Clinical Context
A 67-year-old patient with chronic low back pain is seen for an initial home health physical therapy evaluation after discharge from the hospital. The therapist performs a single focused visit to teach a home exercise program, provides education on activity modification, and documents recommendations for outpatient follow-up. No ongoing skilled therapy is scheduled because the patient is referred to an outpatient clinic and instructed to continue the home program. Care is billed as a single encounter indicating ongoing care is not indicated.
Typical clinical workflow:
-
Referral received from hospital discharge planner or primary care provider.
-
Initial assessment and one-on-one instruction in the home setting, with documentation of findings, interventions delivered, patient/caregiver education, and a plan recommending referral to outpatient services.
-
Billing uses the HCPCS Level II code M1144 to indicate that ongoing skilled care is not indicated and only 1–2 visits were provided (home program only or consultation).
-
Clinical documentation includes reason for limited visits, functional status, home program details, and referral disposition for audit support.
Typical site of service: home health / patient home or an ambulatory clinic when visit is a single consultation and further care is directed elsewhere.
Service type: short-term consultation / single-encounter skilled therapy visit (home program only, consult or referral only).

|---|
22 | Increased procedural services | Use when work required is substantially greater than typically required for the service, documented with justification and time/effort details. |
| 23 | Unusual anesthesia | Use when an anesthesia service was required for a procedure that usually does not require anesthesia; rarely applicable to consult-only home visits.
| 52 | Reduced services | Use when the service performed is partially reduced or eliminated at the physician's discretion — e.g., abbreviated visit vs. full evaluation.
| 53 | Discontinued procedure | Use when the planned service was started but terminated due to patient condition or safety concerns.
| 54 | Surgical care only | Use when the billing provider is responsible only for the surgical portion; not commonly applied to M1144 but included for consults around procedures.

| 56 | Preoperative management only | Use when only preoperative evaluation is provided and ongoing care is not indicated.
| 62 | Two surgeons | Use when two surgeons work together as primary surgeons on a procedure; seldom used with consult-only home visits.
| AS | Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery | Use when an advanced practice clinician serves as an assistant at surgery; not typical but included for completeness.
| CO | Managed care plan | Use to indicate services billed under a specific managed care plan when required by payer reporting rules.
| CQ | Service furnished by an assistant surgeon (non-physician) | Use when a non-physician assistant provides surgical assistance; rarely applicable to M1144.
| FX | Single limb/segment | Use in orthopedics to indicate single-level/limb fixation; uncommon for consult-only visits.
| FY | Multiple limbs/segments | Use in orthopedics when multiple levels are involved; uncommon for this code.
| QK | Medical direction of two, three, or four technicians | Use when the physician medically directs multiple assistants/techs during a procedure; unlikely for a single consultation.
