Sleep Study Order Note (PSG/HSAT Medical Necessity)

Date/Time: [Order date and time]
Encounter Type: [in-person / telemedicine]
Ordering Clinician: [Name, credentials]
Referring Clinician: [Name, credentials] (Omit if not applicable)
Test Requested: [HSAT / In-Lab PSG / In-Lab PSG—split-night anticipated]
Suspected Diagnosis: [e.g., suspected OSA, other sleep-related breathing disorder]
ICD-10 Code(s): [Code(s)] (Only include if known at order time; otherwise omit)

Reason for Sleep Study

[Chief complaint with brief direct quote if useful, noting reporter (patient vs. bed partner). Clinical concern for sleep-disordered breathing and functional or safety impact.]

Sleep-Related History

(Document in problem-oriented format. If a core symptom domain was not assessed, write "Not assessed" rather than omitting.)

• Nighttime symptoms:
  • [Snoring frequency and intensity]
  • [Witnessed apneas (reporter and frequency)]
  • [Gasping/choking awakenings]
  • [Sleep fragmentation / awakenings per night]
  • [Nocturia frequency]
  • [Morning headaches, dry mouth, or sore throat]
• Daytime symptoms:
  • [Excessive daytime sleepiness / propensity to doze with context]
  • [Fatigue or low energy]
  • [Cognitive or mood symptoms]
  • [Safety concerns: drowsy driving, near-miss incidents] (Use brief direct quotes for safety-critical statements)
• Course and context:
  • [Duration and progression]
  • [Triggers or modifiers (weight change, medications, alcohol/sedatives)]
  • [Prior interventions and responses]

Risk Factors

(Omit this section entirely if no risk factor data available.)

• [BMI with source/date] (Include if available)
• [Neck circumference] (Include if measured)
• [Relevant risk context: age, craniofacial features, family history of OSA]
• [Epworth Sleepiness Scale: score and date] (Only include if collected; present as supporting pretest probability, not diagnostic)
• [STOP-BANG: score and date] (Only include if collected; present as supporting pretest probability, not diagnostic)

Comorbidities Affecting Test Selection

(Explicitly state presence or absence for each; do not infer severity beyond documentation. This section supports HSAT appropriateness vs. need for PSG.)

• Significant cardiopulmonary disease (CHF, moderate–severe pulmonary disease): [present / absent / not assessed] [Details if present]
• Neuromuscular disease with respiratory weakness: [present / absent / not assessed] [Details if present]
• Prior stroke: [present / absent / not assessed] [Date or residual deficits if relevant]
• Suspected hypoventilation (e.g., obesity hypoventilation): [present / absent / not assessed] [Supporting data if present]
• Chronic opioid therapy: [present / absent / not assessed] [Agent/dose if relevant]
• Severe insomnia: [present / absent / not assessed] [Impact if present]
• Suspicion for non-OSA sleep disorder requiring PSG (central sleep apnea, parasomnia with injury risk, PLMD, narcolepsy/hypersomnia): [present / absent / not assessed] [Specify if present]

Pertinent Exam Findings

(Include only if relevant exam or objective data obtained. Omit this section entirely if none.)

• [Blood pressure, heart rate] (Include if measured)
• [Resting SpO2] (Include if available)
• [Upper airway findings: nasal patency, tonsillar size, Mallampati] (Include if examined)
• [Body habitus observations] (Include if examined)

(If telemedicine) Exam limited by telemedicine. [Recent objective data if available]

Medical Necessity & Test Rationale

[HSAT / PSG] is ordered to evaluate [clinical question: diagnostic confirmation of suspected OSA / evaluation for specified sleep pathology].

(If HSAT ordered)

The patient is an adult with symptoms suggesting at least moderate risk for OSA. No PSG-driving comorbidities are identified (see Comorbidities Affecting Test Selection above). HSAT is ordered as part of a comprehensive sleep evaluation with planned follow-up. If HSAT is negative, inconclusive, or technically inadequate and clinical suspicion remains, in-lab PSG will be pursued.

(If PSG ordered)

PSG is indicated due to [specific indication(s): complicating cardiopulmonary/neuromuscular disease, suspected hypoventilation, concern for non-OSA sleep disorder, prior HSAT negative/inconclusive/technically inadequate with persistent suspicion, or need for capabilities beyond HSAT]. (If split-night requested) Split-night is requested due to high suspicion for moderate–severe OSA with anticipated need for same-night PAP titration.

Medical Necessity Summary: [Key symptoms supporting concern for OSA or other sleep disorder]. [Functional impact or interaction with comorbidities]. [Why the selected modality is appropriate for this clinical scenario].

Plan & Follow-Up

• Results review: [Follow-up timeframe and modality]
• Anticipated next steps: [PAP initiation / oral appliance referral / positional therapy / weight management / specialty referral as applicable based on results]
• Safety counseling: [Counseling regarding driving and high-risk activities] (Include if significant daytime sleepiness present)
• Escalation plan: [Urgency considerations and specialty coordination] (Include if comorbidities elevate urgency)
