The pandemic did not simply interrupt medical billing; it rewrote the operating assumptions underneath it. Virtual visits became a standing service line, patient insurance status started changing month to month, payer policies were revised faster than in-house teams could track, and practices that had never considered outsourcing discovered how fragile a one-person billing desk really was. Several years on, those shifts are permanent features of the revenue cycle rather than emergency measures.
This guide gathers everything a practice needs to understand about medical billing services in a post-COVID environment: what changed for good, which compliance obligations never went away, how pre-authorization and electronic claims work now, how denial management has to be structured, and how to judge whether the practice is prepared. Each section is written for the administrator who owns the numbers, not the policy specialist.
What the pandemic changed for good
Four operational shifts outlasted the public health emergency and now define ordinary billing. First, telehealth is a routine visit type with its own place-of-service, consent, and documentation requirements, and payers apply different cost-sharing rules to it than to in-person care. Second, eligibility churn is higher: patients move between employer plans, marketplace plans, and Medicaid more often, so coverage verified at scheduling may be wrong by the visit date. Third, payer policy updates arrive continuously through portals and bulletins rather than in an annual cycle. Fourth, patient financial responsibility is a larger share of practice revenue, which turns collections into a front-desk discipline rather than a back-office afterthought.
| Area | Pre-pandemic norm | Current norm |
|---|---|---|
| Visit types | In-person, occasional phone follow-up | In-person plus video and audio-only visits billed as distinct services |
| Eligibility | Checked at first visit, rarely rechecked | Verified before every encounter, including virtual ones |
| Payer rules | Annual fee-schedule and policy cycle | Rolling policy bulletins, portal notices, and mid-year coverage edits |
| Staffing model | Single in-house biller or small team | Hybrid teams, remote billers, and outsourced billing partners |
A practice still running on the left-hand column sees it in the denial report first.
Compliance obligations that never went away
Emergency flexibilities came and went, but the underlying compliance framework was constant throughout and still governs every claim. The practical obligations fall into three groups.
Keeping coding current
Diagnosis and procedure code sets are updated on a fixed annual rhythm, with respiratory, infectious-disease, and vaccine-related codes among the most frequently revised. A biller who still codes an acute upper respiratory infection to the general category (J06) when the documentation supports the unspecified site code (J06.9) is choosing the less specific option and inviting a medical-necessity query. Certified coders who work from the current code set, supported by professional medical coding services when volume spikes, are the first line of defence.
Privacy, documentation, and workplace rules
HIPAA obligations apply equally to remote billers, video platforms, and patient portals, so every vendor in the chain needs a business associate agreement and documented safeguards. Occupational safety rules and state licensure requirements also affect which services can be billed and by whom.
Audit readiness
Payers and federal programme integrity contractors review pandemic-era claims retrospectively, and the practices that fare best are those with documentation linked to every claim line. A periodic medical billing audit and consultation surfaces gaps before a payer does. The wider rationale is set out in why getting healthcare billing compliance right protects your practice.
Pre-authorization, eligibility, and electronic claims
Electronic claim submission is now the baseline rather than a best practice. Paper and portal-only submissions cost more per claim, take longer to adjudicate, and cannot be scrubbed automatically. Clearinghouse edits catch missing identifiers, invalid code combinations, and payer-specific formatting before the claim leaves the building, which is where most first-pass rejections are prevented.
Pre-authorization is the second gate. Payers require advance approval for a growing list of procedures, imaging studies, injectable drugs, and specialist referrals, and an approval is tied to specific procedure codes, dates, and units. When the service delivered differs from the service authorised, the claim denies even though approval was obtained. The fix is procedural: the authorisation number, approved codes, and expiry date travel with the appointment, and the biller reconciles them against the charge before submission. Eligibility verification belongs in the same workflow, run before every visit rather than at intake.
Visit types that grew during the pandemic bring their own rules. Advance care planning conversations, for example, are billable services with time and documentation thresholds, explained in the practical guide to getting paid for advance care planning. New patient volume has also returned, and the documentation needed to support each visit level is covered in best practices for billing new patient office visits.
Denial management and the readiness checklist
Denial management is where post-pandemic billing succeeds or fails. Payers reprocess, recoup, and deny in patterns that only show up when denials are logged by reason code, payer, and provider and then reviewed weekly. The discipline has three parts: prevent what can be prevented at scrubbing, appeal what is worth appealing within the payer's deadline, and feed every root cause back into templates, training, and front-desk scripts. A practice that only works denials when cash gets tight is subsidising its payers.
Use this checklist to judge whether the practice is genuinely prepared:
- Eligibility is verified before every encounter, including virtual visits, and virtual cost-sharing is collected at the right rate.
- Claims are scrubbed and submitted electronically within a day of service, with rejections worked the same day.
- Denials are logged by reason and payer, reviewed weekly, and appealed within the filing window.
- Telehealth templates carry the correct place-of-service and consent documentation by default.
- Coding staff hold current certifications and work from the current code set.
- Every vendor touching patient data has a signed business associate agreement.
- Monthly reporting covers first-pass acceptance, days in accounts receivable, net collections, and patient balances over ninety days.
Any item that cannot be ticked with evidence is the next project.
What this means for medical billing practices
The practices that came through the pandemic with healthy cash flow were not the ones with the most patients; they were the ones whose billing operation could absorb rule changes without dropping claims. That resilience is a design choice. It comes from electronic workflows, weekly denial review, current coding, and enough capacity that a single absence does not stall cash. Many practices reach it fastest by partnering with professional medical billing services rather than rebuilding in-house. 24/7 Medical Billing Services has been managing revenue cycles since 2005 and is HIPAA- and SOC 2-compliant. Clients see claims scrubbed and filed within 24 hours, a ~99% first-pass clean-claim rate, and days in A/R under 25, with a dedicated account manager and a free 360° reporting dashboard to keep the numbers visible.
Frequently asked questions
What changed permanently in medical billing after COVID?
Telehealth became a standing visit type with its own documentation and cost-sharing rules, eligibility now has to be verified before every encounter because coverage changes often, payer policy updates arrive continuously instead of annually, and patient balances make up a larger share of revenue. Billing operations built for the older, slower cycle generate avoidable denials.
Do pandemic-era billing flexibilities still apply?
Most emergency waivers have ended or been replaced by permanent policy, and the rules differ by payer and by service. The safe approach is to treat every telehealth, audio-only, and remote-monitoring claim as governed by current written payer policy rather than by anything that was permitted during the emergency period.
How often should eligibility be checked now?
Before every visit, including virtual ones. Patients move between employer coverage, marketplace plans, and Medicaid more frequently than they did, and a plan verified at intake may be terminated or changed by the appointment date. Real-time verification the day before the visit catches most problems while the patient can still be contacted.
Why do authorised services still get denied?
An authorisation approves specific procedure codes, units, and dates. When the service performed differs from what was approved, or the authorisation has expired, the claim denies despite the approval. Reconciling the authorisation against the actual charge before submission, and updating it when the plan of care changes, prevents most of these denials.
