set rather than assuming every fracture code follows the exact same six-character pattern.
The denial mechanism is mechanical, not clinical: a payer's claims-processing system cross-checks the 7th character against the visit type and the date pattern relative to the initial encounter, and a mismatch — most commonly, billing the initial-encounter "A" character on what is actually a routine follow-up visit inside the global window — stops the claim before medical necessity is ever evaluated. This is an easy error to make when a template or a copy-forward note carries the original diagnosis code into every subsequent visit without updating the 7th character to reflect the encounter type actually being billed. Build a check into your coding workflow that flags any fracture-diagnosis claim using an "A" character on a date that isn't the documented first treatment date.

Frequently asked questions
How do we know if a fracture code carries a 10-day or a 90-day global period?
Check the global period assigned to the specific CPT code billed, not the injury itself. As a general pattern, closed treatment without manipulation typically falls in the shorter, 10-day global family, while treatment requiring manipulation, percutaneous skeletal fixation, or open reduction internal fixation typically falls in the 90-day family. The same fracture can be billed under codes with different global assignments depending on how it was actually treated, so confirm the exact global days for your billed code in the CMS Physician Fee Schedule Look-Up Tool rather than assuming from the fracture type.
Can we bill an X-ray taken during a fracture's global period separately?
Yes. The fracture global package covers routine follow-up visits and the first cast or splint application, but it does not include imaging performed to assess healing, casting and splinting supplies beyond the first application, or DME such as a walking boot. Bill the radiology code for the follow-up film and the appropriate supply codes for any re-casting or bracing separately from the fracture treatment code itself; bundling those into the global fee gives away margin silently, because an underbilled supply or imaging line never generates a denial the way a rejected claim does.
What ICD-10 character do we use for a fracture follow-up visit inside the global period?
It depends on the healing status documented at that visit, not the calendar date. The 7th character tracks episode of care: A reports the initial encounter for a closed fracture, D reports a subsequent encounter with routine healing, G reports subsequent care with delayed healing, K reports nonunion, P reports malunion, and S reports a sequela. Billing the initial-encounter A character on a routine follow-up inside the global window, instead of the subsequent D character, is a common cause of a claim rejecting on an episode-of-care mismatch before medical necessity is ever evaluated.
