Summary & Overview
HCPCS M1048: Oswestry Disability Index Preoperative and 3-Month Postoperative Assessment
HCPCS Level II code M1048 denotes collection of functional status using the Oswestry Disability Index (ODI version 2.1a) with documentation of a preoperative score obtained within three months before surgery and a postoperative score obtained at three months (6–20 weeks) after surgery. This code captures standardized patient-reported outcome measurement for patients undergoing spine or related musculoskeletal procedures and supports tracking functional recovery over the perioperative period. Nationally, standardized outcome measurement is increasingly emphasized for quality reporting, care coordination, and value-based payment models, making clear coding for these measures relevant to providers and payers alike.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context, common settings where the service is delivered, and what the code represents for documentation and billing. The publication provides benchmarks and policy context where available, summarizes coverage considerations reported by major payers, and outlines operational implications for collecting and reporting patient-reported outcomes in perioperative care. Data not available in the input is noted when specific payer policies, modifiers, taxonomies, ICD-10 pairings, or related codes are not provided.
Billing Code Overview
HCPCS Level II code M1048 describes a functional status measurement using the Oswestry Disability Index (ODI version 2.1a) patient-reported outcome tool. The service requires a score obtained within three months preoperatively and again at three months postoperatively (defined as 6 to 20 weeks post-op).
-
Service type: Patient-reported outcome measurement for functional status related to spine or musculoskeletal surgical care
-
Typical site of service: Ambulatory clinic or preoperative/postoperative outpatient visit
Clinical & Coding Specifications
Clinical Context
A 55-year-old patient with chronic low back pain due to lumbar disc degeneration is scheduled for elective lumbar fusion. Preoperative evaluation includes collection of patient-reported outcomes using the Oswestry Disability Index (ODI version 2.1a). The instrument is administered in clinic within three months prior to surgery to establish baseline functional status. Postoperative follow-up at three months (defined as 6 to 20 weeks post-op) includes repeat ODI administration to quantify change in disability and to inform recovery planning. The workflow typically involves nursing staff or a medical assistant providing the ODI questionnaire (paper or electronic), entering the score into the electronic health record, and a clinician reviewing results during the preoperative visit and the three-month postoperative visit. The service represented by M1048 documents that a scored ODI was obtained at both time points and recorded in the medical record for use in outcomes tracking and surgical care decisions.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
25 | Significant, separately identifiable evaluation and management service by the same physician on the same day of the procedure | Use when an E/M visit is performed on the same day as collection or review of the ODI and is separately documented |
