Hand procedure
About 20527: Collagenase injection for Dupuytren cord
Report this service for injecting collagenase into a palmar fascial cord to treat Dupuytren contracture, typically as part of a staged treatment plan.
A clinician injects collagenase into a palpable cord of thickened palmar fascia causing Dupuytren contracture. Hand surgeons and other clinicians who treat hand disorders commonly perform the injection in an office or outpatient setting. The enzyme weakens the targeted cord; a separate manipulation may be performed at a later visit to help extend the affected finger. Document the cord and hand treated, the contracture findings, and the injection performed.
Report 20527 for the injection service, not for the later manipulation. When collagenase is supplied and separately reportable, the drug is reported with its applicable drug code and units. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. For multiple procedures in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment is restricted, and co-surgery and team-surgery payment are not permitted.

Where does this rate apply?
Modesto is a Medicare payment area. Our Census mapping connects it to 33 cities and communities in California, including the examples shown here.
Some communities span more than one payment area. Follow a city link to compare all of its mapped areas, or check the service-location ZIP above for an address-level starting point.
Why are the office and facility amounts different?
For 20527 in Modesto, the physician’s office rate is $97.09 and the facility-setting rate is $57.92: a difference of $39.17.
The calculation uses a different practice-expense RVU for each setting. Both amounts here are physician fee-schedule amounts. The facility figure does not include a hospital’s separate charges, so this comparison does not tell you the total cost of receiving care in each setting.

20527 billing questions
When should 20527 be chosen instead of a palmar fasciectomy code?
Use 20527 for enzyme injection into a palmar fascial cord. A fasciectomy code describes surgical removal of diseased fascia, not injection treatment.
Is the post-injection finger manipulation included in 20527?
No. The manipulation is a separate service, commonly reported with 26341 when performed after collagenase injection; it is typically done at a later visit.
Can the collagenase drug be reported separately?
When the drug is separately reportable, report it with the applicable drug code, such as J0775, using units based on the amount administered. The 20527 service represents the injection procedure.
What documentation supports reporting 20527?
Document the Dupuytren contracture, the targeted palmar fascial cord and hand, and the collagenase injection performed. Record the drug and amount administered when needed to support separate drug reporting.
How is 20527 reported when both hands are treated?
CMS lists bilateral reporting with modifier 50, paid at 150%. Document the injection on each side.
Does 20527 have a postoperative global period?
It has a 0-day global period. Same-day preoperative and postoperative care is included.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
