What 98928 covers

This service represents osteopathic manipulative treatment directed at somatic dysfunction in seven or eight body regions. A physician, commonly a doctor of osteopathic medicine, uses hands-on techniques to treat the affected regions. The regions counted are the head, cervical, thoracic, lumbar, sacral, pelvic, lower-extremity, upper-extremity, and rib-cage areas. Treatment may occur in an office or facility setting.

Select this level based on the distinct regions actually treated, not simply the regions examined or noted as dysfunctional. The record should identify the treated regions and support that manipulation was performed. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. Modifier 50 is inappropriate for bilateral adjustment. Assistant-at-surgery payment requires documentation of medical necessity; co-surgeons and team surgery are not permitted.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

98928 billing questions

How do I choose this code instead of 98927 or 98929?

Count the distinct body regions that received osteopathic manipulation. Use 98928 for seven or eight treated regions; 98927 represents five or six, and 98929 represents nine or ten.

Do regions that were only examined count toward the level?

No. The level is based on regions treated with manipulation, so documentation should distinguish those regions from areas that were only evaluated.

Can I append modifier 50 for treatment on both sides?

No. CMS identifies bilateral adjustment as inappropriate for this code.

What is included in the 0-day global period?

Same-day preoperative and postoperative care is included in the service under CMS's 0-day global-period rule.

Can an assistant or another surgeon be reported?

Assistant-at-surgery payment is limited to cases with documented medical necessity. Co-surgeons and team surgery are not permitted.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
