Documentation tips

What should appear in the chart to support M76.11.

Source · Editorial brief grounded in 4 cited references ↓

Provider must explicitly document right-sided psoas tendinitis — 'hip flexor tendinitis' or 'groin pain' alone is insufficient to support M76.11.
Record the mechanism or clinical context: insidious onset vs. activity-related, duration, and prior conservative care (physical therapy, NSAIDs, activity modification).
If imaging was performed, note relevant findings: ultrasound evidence of tendon thickening, peritendinous edema, or MRI signal change along the psoas tendon.
If bilateral involvement is confirmed, document both right and left sides explicitly so both M76.11 and M76.12 can be billed — do not leave laterality to inference.
For injection procedures, document the target structure by name (psoas tendon sheath, iliopsoas bursa) to support the correct CPT code and to distinguish from adjacent structures.

Common coding pitfalls

The recurring mistakes coders make with M76.11 and adjacent codes.

Source · Editorial brief grounded in CDC ICD-10-CM tabular guidance, AAOS coding references, and cited references ↓

Using M76.10 (unspecified hip) when laterality is clearly documented in the note — always capture the more specific code.
Coding M76.11 for a traumatic psoas strain; acute injury to the psoas tendon or muscle belongs in the S76.1x- series with the appropriate 7th character (A, D, or S).
Conflating psoas tendinitis with iliopsoas bursitis (M70.71, right hip) — these are distinct structures and distinct codes; select based on the provider's documented diagnosis.
Reporting a single bilateral code that does not exist — ICD-10-CM requires M76.11 plus M76.12 when both sides are affected.
Dropping to M25.551 (pain in right hip) when the provider has specified psoas tendinitis — always code to the highest level of specificity supported by documentation.

Clinical context

Source · Editorial summary grounded in 4 cited references ↓

M76.11 is the billable code for psoas tendinitis of the right hip. Use it when the provider has documented right-sided psoas tendon inflammation — not a psoas strain, not iliopsoas bursitis, and not a nonspecific hip pain complaint. The psoas tendon is the primary hip flexor; tendinitis here typically presents as anterior groin or hip pain that worsens with active hip flexion, prolonged sitting, or stair climbing.

This code sits within the M76 enthesopathy family (lower limb, excluding foot). Laterality is built into the 6th character: M76.11 = right, M76.12 = left, M76.10 = unspecified. If bilateral involvement is documented, report M76.11 and M76.12 together — ICD-10-CM has no single bilateral code for psoas tendinitis. The approximate synonym 'bilateral psoas tendinitis' in some databases does not map to a dedicated bilateral code; each side must be coded separately.

MS-DRG v43.0 groups M76.11 into DRGs 557 (tendonitis, myositis and bursitis with MCC) and 558 (without MCC), which affects inpatient facility reimbursement. Outpatient orthopedic visits most commonly pair this diagnosis with E/M codes, imaging, or injection procedures. Confirm the provider's language distinguishes tendinitis from a traumatic psoas strain (S76.1x-) or from iliopsoas bursitis (M70.7x) — these map to different code families and different clinical pathways.

Frequently asked questions

Source · Generated from the editorial pipeline, verified against 4 cited references ↓

01Is there a single ICD-10-CM code for bilateral psoas tendinitis?

No. Code both M76.11 (right) and M76.12 (left) when the provider documents bilateral involvement. Some reference databases list 'bilateral psoas tendinitis' as an approximate synonym for M76.11, but that is a cross-reference artifact — no dedicated bilateral code exists in the tabular list.

02When should I use M76.11 vs. M70.71 for right hip pain involving the hip flexor region?

M76.11 is psoas tendinitis (tendon inflammation); M70.71 is other bursitis of the right hip, which includes ischial bursitis. If the provider documents iliopsoas bursitis specifically, M70.71 is the better fit. When the diagnosis is psoas or iliopsoas tendinitis, use M76.11. Choose based on the provider's documented structure and diagnosis, not just anatomic proximity.

03Can M76.11 be used for a traumatic psoas injury sustained during a sporting event?

Not if the condition is an acute strain. An acute traumatic injury to the psoas muscle or tendon maps to S76.1x- (strain of iliopsoas muscle/tendon at hip level) with the appropriate 7th character. M76.11 is appropriate for non-traumatic, inflammatory tendinitis. If there is a traumatic component, the external cause code should be appended per ICD-10-CM Chapter 13 instructions.

04What MS-DRGs does M76.11 map to for inpatient billing?

M76.11 groups to MS-DRG 557 (tendonitis, myositis and bursitis with MCC) and MS-DRG 558 (without MCC) under MS-DRG v43.0. Whether the patient qualifies for 557 depends on the presence of a documented major complication or comorbidity.

05Does M76.11 require a 7th character?

No. M76.11 is a complete, billable code with no 7th-character extension required. The 7th-character A/D/S convention applies to injury codes in the S-code range, not to M-code enthesopathy diagnoses.

06What CPT codes are commonly paired with M76.11 in an outpatient orthopedic setting?

Common pairings include office E/M codes (99213, 99214), hip or pelvis MRI or ultrasound imaging codes, therapeutic injection into the tendon sheath or adjacent bursa (20610, 20552), and physical therapy procedure codes (97110, 97530) when physical therapy is ordered alongside the orthopedic visit.

07What is the earliest date of service for which M76.11 is valid?

M76.11 was introduced as a new code effective October 1, 2015 (FY2016 ICD-10-CM). Claims with dates of service before that date require ICD-9-CM codes. The code has remained unchanged through the FY2026 code set (effective October 1, 2025).

Mira AI Scribe

Mira captures laterality (right), the involved structure (psoas tendon), onset pattern, aggravating activities, prior treatment attempts, and any imaging findings (ultrasound or MRI tendon changes) from the encounter note. This prevents down-coding to M76.10 (unspecified) or M25.551 (hip pain NOS), both of which carry lower diagnostic specificity and can trigger payer requests for additional documentation.
