Most medical billing companies serve all US Healthcare Specialties.

Which means, in practice, they serve none of them well.

When a billing company handles 40 different specialties with the same generalist workflow — the same CPT code lookup, the same authorization submission process, the same denial management protocol — the result is billing that’s functional but not optimized. Claims go out. Payments come in. The practice never knows what’s missing.

Malakos Healthcare Solutions made a different decision. We serve eight specialties. Not forty. Eight. And we go deep into each one — building the specific coding standards, authorization workflows, documentation requirements, and denial management protocols that each specialty’s billing environment demands.

This post covers every specialty Malakos Healthcare Solutions serves — what makes billing in that specialty uniquely complex, what most practices are getting wrong, and exactly how Malakos helps.

1. Pain Management Billing Services

Why Pain Management Billing Is Different

Interventional pain management sits at the intersection of the most complex billing rules in outpatient medicine. High per-claim values. Intensive prior authorization requirements. Approach-specific procedure coding. Imaging guidance documentation standards. Multiple procedure reductions that must be reconciled against contracted rates. Medical necessity scrutiny on virtually every interventional procedure.

A single missed RFA authorization, a defaulted ESI approach code, or an unverified imaging guidance billing can cost $1,500–$30,000 in delayed or permanently lost revenue on a single claim.

What Most Pain Management Practices Get Wrong

  • ESI approach code errors: Billing 62323 (interlaminar) when the procedure note documents a transforaminal approach that should be 64483 — on every transforaminal ESI, every day
  • Imaging guidance not captured: Never billing CPT 77003 or 76942 on qualifying procedures, or billing without verifying permanent image record and interpretation report
  • RFA authorization failures: Submitting authorization without the complete diagnostic MBB documentation package — two prior positive blocks, specific pain relief percentages, payer-specific thresholds (50% vs. 80%)
  • SCS permanent implant denied: Assuming trial authorization covers the permanent implant — two separate authorizations, two separate workflows
  • Multiple procedure reduction underpayments: Payer applying 60% when the contract says 50% — written off as a standard contractual adjustment, never disputed

How Malakos Helps

Every interventional procedure claim is reviewed against the procedure note before CPT code assignment — approach verified, imaging guidance documentation confirmed, add-on codes captured for every additional level. RFA authorizations go out with a complete MBB documentation package assembled from the chart. SCS authorizations are tracked as two independent workflows. Payment posting includes contracted rate reconciliation on every ERA — underpayments are flagged and disputed within five business days.

Result for pain management practices: Clean claim rates above 93%. RFA first-submission authorization approval rates above 80%. Underpayment recovery at every billing cycle. Annual revenue improvements of $180,000–$340,000 for solo and two-physician practices.

2. Physical Therapy Billing Services

Why PT Billing Is Different

Physical therapy billing is time-based, modifier-dependent, and authorization-intensive in ways that produce predictable, compounding errors in practices without specialty-specific billing expertise.

Timed services (97110, 97112, 97140, 97530) must be billed in 15-minute units based on documented direct provider contact time per service — not session duration. The 8-minute rule governs unit calculation for combined timed services in a single visit. CQ and CO modifiers are required on Medicare claims when a PTA or COTA renders any portion of care. KX modifier must be applied when Medicare therapy thresholds are exceeded. Progress Report documentation must appear at defined intervals or Medicare claims become audit-vulnerable.

Every one of these rules has a specific, measurable failure mode in practices that don’t manage them systematically.

What Most PT Practices Get Wrong

  • 8-minute rule errors: Billing by session duration rather than per-service direct time — systematic unit count errors across every patient visit, every day
  • CQ modifier non-compliance: Missing CQ on Medicare claims for PTA-rendered services — a compliance violation that creates retroactive recoupment exposure
  • KX modifier not tracked: Medicare therapy threshold reached, KX not applied — automatic Medicare denial
  • Prior authorization expiration: Authorizations lapse between sessions without tracking — services rendered without confirmed coverage
  • Evaluation complexity undercoded: 97161 (low complexity) billed for every evaluation regardless of clinical presentation — $40–$65 missed per qualifying evaluation
  • Underpayment acceptance: Multiple procedure reductions applied above contracted rates — accepted without dispute at payment posting

How Malakos Helps

Per-service direct time is verified against billed unit counts before every claim is submitted. CQ modifier is applied at the rendering provider level — tracked per session, per provider, per payer. KX threshold is monitored per Medicare patient per calendar year. Authorization visit counts and expiration dates are tracked per patient with renewal triggers set before the authorization is exhausted. Evaluation complexity is coded based on documented clinical presentation — not defaulted to 97161. Every ERA is reconciled against contracted rates.

Result for PT practices: 8-minute rule unit accuracy on every claim. Zero CQ compliance violations. KX-related denials eliminated. Authorization expiration denials reduced to near zero. Annual revenue improvements of $90,000–$180,000 for two-therapist practices.

3. Chiropractic Billing Services (US Healthcare Specialties)

Why Chiropractic Billing Is Different

Chiropractic billing is governed by a relatively contained CPT code set — but the Medicare compliance requirements and documentation standards for that code set are among the most scrutinized in outpatient billing. Medicare covers chiropractic for active spinal conditions only. The line between active and maintenance care is a documentation question with significant compliance implications. CMT region count determines code selection. Modifier AT on Medicare CMT claims is required — and its presence or absence has compliance consequences in both directions.

What Most Chiropractic Practices Get Wrong

  • CMT undercoding: Billing 98940 (1–2 regions) when the procedure note documents 3-region treatment — $35–$55 per visit, compounding daily
  • Modifier AT misapplied: Missing AT on Medicare CMT claims (automatic denial) OR applying AT on maintenance care visits (compliance violation and recoupment risk)
  • Active vs. maintenance care documentation drift: Treatment notes shifting from functional improvement to symptom management without billing acknowledgment — Medicare compliance exposure on every long-term patient
  • Therapeutic modality documentation insufficient: “E-stim applied” without separate clinical rationale — bundling denials and audit exposure
  • PI billing not maximized: Billing CMT-only on personal injury cases when comprehensive evaluation codes are separately billable
  • AR denials unworked: Hard denials sitting past appeal windows — recoverable revenue aging into permanent write-offs

How Malakos Helps

CMT code assignment is made after region count verification from the procedure note — not from the charge ticket default. Modifier AT is applied after confirming active treatment documentation — functional improvement indicators, objective outcome measures, skilled care rationale — before Medicare CMT claims are submitted. Modality documentation is reviewed for separate clinical rationale before billing. PI charge capture includes evaluation code prompts at intake. Denied claims are pursued by value — high-dollar denials receive active follow-up before low-dollar claims.

Result for chiropractic practices: CMT coding accuracy across all providers. Zero AT compliance violations. Modality bundling denials reduced. Annual revenue improvements of $90,000–$165,000 for multi-provider chiropractic groups.

4. Integrative Medicine Billing Services

Why Integrative Medicine Billing Is Different

Integrative medicine practices deliver multiple distinct, separately billable services to the same patient on the same date — an office visit, acupuncture, medical nutrition therapy, health behavior intervention, IV therapy. When these services are billed correctly, every service generates its own reimbursement.

When they’re billed without understanding same-day service combination rules, payers bundle secondary services into the primary service payment and reimburse the others at zero. No denial. No alert. Just a bundled payment that looks complete — while the practice collected for one service when it delivered four.

What Most Integrative Medicine Practices Get Wrong

  • Modifier 25 missing on same-day combinations: E/M bundled into therapy payment on every combination visit — $72,000–$120,000 per year in missed E/M revenue
  • Acupuncture billed to Medicare for non-CLBP diagnoses: Medicare covers acupuncture only for chronic low back pain — non-CLBP acupuncture to Medicare is an automatic denial (and an ABN compliance issue)
  • MNT never billed for Medicare patients: Medical nutrition therapy is a covered Medicare benefit for diabetes and CKD patients — never billed in most integrative practices
  • Health behavior intervention codes never used: CPT 96156/96158/96159 — delivered routinely, never billed
  • IV therapy billing incomplete: Add-on hour codes (96366) not billed on 90+ minute infusions; unlisted procedure codes used instead of specific infusion codes
  • AWV combination billing missed: Same-day problem addressed during AWV — separate E/M with Modifier 25 never billed

How Malakos Helps

Every date of service is reviewed for same-day combination billing before submission — Modifier 25 applied on every qualifying E/M code alongside a therapeutic service. Medicare acupuncture claims are verified against CLBP-covered ICD-10 codes before submission. MNT and health behavior intervention codes are built into charge capture workflows. IV therapy is billed with correct infusion codes, correct add-on hour codes, and ABN management for Medicare patients. AWV combination billing is captured on every qualifying encounter.

Result for integrative medicine practices: Modifier 25 capture rates above 95% on qualifying combination visits. MNT revenue captured from a previously unbilled service category. Annual revenue improvements of $130,000–$220,000 for multi-provider integrative clinics.

5. Family Practice and General Practice Billing Services

Why Family Medicine Billing Is Different

Family medicine billing looks straightforward on the surface — office visits, preventive care, some in-office procedures. What makes it financially complex is the breadth of what correctly-billed family medicine generates that most practices never capture: Chronic Care Management codes for every qualifying Medicare patient, Transitional Care Management for every post-hospitalization follow-up, Remote Patient Monitoring for chronic disease patients, Annual Wellness Visit combination billing, and E/M optimization under 2021 AMA guidelines.

The gap between what a correctly-billed family medicine practice should collect and what most family medicine practices actually collect typically runs $150,000–$300,000 per year for a two-physician group.

What Most Family Medicine Practices Get Wrong

  • CCM never billed: 150–200 qualifying Medicare patients, zero CCM claims — $75,000–$100,000 per year uncaptured
  • E/M undercoding: 90%+ of established patients at 99213 despite 2021 AMA guidelines supporting 99214 for most chronic disease management visits
  • AWV coded as standard E/M: G0438/G0439 used for 24% of AWV visits; 76% billed as 99213 — patient cost-sharing applied to a no-cost Medicare benefit
  • Modifier 25 missing: Same-day preventive and problem-focused visit — E/M bundled, secondary service paid at zero
  • TCM never billed: Post-hospitalization transition management performed routinely — $168–$237 per episode never captured
  • Telehealth POS errors: POS 11 on patient-home telehealth visits — documentation-to-claim mismatch creating audit exposure

How Malakos Helps

CCM infrastructure is built and activated within the first 60 days of engagement — qualifying patient identification, consent documentation, care plan development, monthly time-tracking workflow. E/M levels are coded under 2021 AMA guidelines — moderate complexity documented visits billed at 99214, not defaulted to 99213. AWV codes (G0438/G0439) applied correctly, with combination E/M billing for same-day problems addressed. Modifier 25 applied on every qualifying combination visit. TCM tracked from hospital discharge notification through office visit. Telehealth POS codes corrected per payer requirements.

Result for family medicine practices: CCM revenue activated — most practices see $4,000–$8,000 per month in new CCM collections within 90 days. E/M revenue increases without any change to clinical workflow. Annual revenue improvements of $150,000–$290,000 for two-physician groups.

6. Behavioral Health Billing Services (US Healthcare Specialties)

Why Behavioral Health Billing Is Different

Behavioral health billing is unique in that its two most expensive coding errors — psychotherapy time code errors and group therapy billing errors — produce no denial signal. The claim pays. It just pays at the wrong amount, or at 1/6 of the correct amount, because nobody corrected the billing approach.

Psychotherapy time codes must reflect documented therapy time — not scheduled session duration. Group therapy (CPT 90853) is billed per patient per session — not per group. PMHNP practices must use add-on codes (90833/90836/90838) for combined E/M and therapy sessions — not standalone codes. And MHPAEA parity violations — commercial payers imposing more restrictive visit limits on behavioral health than on comparable medical benefits — are legally challengeable but almost never challenged.

What Most Behavioral Health Practices Get Wrong

  • Psychotherapy codes billed to scheduled duration: 90834 for every 50-minute scheduled session regardless of documented time — compliance exposure on short sessions, missed revenue on 53+ minute sessions
  • Group therapy billed per session not per patient: 90853 × 1 unit for a group of 8 — collecting for 1 patient when 8 attended
  • Missing add-on codes: PMHNP billing E/M code alone when combined E/M and psychotherapy were delivered — 90833/90836/90838 never billed
  • Telehealth POS errors: POS 11 on patient-home sessions — documentation mismatch, active audit trigger
  • Medicare annual in-person requirement not tracked: Behavioral health telehealth without annual in-person visit documented — non-compliant Medicare claims
  • Parity violations never challenged: Commercial payer visit limits on behavioral health that don’t apply to comparable medical benefits — never formally disputed

How Malakos Helps

Session notes are reviewed for documented therapy start/stop times before psychotherapy codes are assigned — 90832, 90834, or 90837 based on documented minutes, not scheduled duration. Group therapy is billed per patient — one 90853 per attending patient per session. PMHNP add-on codes are applied when combined E/M and therapy documentation supports them. Telehealth claims use POS 10 for patient-home sessions with correct modifier application per payer. Medicare in-person visit dates tracked per patient. Parity violations identified and formally challenged when commercial payers impose more restrictive behavioral health benefit limits.

Result for behavioral health practices: Group therapy billing corrected — immediate revenue increase from 1/6 correct to full per-patient billing. Psychotherapy time codes reflect documented time — both compliance exposure eliminated and missed revenue captured. Annual revenue improvements of $80,000–$160,000 for solo and small group practices.

7. Nurse Practitioner Billing Services

Why NP Billing Is Different

Nurse practitioner billing involves a layer of complexity that no other specialty faces in the same way — the incident-to billing rules that allow qualifying visits to be billed under a supervising physician’s NPI at 100% of the Medicare rate rather than the NP’s own NPI at 85%.

Most NP practices either don’t know incident-to billing exists, or apply it incorrectly — billing all visits under the NP’s NPI even when incident-to eligibility is present, or applying incident-to to visits that don’t qualify (new problems, new patients, no physician on-site) and creating compliance exposure.

Beyond incident-to, NP practices with significant Medicare panels are missing Chronic Care Management revenue on a scale comparable to family medicine — and PMHNP practices are frequently underbilling on combined E/M and psychotherapy sessions.

What Most NP Practices Get Wrong

  • Incident-to billing never applied: All Medicare visits billed under NP’s NPI at 85% — even when supervising physician is present and incident-to eligibility is met — 15% left on every qualifying visit
  • Incident-to incorrectly applied: New problems billed incident-to when the physician hasn’t established a plan of care — compliance violation
  • CCM never billed: Qualifying Medicare patients managed for multiple chronic conditions — monthly care coordination work delivered, never billed
  • E/M undercoding: Same 99213 habit from physician billing applied to NP practice — same dollar gap
  • PMHNP add-on codes missing: Combined E/M and therapy sessions billed at E/M only — psychotherapy component uncaptured
  • AWV coded as standard E/M: Medicare AWV billed as office visit — patient cost-sharing applied to no-cost benefit
  • Telehealth compliance errors: POS 11 on patient-home sessions, missing Modifier 95 on commercial claims

How Malakos Helps

Incident-to eligibility is assessed per visit — appointments where the supervising physician is on-site and the patient is being seen for an established condition within the physician’s plan of care are billed under the physician NPI at 100%. Visits that don’t meet incident-to criteria are billed under the NP’s NPI at 85%. CCM infrastructure is built for qualifying Medicare patients. E/M levels optimized under 2021 AMA guidelines. PMHNP add-on codes applied on every qualifying combined session. AWV codes applied correctly with combination billing for same-day problems. Telehealth POS corrected per payer.

Result for NP practices: Incident-to billing adds 15% to qualifying Medicare visit revenue — immediate and recurring. CCM activation adds $2,000–$6,000 per month in previously uncaptured revenue. Annual revenue improvements of $100,000–$170,000 for solo NP practices.

8. Endocrinology Billing Services

Why Endocrinology Billing Is Different

Endocrinology billing combines high-complexity chronic disease management coding — diabetes ICD-10 complication coding with secondary codes, Z79.4 for insulin use — with device-specific billing for continuous glucose monitoring and insulin pumps, and documentation-intensive procedures like DEXA scans and thyroid procedures.

The ICD-10 coding framework for diabetes specifically requires complication-specific codes that most endocrinology billing teams don’t apply consistently — and each complication code affects both the E/M level supported and the medical necessity of monitoring services billed.

What Most Endocrinology Practices Get Wrong

  • Diabetes ICD-10 undercoding: E11.9 (Type 2 diabetes without complications) billed when the documentation clearly supports complication-specific codes (E11.40, E11.51, E11.65) — less specific codes provide weaker medical necessity support for monitoring services
  • Z79.4 secondary code missing: Patients on insulin not coded with Z79.4 — missing a code that affects E/M complexity level and medication management documentation
  • CGM billing errors: CPT 95250/95251 for CGM analysis billed without required documentation; A9276–A9278 supply codes and K0553 not captured
  • Insulin pump billing incomplete: E0784 billed without A4224–A4232 supply codes — supply revenue uncaptured
  • CCM not activated: Endocrinology patients with diabetes and comorbidities — high CCM eligibility rate, low CCM billing rate
  • DEXA authorization gaps: Medicare bone density scan frequency rules not tracked — claims denied for non-covered frequency

How Malakos Helps

Diabetes ICD-10 complication coding is applied at maximum specificity supported by documentation — E11 codes with full complication descriptors, Z79.4 applied for insulin users, sequencing rules followed per 2026 tabular guidance. CGM billing verified for documentation compliance before 95250/95251 is submitted. CGM supply codes and insulin pump supplies captured alongside device codes. CCM activated for qualifying endocrinology patients. DEXA frequency tracked per patient per Medicare coverage rules.

Result for endocrinology practices: Diabetes coding specificity improves E/M level support and medical necessity standing for monitoring services. CGM and insulin pump supply revenue captured. CCM activates a new monthly revenue stream. Annual revenue improvements of $70,000–$140,000 for solo and two-physician endocrinology practices.

How to Get Started — The Free Billing Audit

Every Malakos Healthcare Solutions engagement begins with a free billing audit — a review of your current claims data, denial patterns, AR aging, coding distribution, and revenue cycle performance.

The audit identifies your practice’s specific revenue gaps in dollar terms — how much imaging guidance is uncaptured in your pain management practice, what your CCM revenue opportunity is in your family medicine panel, how much your chiropractic group is losing to CMT undercoding — before any commitment is made.

The audit is free. The findings are yours. No commitment required.

Most practices that complete a Malakos billing audit find the revenue gap is larger than they expected. All of them find it is actionable.

Your specialty. Your billing complexity. Our expertise.
