The medical side of a workers’ compensation case runs on paperwork. Your treating physician provides the care. But the forms your doctor files, the guidelines your treatment must follow, and the variance process that applies when treatment falls outside those guidelines determine whether you receive the care you need without delay. When these systems work as intended, treatment flows smoothly. When they break down — because a form is filed late, a guideline is misapplied, or a variance is denied — the injured worker is the one who suffers.
This article explains the three systems that govern the medical treatment process in New York workers’ compensation: the Medical Treatment Guidelines, the variance request procedure, and the Form C-4 reporting requirement.
The Medical Treatment Guidelines
The Workers’ Compensation Board maintains Medical Treatment Guidelines that establish evidence-based protocols for treating common workplace injuries. The guidelines are organized by body part and diagnosis. They cover injuries to the back, neck, shoulder, knee, hip, wrist, hand, elbow, ankle, and foot, as well as specific conditions including carpal tunnel syndrome, complex regional pain syndrome, and mid and low back injuries.
Each guideline specifies what treatments are considered appropriate at each stage of recovery. For a back injury, for example, the guideline may specify that initial treatment should include rest, medication, and physical therapy, with imaging studies ordered if symptoms do not improve within a certain period, and surgical consultation recommended only after conservative treatment has been tried for a defined duration. The guidelines create a standardized framework that applies to all workers’ compensation cases involving that type of injury.
The guidelines serve a practical purpose for injured workers: if your treating physician recommends treatment that falls within the applicable guideline, the insurance carrier must authorize and pay for that treatment without requiring prior approval. This eliminates one layer of potential delay. The carrier cannot refuse to pay for treatment that the Board’s own guidelines identify as appropriate.
The guidelines are not suggestions. They carry the force of regulation. Both the treating physician and the insurance carrier are expected to follow them. When they disagree about whether a particular treatment falls within the guidelines, the dispute is resolved through the variance process or at a hearing before a Workers’ Compensation Law Judge.
When your doctor recommends treatment outside the guidelines
The guidelines are designed to cover the most common treatment scenarios, but not every patient fits neatly into a standard protocol. Your injury may be more complex than the guideline anticipates. You may have a pre-existing condition that affects how you respond to standard treatment. The recommended number of physical therapy sessions may not be enough for your particular recovery. Your doctor may believe a procedure is medically necessary even though the guideline does not include it for your diagnosis.
In these situations, your treating physician must request a variance from the Medical Treatment Guidelines. The variance process is the mechanism by which a doctor explains to the Board why treatment outside the standard protocol is medically necessary for a specific patient.
The Form MG-2 variance request
To request a variance, the treating physician files a Form MG-2 with the Workers’ Compensation Board. The form requires the physician to identify the specific treatment being requested, explain why it falls outside the applicable guideline, and provide a medical justification for why the treatment is necessary for this particular patient.
The quality of the MG-2 submission directly affects whether the variance is approved. A variance request that says “patient needs more physical therapy” without further explanation is likely to be denied. A request that explains that the patient has a complex multi-level disc herniation with radiculopathy, that the standard course of physical therapy produced measurable but incomplete improvement in range of motion and pain scores, and that an additional twelve sessions are expected to bring the patient to a level where surgical intervention can be avoided — that request has a substantially better chance of approval.
The insurance carrier has the opportunity to respond to the variance request, and the carrier may oppose it. If the carrier opposes the request, the matter is referred to a Medical Director’s review or to a hearing before a Workers’ Compensation Law Judge. The variance process can take weeks, and during that time, the treatment in question may be delayed.
This delay is one of the most frustrating aspects of the system for injured workers. You and your doctor agree that a particular treatment is necessary. The guideline does not include it. The variance must be filed, reviewed, potentially opposed, and adjudicated before the treatment can proceed. Throughout this process, your condition may worsen or your recovery may stall. There is no shortcut around the variance process, but having a physician who writes thorough, specific MG-2 requests reduces the likelihood of denial and the duration of delay.
The Form C-4: your doctor’s report after every visit
The Form C-4 (Doctor’s Report of Injury/Illness) is the most important recurring form in your workers’ compensation case. Your treating physician must file a C-4 with the Workers’ Compensation Board after every visit. The form reports on your current condition, your diagnosis, the treatment provided, your disability status, and your work capacity.
The C-4 serves multiple purposes. It notifies the Board that your case is active and that you are continuing to receive treatment. It provides updated medical information that the Board uses to administer your claim. It documents the ongoing development of your medical record. And it is the trigger for your wage replacement benefits — without a current C-4 on file, the Board may not process your benefit payments.
If your doctor fails to file the C-4, your benefits stop. This is not a theoretical risk. It happens regularly. A doctor’s office that is busy, understaffed, or unfamiliar with workers’ compensation requirements may fall behind on C-4 filings. When they do, the injured worker’s benefits are the first thing affected. Do not assume the C-4 has been filed. Ask your doctor’s office to confirm after every visit. If there is a pattern of late or missed filings, raise it directly with the doctor or consider transferring your care to a physician whose office handles the administrative requirements reliably.
The 45-day and 90-day visit requirements
While you are out of work and receiving wage replacement benefits, you must see your treating physician at least every 45 days. Each visit generates a C-4, which keeps your case active with the Board. If you go more than 45 days without a visit, your benefits may be suspended.
If your doctor recommends surgery and you decline — which is your right — the visit interval extends to 90 days. You are not penalized for declining surgery, but you must still maintain regular medical visits to demonstrate that your condition is being monitored and that you continue to require benefits.
Track these deadlines yourself. Mark the date of each visit on a calendar and count forward 45 days (or 90 days if applicable) to determine when your next visit must occur. Do not wait until the last day. Schedule your appointment with enough lead time to accommodate cancellations, rescheduling, or doctor’s office availability. A missed deadline is a missed deadline, regardless of the reason.
When the medical administration system breaks down
The medical treatment process in workers’ compensation involves multiple parties — the injured worker, the treating physician, the insurance carrier, and the Board — and failures can occur at any point. The doctor may not file the C-4 on time. The carrier may deny a treatment that falls within the guidelines. A variance request may be opposed without a clear medical basis. The Board may take weeks to process a routine filing.
When any of these failures occurs, the injured worker bears the consequences: delayed treatment, interrupted benefits, or a gap in the medical record that the carrier can later use to argue that the injury is improving. Staying on top of the administrative requirements — confirming C-4 filings, tracking visit deadlines, monitoring variance requests — is not optional. It is part of protecting your claim.
How Schwartzapfel Holbrook monitors the medical treatment process
At Schwartzapfel Holbrook, we monitor the medical treatment administration in every case. That means tracking C-4 filings to ensure they are submitted after each visit, reviewing the treating physician’s independent clinical findings for thoroughness, monitoring variance requests and intervening when they are opposed without justification, and ensuring the 45-day visit requirement is met so benefits are not interrupted.
When treatment is delayed because of a variance denial or a carrier dispute, we prepare the case for a hearing. The treating physician’s documentation of medical necessity is the evidence the Workers’ Compensation Law Judge relies on. Our role is to ensure that documentation is complete, specific, and presented effectively.
