RTM program · Orthopedic surgery

Knee and hip replacement recovery

Adherence and ambulation in the first three weeks tell you who is falling behind.

This is the cleanest short-duration RTM episode in orthopedics, and the 2026 short-duration device code makes the first two post-operative weeks independently billable. The patients who fall behind on their protocol in the first three weeks are the ones who end up back in clinic, and adherence and ambulation are visible days before anyone reports a problem. A program that only exists to watch those two things for 21 days is a good program.

What gets measured, from where, and why it earns its place

Every source is tagged at ingest as billable or context-only. Context-only data is clinically valuable and never enters a device-supply line.

Exercise adherence
Session logging with prescribed protocol
Post-operative protocols are specific and time-boxed. Adherence is measurable against a known plan.
Ambulation
Passive step count
Progression from assisted to independent walking, without asking the patient to estimate.
Pain and swelling
Daily short form with optional photo
Swelling photographs are also the earliest wound-complication signal you will get.

Thresholds, and who has to do something about them

Red marks a same-day or immediate pathway. Amber marks a review within the stated window. Each one is assigned to a named clinician with a response clock, not to a queue.

These are configurable program defaults, not clinical recommendations. The treating clinician sets every threshold for their own panel and owns the response it triggers. Nothing here is medical advice.

How the month actually runs

Enroll pre-operatively so the app is installed before anesthesia.
Setup billed once under 98975, ideally at the pre-op visit.
Daily adherence and ambulation for 21 days, then taper.
Bill 98985 for the short episode or 98977 if it runs 16 or more days. Management time by actual minutes.

The rules that break programs

One billing clinician per 30-day episode. RPM and RTM are not additive in the same calendar month. Duration codes are mutually exclusive. Management time requires at least one real-time interactive communication. Medical necessity precedes enrollment.

Sponsor view

If you are a manufacturer looking at this condition

Limited pharmaceutical relevance beyond non-opioid perioperative analgesia programs that need functional recovery endpoints and opioid-sparing evidence. Device manufacturers and bundled payment participants are the more natural sponsors here.

Read this before you fund anything

Sponsor-funded monitoring that produces billable revenue for prescribers is remuneration to referral sources under the federal Anti-Kickback Statute. The structures that survive scrutiny keep the sponsor's data interest and the provider's billing interest completely separate. The three structures we will build, and the one we will not.

Questions

Knee and hip replacement recovery monitoring, answered directly

Can we bill RTM during a global surgical period?
Post-operative care included in the global package is not separately billable. Whether your RTM program is distinct from included care depends on the specifics. Confirm before you build volume assumptions on it, because this is where orthopedic RTM programs most often break.
