What are the Minnesota workers' comp opioid prescribing limits?

When the limit can be longer

• Long-term contract path

  Daily opioid treatment for at least 90 days requires a written treatment contract, regular follow-up, urine drug testing, and prescription-monitoring review.

  Minn. R. 5221.6110

The specific counts

• Acute phase (first 4 weeks)

  Maximum 2 weeks of medication per prescription

  Applies to oral opioids prescribed within the first four weeks after the injury.

  Minn. R. 5221.6105, subp. 3

• After 4 weeks

  Maximum 1 month of medication per prescription

  Applies when oral opioids are prescribed more than four weeks after the date of injury.

  Minn. R. 5221.6105, subp. 3

• Long-term daily use

  Daily for at least 90 days requires a written contract and monitoring

  Long-term treatment requires a written treatment contract, regular follow-up visits, urine drug testing, and prescription-monitoring review.

  Minn. R. 5221.6110

• High-dose review

  More than 120 MME per day

  Enhanced monitoring includes follow-up at least every three months, urine drug testing at least twice per year, and prescription-history review at every visit.

  Minn. R. 5221.6110, subp. 8

If this care was denied or stuck

If the insurer denies authorization or payment in writing, the dispute is a Medical Request to DLI under Minn. Stat. § 176.106, not a Claim Petition, so long as primary liability for the injury is admitted. The denial must state why the proposed care is not supported and that departures may apply. Minn. R. 5221.6050, subps. 7.B and 7.C.

Prior notification, silence, and the 45-day IME window

• Seven days to answer

  For departures, inpatient surgery, some chronic programs, and certain equipment, the treating provider must notify the insurer at least seven working days before the care starts. The rule then gives the insurer seven working days to approve, deny in writing, ask for more records, require a second surgical opinion, or schedule an employer IME. For non-emergency surgery, the statute is tighter: the insurer must answer in writing within seven calendar days.

  Minn. R. 5221.6050, subp. 9.A and 9.C; Minn. Stat. § 176.135, subd. 1a(a)

• Complete silence counts as authorization

  If the provider hears nothing for seven working days after proper notice, authorization is deemed given. If the insurer affirmatively authorizes care, it generally may not later refuse to pay that authorized treatment.

  Minn. R. 5221.6050, subp. 9.C, items (1) and (2)

• An IME or second-opinion request is not a denial

  A second-opinion request, an employer IME under Minn. Stat. § 176.155, or a demand for more records is not a denial. Non-emergency surgery usually waits while those steps run. Workers' comp is primary for work-injury treatment under Minn. Stat. § 176.135, subd. 1, so group health is not a practical backup. Many providers will not schedule major care until someone with a comp claim number accepts financial responsibility. That is the gap: no surgery, no health-plan bill, and no denial letter to file on.

  Minn. R. 5221.6050, subp. 9.C, items (5), (6), and (7); Minn. Stat. § 176.135, subd. 1

• Forty-five days after an employer IME on surgery

  When prior notification of non-emergency surgery is required and the insurer timely requests an employer examination, the surgery may not be performed pending that exam. After 45 days from the insurer's exam request, the surgeon may elect to proceed, subject to a later compensability decision. That is when the stall is usually ripe to file a Medical Request. DLI can decide the fight at a conference if the amount in dispute is $7,500 or less; a larger surgery dispute can be certified to OAH.

  Minn. R. 5221.6050, subp. 9.C, item (6); Minn. Stat. § 176.106, subds. 1 and 3

• When there is an actual denial

  A written denial triggers the medical dispute path: request the insurer's internal review, or file a Medical Request with DLI attaching the provider's notice and the insurer's response. That route applies when liability for the injury itself is not in dispute. A primary liability fight still belongs in a Claim Petition at OAH.

  Minn. R. 5221.6050, subps. 7.C and 9.C, item (3); Minn. Stat. § 176.106
